With Greer expertise as part of today’s Parker advantage for the oil and gas industry, we are a major supplier of 10-, 11- and 15-gallon bladder accumulators with pressure capabilities up to 6,600 PSI. Parker offers a complete line of accessories that complement and enhance the accumulator operation. Hydro-pneumatic accumulators are the most widely used type of accumulator in industrial and mobile hydraulic systems. They use compressed gas to apply force to hydraulic fluid. Identical in their operating principle, Parker’s piston, bladder and diaphragm accumulators use different mechanisms to separate the gas from the fluid. It is this difference – and the resulting performance characteristics – which determines the appropriate style accumulator for different applications. Adding an accumulator to a hydraulic system can: • improve system efficiency • absorb shock • supplement pump delivery • provide emergency power • compensate for leakage • maintain pressure • dispense fluid • compensate for slow component response 3 Industry-Leading Experience and Capabilities With more years of experience than any other name, Parker Hannifin’s Global Accumulator Division is the industry leader in accumulator solutions for energy optimization.

Certifications for Global Requirements Certifications for accumulators vary – often quite significantly – depending upon the application they will be used for and the country they will be used in. Sorting through the myriad of requirements that may be encountered is a daunting and difficult task. A truly global certification standard, meanwhile, remains all but impossible to achieve due to the parameters that must be met for individual country regulations. Parker’s Global Accumulator Division engineers have extensively researched and fully understand these pressure vessel codes. From the United States to Europe, Asia and Australia, our experts are ready and able to help you avoid the many costly and timeconsuming pitfalls you didn’t see coming. Furthermore, GAD can provide the global accumulator certifications you need. Accumulators and gas bottles are pressure vessels that are subject to safety laws, regulations, and ordinances that are valid in the state or country of installation. Other particular regulations must be observed in certain industries such as mining, shipbuilding and aircraft. This Brief will discuss the two fundamental design codes and several of the most common certifications. Since many more certifications exist, we recommend contacting Parker’s Global Accumulator Division engineers to insure proper conformance to those standards. Two Base Design Codes While many countries have their own regulations and quality standards for hydraulic accumulators, most refer back to one of two base design codes. The oldest and most referenced design code for pressure vessels is ASME. Originally written to create a standard for the manufacture of boilers on steam locomotives, the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section VIII, Division 1 has evolved into requirements for unfired pressure vessels and accumulators in the United States. This section requires the following: 1. Certification on vessels with internal diameters of 6″ or greater. 2. Certified vessels carry the “U” symbol on them as evidence that they were designed and manufactured in accordance with the Code. The “U” symbol is an internationally recognized symbol of design and manufacturing quality. 3. Accumulators must be manufactured from materials that meet ASME specifications for traceability. 4. A design factor of 4:1 in the ratio of minimum burst pressure to rated pressure. All design factors are with respect to the specified minimum tensile strength of the material. 5. ASME requires that each vessel be marked with the design pressure at the Minimum Design Metal Temperature (MDMT) for the vessel. 6. Surveillance of an approved quality system, like ISO 9001. 7. All hydrostatic testing to be witnessed by a recognized authorized inspection agency. The 4:1 design factor requirement is mandatory for all accumulators with ASME Certification with the exception of those that comply with a specific rule within the Code called “Appendix 22.” Appendix 22 permits that accumulators manufactured with “forged” shells and with openings of a specified maximum size may be certified with a design factor of 3:1 in the ratio of burst pressure to rated pressure. This includes bladder style accumulators. The second base design code is the European Pressure Equipment Directive. In May 2002, the Directive 97/23/EC (Pressure Equipment Directive) came into regulation in the European Union. This Directive applies to the design, manufacture, testing and conformity assessment of pressure equipment and assemblies of pressure equipment that operate over 0.5 bar. The directive requires the following: 1. The operating fluids must be in Group 2 (non-hazardous). 2. Certified vessels with a volume greater than 1 liter gas capacity must be CE marked. 6 3. Certified vessels must be manufactured from materials that meet PED specifications for traceability. 4. Certified product must pass a low temperature Charpy test (temperature to be determined by application or customer). 5. Surveillance of an approved quality system, such as ISO 9001. 6. All hydrostatic testing to be witnessed by an approved notified body. Parker holds module H1 certification – allowing us to self certify accumulators saving our customers time and money. 7. Once installed, equipment and accumulator inspection as well as operational safety are controlled by national laws. Accumulators with a volume less than 1 liter, of gas capacity, fall within the guidelines of Sound Engineering Practice (SEP). Accumulators built to SEP must be built to a known standard and have an approved notified body approve the design and the technical file. These accumulators DO NOT carry a CE marking. Country Certifications Below is a brief list of the most popular country standards that Parker GAD can provide: 1. Canada: Canadian Registration Numbers (CRN) can be obtained by constructing an accumulator from ASME-certified material using ASME standards of design then applying for the registration number. Each province has its own registration number, thus the end destination of the accumulator must be known. Some provinces are allowing alternative design codes like the PED for specific markets such as farming and mining. Contact Parker GAD for detailed specifics. 2. Australia: AS1210 is a standard based on ASME design requirements. Additional hydrostatic testing is required. The accumulator must be tested at 1.5 times the design pressure for 30 minutes plus an additional 1 minute per mm of thickness of the shell/vessel. 3. China: Accumulators shipped to China often require Special Equipment Licensing Office (SELO) approval. China currently accepts both PED and ASME design standards. To manufacture accumulators for the Chinese marketplace, a manufacturing license is required. Paperwork both before and after the purchase of the accumulator is required for submittal to China for tracking purposes. 