3 Introduction Accumulators provide a means of regulating the performance of a hydraulic system. They are suitable for storing energy under pressure, absorbing hydraulic shock, dampening pump pulsation and fl ow fl uctuations. Bladder or diaphragm accumulators provide excellent gas and fl uid separation ensuring dependable performance, maximum effi ciency, and long service life. Why use an Accumulator? Improves your system effi ciency Supplements your pump fl ow Supplies extra power in an emergency Compensates for any system leakage Absorbs hydraulic shocks Accepted world wide High/ low temperature tolerance Extremely safe (cannot be disassembled under pressure) Quick response Wide range of compounds for a variety of fl uids Accumulator Function The design of the Stauff accumulator makes use of the difference in the compressibility between a gas (nitrogen) and a liquid (hydraulic fl uids). The bladder contained in the shell is pre-charged with nitrogen gas to a pressure determined by the system pressure. After pre-charging, the work can be split into three steps. Step 1. Step 2. Step 3. When the hydraulic fl uid enters the accumulator, the nitrogen contained in the bladder is compressed and its pressure is increased. The compression of the bladder stops when the pressure of the fl uid and nitrogen are equal (balanced). During this step the bladder is not subject to any abnormal mechanical stress. On demand, as system pressure falls, the accumulator s stored fl uid is returned to the system under pressure applied by the compressed nitrogen. On completion of the hydraulic system functions, the accumulator reverts to step 1. 3

13 Charging Kit #STA-CK-1 To maintain optimum performance in hydraulic systems employing accumulators, it is recommended that the gas pre-charge pressure be checked regularly. A loss in the gas pre-charge pressure will cause a drop in the system effi ciency and may cause damage to the accumulator bladder, diaphragm or piston. The charging kit allows hydro-pneumatic accumulators, whether bladder type, diaphragm type or piston type, to be charged with nitrogen to the desired pressure. For this purpose, the kit is connected to a commercially available nitrogen cylinder by a fl exible hose. The kit can also be used by technicians to check the current gas pre-charge pressure. The control valve incorporates a pressure gauge to permit direct pressure readings as well as a check valve to prevent back fl ow in the case of low pressures in the nitrogen cylinder. A manual bleed valve allows excess pressure to be reduced to the desired operating pre-charge level. - Pressure gauge is a safety pattern type to AS The kit has adaptors to connect the hose to the nitrogen cylinder as well as adaptors to connect the control valve to the accumulator. 1 Order Code Description 1 STA -CK -1 Accumulator Charge Kit Comprising of: 2 SAA x 32 TPI adaptor 3 SAA UNF adaptor 4 SAA50510 ¼ ISO 228 adaptor 5 SAAGAS531 Type 50 - ¼ BSPT bottle adaptor 6 SAA2069 Valve 7 SAA2069T Valve tool 8 SAAPC2156/250 Charging/pre - loading/gauge set, BAR 9 SMS20/B ¼-2000BGAS Hose assembly - 2m - Optional: kpa outlet nitrogen regulator.

14 Precharging Procedure General Information Prior to commissioning a hydraulic system, any accumulators in the system should have their pre-charge pressure checked and adjusted. The condition of the accumulator is primarily determined by periodic checking of the pre-charge pressure. Hydraulic Accumulators are pressure vessels and only qualified personnel should perform maintenance. Drain all fluid completely from accumulator before performing any maintenance. DO NOT weld or braze directly on accumulator shell. DO NOT use automotive type valve cores as high pressure accumulator gas valves. The most accurate pre-charge readings can only be taken when fluid pressure is at zero. Always observe the maximum working pressure and operating temperature ranges. Pre-charging Bladder Accumulators A B C D Isolate the accumulator from the system, open the drain valve and make sure hydraulic fluid pressure is zero. Remove gas valve protection cap and valve cap from the accumulator. To charge the accumulator, use a charging hose and gauge assembly from the Stauff Charging Kit # STA-CK-1 rated for 250 bar maximum. Before using the charging assembly (Figure 1.) make sure that valve A is completely open (counter-clockwise), and that bleed valve B (Figure 1.) is closed. E Connect the charging unit to the gas fill valve on the accumulator by means of knurled cap D (Figure 1.). F G H I J K L M N O P Fit the gas bottle adaptor (included in Stauff charging kit) to the nitrogen bottle, make sure that the gas valve on the nitrogen bottle is closed (see Figure 2.) then attach gas hose to the gas bottle adaptor on the nitrogen bottle. Connect the other end of gas hose to the Stauff test coupling C (Figure 1.), after taking off its cap. Turn valve A (Figure 1.) clockwise to the point where resistance is felt or pressure is registered on the gauge(only if there is an existing pre-charge). SLOWLY open valve on nitrogen bottle (Figure 2.) and allow the gas to flow to the accumulator. When the pressure in the accumulator is slightly higher than is required, close the valve on the nitrogen bottle. Open valve A (Figure 1.) (counter-clockwise) and reduce the pressure in the gas hose and charging assembly to zero by means of bleed valve B (Figure 1.). Remove hose from non-return Stauff test coupling