4. Russia: Accumulators shipped to Russia often require GOST approval. GOST currently accepts both PED and ASME design standards. A technical file called a “passport” must be submitted with each accumulator shipment. 5. Brazil: The Regulatory Rule NR-13 establishes the minimum conditions for the installation, operation, maintenance and inspection of pressure vessels and boilers in Brazil. Both ASME and the PED are acceptable design codes, but ASME designs are more prevalent. When NR-13 is required, Parker’s engineers can submit a technical file to Brazilian Registered Engineers (BRE) for approval. After approval, an inspection at the place of installation will be performed by the BRE. This could also include hydrostatic testing. Industry/Market Standards 1. American Bureau of Shipping (ABS): Is required for accumulators installed on shipping vessels and oil rigs. To be added to a Product Design Assessment Certificate, accumulators must meet ASME design requirements plus any additional ABS requirements. Parker has an ABS Certificate of Manufacturing Assessment and many accumulators are listed on the Bureau’s List of Type Approved Products. All ABSapproved accumulators must be witness tested at Parker by an ABS inspector. 2. Det Norske Veritas (DNV): Off-shore Standard DNVOS- E101 is often required for accumulators on off-shore oil and gas applications, particularly in the North Sea. Many of Parker’s accumulators have DNV Type Approval. Additional Information GAD also offers dual-certified ASME/ CE accumulators. No matter where you need to be, Parker’s Global Accumulator Division will be there to support you with the necessary products, services and global certifications. 7 Selecting and Applying Accumulators In industrial and mobile applications, three types of hydro-pneumatic accumulators – piston, bladder and diaphragm – are used. Each has particular advantages and limitations which should be considered when selecting an accumulator for a specific application.

They provide excellent gas/fluid separation. Piston accumulators offer greater efficiency and flexibility in most applications, due to their wider range of sizes. Parker’s piston accumulators feature a five-blade V-O-ring which maintains full contact between the piston and the bore, without rolling. Sealing remains effective even under rapid cycling at high operating pressures. Note: Failure or improper selection or improper use of accumulators or related items can cause death, personal injury and property damage. Parker Hannifin shall not be liable for any incidental, consequential or special damages that result from use of the information contained in this publication. 8 Bladder accumulators Parker’s bladder accumulators feature a non-pleated, flexible rubber bladder housed within a steel shell. A steel gas valve is molded on the top of the bladder. A poppet valve, normally held open by spring force, prevents the bladder from extruding through the port when the bladder is fully expanded in the shell. Parker’s bladder accumulators are available as either top or bottom repairable units, for optimum flexibility. Diaphragm accumulators Parker’s diaphragm accumulators feature a one-piece molded diaphragm which is mechanically sealed to the high strength metal shell. The flexible diaphragm provides excellent gas and fluid separation. The non-repairable electron-beam welded construction reduces size, weight, and ultimately cost. The bladder/diaphragm is charged with a dry inert gas, such as high purity nitrogen, to a set precharge pressure determined by the system requirements. As system pressure fluctuates, the bladder/diaphragm expands and contracts to discharge fluid from, or allow fluid into, the accumulator shell. Piston accumulators Parker’s piston accumulators consist of a cylindrical body, sealed by a gas cap and charging valve at the gas end, and by a hydraulic cap at the opposite end. A lightweight piston separates the gas side of the accumulator from the hydraulic side. As with the bladder/diaphragm accumulator, the gas side is charged with high purity nitrogen to a predetermined pressure. Changes in system pressure cause the piston to glide up and down along the shell, allowing fluid to enter or forcing it to be discharged from the accumulator body. Design Features and Construction Fig. 1 Typical bladder, diaphragm and piston accumulator cross section BLADDER DIAPHRAGM PISTON 9 Operation Stage A The accumulator is empty, and neither gas nor hydraulic sides are pressurized. Stage B The accumulator is precharged. Stage C The hydraulic system is pressurized. As system pressure exceeds gas precharge hydraulic pressure fluid flows into the accumulator. Stage D System pressure peaks. The accumulator is filled with fluid to its design capacity. Any further increase in hydraulic pressure is prevented by a relief valve in the hydraulic system. Stage E System pressure falls. Precharge pressure forces fluid from the accumulator into the system. Stage F Minimum system pressure is reached. The accumulator has discharged its design maximum volume of fluid back into the system. Fig. 2 Operating conditions of bladder, piston, and diaphragm style accumulators DIAPHRAGM PISTON BLADDER * * * Do not return to initial precharge level * 10 When selecting an accumulator for a particular application, both hydraulic system and accumulator performance criteria should be considered. To ensure long and satisfactory service life, the following factors should be taken into account: • failure mode • output volume • flow rate • fluid type • response time • shock suppression • high-frequency cycling • mounting position • external forces • sizing information • certification • safety • temperature effect • dwell time Failure modes In certain applications, a sudden failure may be preferable to a gradual failure. A high-speed machine, for example, where product quality is a function of hydraulic system pressure. Because sudden failure is detected immediately, scrap is minimized, whereas gradual failure might mean that production of a large quantity of sub-standard product could occur before the failure became apparent. A bladder/ diaphragm accumulator would be most suitable for this application. Conversely, where continuous operation is paramount and sudden failure could be detrimental, for example, in a braking or steering circuit on mobile equipment, a progressive failure mode is desirable. In this application, a piston accumulator would be appropriate. Output volume The maximum available capacity of each type of accumulator determines the limits of their suitability where large output volumes are required. There are, however, several methods of achieving higher output volumes than standard accumulator capacities suggest (see Large/ Multiple Accumulators, page 15). Table 1 compares typical fluid outputs for Parker’s 10-gallon piston and bladder accumulators operating isothermally as auxiliary power sources over a range of minimum system pressures. The higher precharge pressures recommended for piston accumulators result in higher outputs than from comparable bladder accumulators. Also, bladder accumulators are not generally suitable for compression ratios greater than 4:1, as these could result in excessive bladder deformation, higher gas temperature, excessive side wall wear, and eventual failure. Piston accumulators have an inherently higher output relative to their overall dimensions, which may be critical in locations where space is limited. Piston accumulators are available in a choice of diameters and lengths for a given capacity, whereas bladder and diaphragm accumulators are frequently offered in only one size per capacity, and fewer sizes are available. Piston accumulators can also be built to custom lengths for applications in which available space is critical. Flow rate Table 2 shows typical maximum flow rates for Parker’s accumulator styles in a range of sizes. The larger standard bladder accumulator designs are limited to 220 GPM, although this may be increased to 600 GPM using a larger high-flow port. Flow rates greater than 600 GPM may be achieved by mounting several accumulators on a common manifold. (see Large/ Multiple Accumulators, page 15).

Flow is limited by piston velocity, which should not exceed 10 ft/sec. to avoid piston seal damage. In high-speed applications, high seal contact temperatures and rapid decompression of nitrogen that has permeated the seal itself, can cause blisters, cracks and pits on the seal surface. Contamination / Fluid type Bladder/diaphragm accumulators are more resistant to damage caused by contamination of the hydraulic fluid than piston types. While some risk exists from contaminants trapped between the bladder and the shell, a higher risk of failure exists from the same contaminants acting on the piston seal. Bladder accumulators are usually preferred to piston type accumulators for water service applications. Water systems tend to carry more solid contaminants and lubrication is poor. Both the piston and bladder type units require some type of preparation to resist corrosion on the wetted surfaces. Piston accumulators are preferred for systems using exotic fluids or where extremes of temperature are experienced as compared to bladders. Piston seals are more easily molded in the required special compounds, and may be less expensive. Response time In theory, bladder/diaphragm accumulators should respond more quickly to system pressure variations than piston accumulator types, since there is no static friction to overcome with a piston seal, and there is no piston mass to be accelerated or decelerated. This is particularly true in small capacity, lower pressure applications. In practice, however, the difference in response is not great, and is probably insignificant in most applications. This applies equally in servo applications, as only a small percentage of servos require response times of 25 ms or less. This is the point where the difference in response between piston and bladder accumulators becomes significant. Generally, a bladder accumulator should be used for applications requiring less than 25 ms response time, and either accumulator type for a response of 25 ms or greater. Shock suppression Shock control does not necessarily demand a bladder/diaphragm accumulator. Example 1 A test circuit (Fig. 3) includes a control valve situated 118 feet from a pump supplying fluid at 29.6 GPM. The circuit uses 1.25-inch tubing, and the relief valve is set to open at 2750 PSI. Shutting the control valve (Fig. 4) produces a pressure spike of 385 PSI over relief valve setting (blue trace). Fig. 3 Test circuit to generate and measure shock waves in a hydraulic system Fig. 4 Shock wave test results – Example 1 Fig. 5 Shock wave test results – Example 2 12 Installing a Parker one-gallon piston accumulator at the valve reduces the transient to 100 PSI over relief valve setting (green trace). Substituting a one-gallon bladder accumulator further reduces the transient to 80 PSI over relief valve setting (red trace), an improvement of only 20 PSI and of little practical significance. Example 2 A second, similar test using 0.625-inch tubing and a relief valve setting of 2650 PSI (Fig. 5) results in a pressure spike of 2011 PSI over relief valve setting without an accumulator (blue trace). A Parker piston accumulator reduces the transient to 107 PSI over relief valve setting (green trace), while a bladder accumulator achieves a transient of 87 PSI over relief valve setting (red trace). The difference between accumulator types in shock suppression is again negligible. High-frequency cycling High-frequency system pressure cycling can cause a piston accumulator to ‘dither’, with the piston cycling rapidly back and forth in a distance less than its seal width. Over an extended period, this condition may cause heat buildup under the seal due to lack of lubrication, resulting in seal and bore wear. For high frequency dampening applications, therefore, a bladder/diaphragm accumulator was generally used. However, Parker has recently developed special piston seals that perform as effective as bladder/diaphragm accumulators. Mounting position The optimum mounting position for any accumulator is vertical, with the hydraulic port downwards. Piston accumulators can be mounted horizontally if the fluid is kept clean but, if solid contaminants are present or expected in significant amounts, horizontal mounting can result in uneven or accelerated seal wear. A bladder accumulator may also be mounted horizontally, but uneven wear on the side of the bladder as it rubs against the shell while floating on the fluid can reduce its service life and even cause permanent distortion. The extent of the damage will depend upon fluid cleanliness, cycle rate and compression ratio (i.e., maximum system pressure divided by minimum system pressure). In extreme cases, fluid can be trapped away from the hydraulic port (Fig. 6), reducing output, as the bladder extends, forcing the poppet valve to close prematurely. Horizontal mount in high-flow applications is not recommended as the bladder can be pinched by the poppet. External forces Any application subjecting an accumulator to acceleration, deceleration or centrifugal force may have a detrimental effect on its operation, and could cause damage to a bladder accumulator. Forces along the axis of the tube or shell normally have little effect on a bladder accumulator but may cause a variation in gas pressure in a piston accumulator due to the mass of the piston. Forces perpendicular to an accumulator’s axis should not affect a piston accumulator, but fluid in a bladder accumulator may be thrown to one side of the shell (Fig. 7), displacing the bladder and flattening and lengthening it. In this condition, fluid discharge could cause the poppet valve to pinch and cut the bladder. Higher precharge pressures increase the resistance of the bladder to the effects of perpendicular forces. Sizing information Accurate sizing of an accumulator is critical if it is to deliver a long and reliable service life. Information Fig. 6 A horizontally mounted bladder accumulator can trap fluid away from the hydraulic valve Fig. 7 Perpendicular force causes the mass of the fluid to displace the bladder 13 and worked examples are shown in Parker’s accumulator catalogues, or accumulator size can be calculated automatically by entering application details into Parker’s accumulator inPHorm software selection program.

Safety Hydro-pneumatic accumulators should always be used in conjunction with a safety block, to enable the accumulator to be isolated from the circuit in an emergency or for maintenance purposes. Remote gas storage offers installation flexibility where the available space or position cannot accommodate an accumulator of the required size. A smaller accumulator may be used in conjunction with a Parker auxiliary gas bottle, which can be located elsewhere (Fig. 8). The gas bottle is sized by the formula: For Piston: gas bottle size = accumulator size – (required output from accumulator x 1.1) For Bladder Type Accumulators: gas bottle size = accumulator size – (required output from accumulator x 1.25) For example, an application that calls for a 30-gallon accumulator may only actually require eight gallons of fluid output. This application could therefore be satisfied with a 10-gallon accumulator and a 20-gallon gas bottle. Gas bottle installations may use either bladder or piston accumulators, subject to the following considerations: • Any accumulator used with remote gas storage should generally have the same size port at the gas end as at the hydraulic end, to allow an unimpeded flow of gas to and from the gas bottle. The gas bottle will have an equivalent port in one end and a gas charging valve at the other. • A piston accumulator should be carefully sized to prevent the piston bottoming at the end of the cycle. Bladder accumulators should be sized to prevent filling to more than 75% full. • Bladder accumulators require a special device called a transfer barrier tube at the gas end, to prevent extrusion of the bladder into the gas bottle piping. The flow rate between the bladder transfer barrier tube and its gas bottle will be restricted by the neck of the transfer barrier tube. • Because of the above limitations, piston accumulators are generally preferred to bladder types for use in gas bottle installations. • Diaphragm accumulators are normally not used in conjunction with gas bottles. Fig. 8 An accumulator can be used with a remote gas bottle where space is critical The bladder/transfer barrier should never be filled more than 75% full Gas Bottle Installations 14 The requirement for an accumulator with an output of more than 50 gallons cannot usually be met by a single accumulator, because larger piston designs are relatively expensive, and bladder designs are not generally available in these sizes. The requirement, however, can be met using one of the multiplecomponent installations shown in Figs. 9 and 10. The installation in Fig. 10 consists of several gas bottles serving a single piston accumulator through a gas manifold. The accumulator portion may be sized outside of the limitations of the sizing formula on page 14, but should not allow the piston to strike the caps repeatedly while cycling. The larger gas volume available with this configuration allows a relatively greater piston movement – and hence fluid output – than with a conventionally sized single accumulator. A further advantage is that, because of the large precharge ‘reservoir’, gas pressure is relatively constant over the full discharge cycle of the accumulator. The major disadvantage of this arrangement is that a single seal failure could drain the whole gas system. Note: The addition of individual isolation valves on the gas bottles remedies this issue. The installation in Fig. 9 uses several accumulators, of piston or bladder design, mounted on a hydraulic manifold. Two advantages of multiple accumulators over multiple gas bottles are that higher unit fluid flow rates are permissible, and a single leak will not drain precharge pressure from the entire system. A potential disadvantage is that, where piston accumulators are used, the piston with the least friction will move first and could occasionally bottom on the hydraulic end cap. However, in a slow or infrequently used system, this would be of little significance. Large/Multiple Accumulators Fig. 9 Multiple accumulators manifolded together offer high system flow rates Fig. 10 Several gas bottles can supply precharge pressure to a single accumulator 15 Precharging Fig. 13 Fluid entering an un-precharged bladder accumulator has forced the bladder into the gas stem Precharging process Correct precharging involves accurately filling the gas side of an accumulator with a high purity dry, inert gas, before admitting fluid to the hydraulic side. It is important to precharge an accumulator to the correct specified pressure. Precharge pressure determines the volume of fluid retained in the accumulator at minimum system pressure. In an energy storage application, a bladder/diaphragm accumulator is typically precharged to 90% of minimum system pressure, and a piston accumulator to 95% of minimum system pressure at the system operating temperature. The ability to correctly carry out and maintain precharging is an important factor when choosing the type of accumulator for an application. Bladder accumulators are far more susceptible to damage during precharging than piston types. Before precharging and entering in service, the inside of the shell should be thoroughly lubricated with system fluid. This fluid acts as a cushion, and lubricates and protects the bladder as it expands. When precharging, the first 50 PSI of nitrogen should be introduced slowly. Failure to follow this precaution could result in immediate bladder failure: highpressure nitrogen, expanding rapidly and thus cold, could form a channel in the folded bladder, concentrating at the bottom. Once the poppet valve has closed, the precharge can be increased to the desired pressure. The chilled, brittle rubber, expanding rapidly would then inevitably rupture (Fig. 11). The bladder could also be forced under the poppet, resulting in a cut (Fig. 12). Close attention should be paid to operating temperature during precharging, as a rise in temperature will cause a corresponding increase in pressure which could then exceed the precharge limit. Little damage can occur when precharging or checking the precharge on a piston accumulator, but care should be taken to make sure the accumulator is void of all fluid to prevent getting an incorrect reading on the precharge. The protective cover on the hydraulic port must be removed prior to precharging. This will prevent the cover from flying off if the piston is not resting on the hydraulic cap. Excessively high precharge Excessive precharge pressure or a reduction in the minimum system pressure without a corresponding reduction in precharge pressure may cause operating problems or damage to accumulators. With excessive precharge pressure, a piston accumulator will cycle between stages (e) and (b) of Fig. 2, and the piston will travel too close to the hydraulic end cap. The piston could bottom at minimum system pressure, reducing output and eventually damaging the piston and piston seal. The piston can often be heard bottoming, warning of impending problems. An excessive precharge in a bladder accumulator can drive the bladder into the poppet assembly when cycling between stages (e) and (b). This could cause fatigue failure of the poppet spring assembly, or even a pinched and cut bladder, should it become trapped beneath the poppet as it is forced closed (Fig. 12). Excessive precharge pressure is the most common cause of bladder failure. Excessively low precharge Excessively low precharge pressure or an increase in system pressure without a corresponding increase in precharge pressure can also cause operating problems and subsequent 16 Fig. 11 (Left) Starburst rupture caused by loss of bladder elasticity Fig. 12 (Right) C-shaped cut shows that bladder has been trapped under poppet accumulator damage. With no precharge in a piston accumulator, the piston will be driven into the gas end cap and will often remain there. Usually, a single contact will not cause any damage, but repeated impacts will eventually damage the piston and seal. Conversely, for a bladder accumulator, too low or no precharge can have rapid and severe consequences. The bladder will be crushed into the top of the shell and can extrude into the gas stem and be punctured (Fig. 13). This condition is known as “pick out.” One such cycle is sufficient to destroy a bladder. Overall, piston accumulators are generally more tolerant of careless precharging. Note: A pick out appears as a pin hole at the base of the bladder stem. Monitoring piston accumulator precharge Several methods can be used to monitor the precharge pressure of Parker’s piston accumulators. Note that, in Fig. 14b, the flat piston must be used to enable the sensor to register its position. • With the hydraulic system shut down, cool and accumulator emptied of fluid: A pressure transducer or gauge located in the gas end cap (Fig. 14a) indicates the true precharge pressure. • In applications where an accumulator is coupled to a gas bottle: A Hall Effect proximity sensor can be installed in the accumulator gas end cap (Fig. 14b) to detect when the piston comes within .050 inch of the cap. This system would provide a warning when precharge pressure has dropped and remedial action should be taken. Fig. 14a Pressure transducer measures actual precharge pressure of shut down system Fig. 14b Hall Effect sensor registers proximity of piston to end cap 17 • In applications where it is desirable to know when the piston is approaching the gas cap of the accumulator or to detect a low precharge, as the rod is detected by the reed or proximity switch, the switch could be set up to send out a warning signal (Fig. 14c). When used with a pressure switch, it could detect a low precharge. In some instances two reed or proximity switches could be installed on the housing. In such a case it may be required that the first switch is always made, assuring us that the precharge is not too high, if the second switch is made, it would report that the precharge is too low. The position of the piston can be detected by a fraction of an inch to several inches before it reaches the end cap. • When it is required to know the exact location of the piston inside the accumulator, use a linear displacement transducer (LDT) (Fig. 14d). Positions as well as velocity can be determined by the use of this unit. An LDT works by sending a signal down the probe. This signal is then reflected by a magnet attached to a rod and piston assembly. The LDT records the amount of time between sending and receiving the reflected signal and then calculates the position of the piston. Multiple signals will allow the unit to calculate velocity. Using this unit will allow the user to know the exact volume of fluid in the accumulator as well as the flow rate of the fluid. Fig. 14 c Proximity switches can sense the position of an approaching piston Fig. 14d Linear Displacement Transducers (LDT) can accurately detect both piston location and velocity Magnetic 18 Accumulator failure is generally defined as inability to accept and exhaust a specified amount of fluid when operating over a specific system pressure range. Failure often results from an unwanted loss or gain of precharge pressure. Correct precharge pressure is the most important factor in prolonging accumulator life. If maintenance of precharge pressure and relief valve settings is neglected, or if system pressures are adjusted without making corresponding adjustments to precharge pressures, shortened service life will result. Bladder accumulators Bladder/Diaphragm accumulator failure occurs instantaneously from bladder/diaphragm rupture (Fig. 15). Rupture cannot be predicted because the intact bladder or diaphragm is essentially impervious to gas or fluid seepage; no measurable gas or fluid leakage through the bladder or diaphragm precedes failure. Piston accumulators Piston accumulator failure generally occurs in one of the following gradual modes. Fluid leaks to the gas side This failure, sometimes called dynamic transfer, normally takes place during rapid cycling operations after considerable time in service. The worn piston seal carries a small amount of fluid into the gas side with each stroke. As the gas side slowly fills with fluid, precharge pressure rises and the accumulator stores and exhausts decreasing amounts of fluid. The accumulator will totally fail when precharge pressure equals maximum hydraulic system pressure. At that point, the accumulator will accept or deliver any fluid. Because the rise in precharge pressure can be measured (Fig. 16a), failure can be predicted and repairs effected before total failure occurs. Gas leakage Precharge may be lost as gas slowly bypasses damaged piston seals. Seal deterioration occurs from excessively long service, from fluid contamination, or from a combination of the two. Gas can also vent directly through a defective gas core or end cap O-ring. The reducing precharge pressure then forces progressively less fluid into the system. Because this gradual decrease in precharge pressure can be measured (Fig. 16b), repairs can again be effected before total failure occurs. Failure Prevention Fig. 15 When an accumulator bladder ruptures, precharge pressure immediately falls to zero Fig. 16 As fluid leaks past an accumulator piston, precharge pressure rises (a) while gas leaking past the piston or valve causes precharge pressure to fall (b) A correctly specified Parker accumulator, installed and maintained in accordance with the guidelines contained in this section, will give many years of trouble-free use. The combination of clean system fluid and accurate precharging will prevent most of the common fault conditions described here, and will contribute to the long life and high operating efficiency of the entire hydraulic system. It is recommended to use Parker filters to keep contaminants out of your system. 19 Solutions for Oil & Gas and Power Generation For today’s power generation accumulator needs in oil and gas production, wind power, wave power, nuclear, hydro-electric, turbine and valve actuator applications, Parker has the most complete selection of solutions.

Catalog HY10-1630/US Introduction Piston Accumulators Parker Hannifin Global Accumulator Division 27 United States Piston 5000 4000 3000 2000 Design Features & Benefits 3000 Piston type accumulators are designed with compact, rugged steel shell and caps. The steel shell allows heat to dissipate effectively. The bore is micro-finished for extended seal life. The threaded caps allow for easy repair and seal replacement. The piston seal consists of a unique, five-bladed V-O-ring with back-up washers. This design eliminates seal roll-over and ensures total separation of fluid and gas under the most severe operating conditions. The V-O-ring also holds full pressure throughout long idle periods between cycles, providing dependable, full pressure storage of hydraulic energy. It ensures safe, reliable absorption of pressure peaks. The piston seal design helps to prevent sudden failure of the accumulator. The V-O-ring seals are available in a wide variety of compounds to cover a broad range of fluids and operating temperature ranges (see Options). 1 2 7 1 3 2 4 5 6 The lightweight piston design allows fast response to reduce shock in rapid cycling applications. The dished profile of the piston provides extra gas capacity and greater useable volume of fluid. PTFE glide rings eliminate metal-to-metal contact between the tube and piston, reducing wear and extending service life. All piston accumulators are fitted with a standard designed gas valve for ease of gas precharging. Series 3000, 3″ thru 6″ bores, are fitted with standard cored gas valve cartridges (ISO-4570-8V1). The Series 4000 and Series 5000, 3″ thru 6″ bores, have as standard a gas valve with a 5000 PSI high-pressure valve cartridge. Offered as an option is a high flow gas valve (L07689000K). For 7″ thru 12″ bore sizes, the high flow gas valve is standard. The high-flow gas valve is available by special request – please consult factory.

For pressures over 5000 PSI consult factory. Fluids Parker’s piston accumulators are compatible with a wide variety of fluids. Standard accumulators (with nitrile seals) may be used with petroleum-based industrial oils or water-based flame resistant fluids. Optional seals compatible with most industrial fluids are available with temperature ranges from -45°F to 320°F (-43°C to 160°C). Precharge Units are shipped with a nominal nitrogen precharge as standard. For specific precharge pressures, specify at the time of order. Auxiliary Gas Bottles When space does not permit the installation of the required piston accumulator, a smaller accumulator may be used by connecting it to an auxiliary gas bottle(s) that can be located in a nearby spot where space is available. In some cases, a piston accumulator and gas bottle combination may be more economical, especially large capacity sizes. Piston travel, confined to the accumulator, must be calculated with ample margins to store the required fluid. Standard Ports The following ports are supplied as standard on all fluid ends and on the gas end of accumulators ordered for use with gas bottles: Notes: 1) For flange dimensions, see tables below. 2) On standard 7″ & 9″ bore accumulators, both SAE Straight Thread and Flange ports are available as standard. Omit port code for SAE #32 Straight Thread, specify “PL” port code for 2″ Code 61 Flange when ordering. Flange ports are recommended at operating pressures above 2000 PSI due to pressure limitations of most #32 SAE Straight Thread fittings. Gas Valves Two types of gas valves are available on Series 3000 piston accumulators and gas bottles. Units with 3″ thru 6″ bores, are offered with a cored gas valve cartridge (ISO-4570-8V1) as standard.

Rated at 3770, 4000 and 5000 PSI with a design factor of four to one or greater, these accumulators have been tested and proven at -40ºF/C or below, and meet or exceed CSA/CE/ASME standards. ACP Series Piston Accumulators With Working Pressures of 3,770, 4000 and 5000 PSI ACP 3000 2000 Catalog HY10-1630/US Piston Accumulators Parker Hannifin Global Accumulator Division 38 United States Design Features & Benefits ACP Accumulators 6 1 2 2a 2b 3 5 4 Key advantages of the ACP Series: • Higher working-pressure ratings (3770/4000/5000 PSI) meet more applications with fewer sizes needed. • Use of standard components promotes faster delivery of proven designs and lower product cost. • Piston design prevents sudden accumulator failure and is customized to fit the application. • Four bore sizes available for more capacity and price options. • Patented crimped end cap connections provide superior fatigue life compared with welded designs. • “Schrader” style gas valve (industry standard) fits existing charging equipment; “no gas valve” option also available. • Multiple hydraulic port sizes accommodate a wider range of fittings and mounting options. • All standard product is CRN/CSA to -40°C/F. Fluids compatibility Parker’s seal compounds are compatible with a wide variety of fluids. Standard accumulators (with nitrile seals) may be used with petroleum-based industrial oils or waterbased, flame-resistant fluids. Optional seals compatible with most industrial fluids are available with temperature ranges from -45ºF to 320ºF (-43ºC to 160ºC). 1 High-strength, compact steel shell and cap material. Steel shell allows heat to dissipate effectively and is micro-finished for extended seal life. 2 Lightweight piston design allows for fast response to reduce system shock in rapid cycling applications. 2a Piston seal’s unique, five-bladed V-O-ring with backup washers eliminates seal roll-over and ensures total separation of fluid and gas (40 mm size incorporates a T-seal with energized PTFE piston ring). 2b PTFE glide rings eliminate metal-to-metal contact between tube and piston, reducing wear and extending service life. 3 Patented crimped design provides high-strength coupling of caps to steel tube plus superior fatigue life versus welded type connections. 4 “Schrader” style gas valve is standard on all ACP accumulators for ease of precharging. (Pre-charged accumulators are available featuring specially designed threaded plug and no gas valve option.) 5 Gas valve cap protects valve and serves as secondary seal. Knurled cap design allows easy installation without tools. 6 Port types are available in a wide range of female sizes in both SAE and BSPP styles.

Pressure Ratings Parker 4000 & 5000 PSI piston accumulators are all rated at minimum 4 to 1 design factors. Fluids Parker’s piston accumulators are compatible with a wide variety of fluids. Standard accumulators (with nitrile seals) may be used with petroleum-based industrial oils or waterbased flame resistant fluids. Optional seals compatible with most industrial fluids are available with temperature ranges from -45°F to 320°F (-43°C to 160°C). Precharge Units are shipped with a nominal nitrogen precharge as standard. For specific precharge pressures, specify at the time of order. Standard Ports The following ports are supplied as standard on all fluid ends and on the gas end of accumulators ordered for use with gas bottles: Bore Size Standard Ports Standard Models SAE Port Metric Models BSPP Port (in) 3 SAE #12 3/4 4 SAE #16 1 6 SAE #16 1 7 2″ Code 62 Flange 2″ Metric ISO 6162 Flange 9 2″ Code 62 Flange 2″ Metric ISO6162 Flange Gas Valve Series 4000 accumulators and auxiliary gas bottles are equipped with a high pressure cored gas valve cartridge as standard. Series 5000 accumulators and gas bottles with 3″ through 6″ bores are supplied with a high pressure cored gas valve as standard. Models with 7″ and 9″ bores are supplied with a heavy duty, high-pressure, poppet-type gas valve cartridge (L07689000K) as standard. Note: The standard Parker gas cap will accept either style gas valve. Available Options If your application requires a piston accumulator, gas bottle, or special option that falls outside of Parker’s broad offering, consult your local distributor, Parker representative, or the factory with your specific requirements. Parker has the manufacturing and engineering expertise to design and build piston accumulators to your exacting requirements, from simple modifications of standard units to complete designs. Some example of Parker’s past special designs include: • Special and Stainless Steel Materials • High Pressures • Extreme Temperatures • Piston Position and Velocity Sensors and Switches • Special Seals • Non-Standard Capacities • Water Service • Ports • Fixed Gauge Mounts • Fuse Plug Assemblies Auxiliary Gas Bottles When space does not permit the installation of the required piston accumulator, a smaller accumulator may be used by connecting it to an auxiliary gas bottle(s) that can be located in a nearby spot where space is available. In some cases, a piston accumulator and gas bottle combination may be more economical, especially large capacity sizes. Piston travel, confined to the accumulator, must be calculated with ample margins to store the required fluid.

Temperature ranges may vary depending upon fluid used in hydraulic system. ** The temperature listed indicates the operating temperature range of the seals, not the accumulator. For the Minimum Design Metal Temperature (MDMT) of ASME certified accumulators, refer to page 47. Safety Fuse Options (F) Safety Fuses are used as a safety device on accumulators and gas bottles to prevent over-pressurization of gas due to external heat or hydraulic pressure (set at 140% of maximum system pressure to avoid rupture disk fatigue and premature failure). The rupture disks are calibrated to rupture at a pre-determined pressure. Safety fuses are available on most sizes of piston accumulators. Safety fuses can be installed on all piston accumulators by using a fuse adapter. 4″ bore units and above can be equipped with a fuse port machined in the gas cap by specifying the “Safety Fuse Option” (F) at the time of order in the model code, see “How to Order.” The safety fuse assembly and/or fuse adapter must be ordered separately.

The rupture disks are calibrated to rupture at a predetermined pressure. Safety fuses are available on most sizes of piston and bladder accumulators and gas bottles. Safety fuses can be installed on 1 gallon & larger accumulators by using the “Fuse Adapter” as shown to the right. The safety fuse assembly and/or fuse adapter must be ordered separately.

All attempts have had one thing in common: they never quite solved the problem. Then came Greer’s Pulse-Tone concept, a patented breakthrough in pulsation control. The trouble with the previous devices was that most of the pulsations and shocks never got near the shock absorber. Pulse-Tone puts a flow diversion baffle into the line. Fluid traveling through the hydraulic line bends around the baffle, but pulsation and shock energy waves take the path of least resistance right into the nitrogen precharged bladder. The bladder absorbs up to 98% of the waves’ potentially destructive force. Why Use Pulse-Tones? • improves system efficiency • absorbs hydraulic shocks • very contamination tolerant • very quick response • works well with water, low lubricity fluids Specifications Maximum Operating Pressure – 3000 PSI (207 Bar) Materials • Shell – high strength alloy steel (SA372, 1 gallon & up comply with all ASME material specifications as std.) • Ports – all oil service ports, high strength alloy steel – water and chemical service, 3000 PSI, 304 stainless steel • Poppet & Spring – 304 stainless steel • Gas Valve Cartridge – steel • Gas Valve Protector – steel • Gas Valve Stem – steel • Bladders – Various polymers, see Standard and Optional Bladders in Bladder Accumulators section.

Lab tests show that pump noise levels are increased by 2-3 dB(A) just by adding 12 feet of outlet and return lines. The lines do not generate noise. They radiate noise when they respond to pulsations or vibrations. The pulsations are usually generated by the pump, and the vibrations are radiated by large flat machine surfaces. Not only do hydraulic lines radiate noise, but they frequently provide the primary path for propagating noise from the pump to components that, in turn, react to the noise and radiate additional sound. This helps explain why many pump manufacturers have a very low dB(A) pump rating, but when the pump is installed on a power unit, the sound rating is much higher. It is almost impossible to forecast how much additional sound the hydraulic lines and surrounding structure will radiate. This is why many power units are enclosed after they have been manufactured and installed. The Inline Pulse-Tone reduces pump pulsations and shock. When you stop pulsation and vibration, you stop the cause of component wear and leakage. A power unit with an Inline Pulse-Tone installed can operate at higher RPM with smaller, less expensive components . . . and less noise. NOTE OF INTEREST: An increase of 2.71 dB doubles the intensity noise level. An Inline Pulse-Tone suppressor is located as close to the pump as possible, usually directly at the pump outlet, to stop pulsations and noise before they travel through the piping and radiate off other structural components. As shown in the diagram on the facing page, oil flowing into the Pulse-Tone goes through three different baffles or diffusers. These metal baffles are designed to convert 1/2″ diameter holes to 1/32″ diameter holes. The total radial distance through these baffles is only 1/4″. After passing through these holes, pulsations strike a nitrogen charged rubber bladder. The bladder deflects each time it is hit by a pulsation. This slight deflection of the bladder reduces the shock and noise. The bladder is usually charged with nitrogen to 50% to 60% of the hydraulic operating pressure. The 1/32″ diameter holes in the last baffle are so small that the bladder cannot extrude into them. The large area of the bladder, its ability to oscillate at a high frequency and the short distance each pulsation has to travel once it enters the unit explain the effectiveness of the Pulse-Tone. Why Should You Use the Suppressor? How Does the Work? Selecting a is Easy! No complex sizing formula is required. The Inline Pulse-Tone hydraulic shock suppressor is sized to match your hydraulic line size. There is a unit to fit every pipe and tube size from 3/8″ to 2″ with threaded or flanged connections. Models are available for both 3000 PSI and 5000 PSI hydraulic system pressures.

When ordering, specify the type of connection for each end. Bladder Materials • Standard material is high temperature HNBR, -50° to 300°F (-45° to 149°C) • Fluorocarbon or EPR bladders are available for special applications Precharge The unit can be shipped with a nitrogen precharge equal to 50% of hydraulic system pressure. Check precharge every three months to maintain maximum efficiency (See page 150 for procedures). Mounting The Pulse-Tone may be mounted in any position, horizontal or vertical. Since there are no moving parts, either end may be used for inlet or outlet. Split flange mounting makes it possible to break an existing connection to add the Pulse-Tone between the flanges. 235 psi 25 psi 40 psi 420 psi 5.55 MSEC, 180 HZ 75 psi 12 psi Examples of Pulsation Reduction The examples below show pulsations for pumps at various pressures before and after installation of the Inline Pulse-Tone.
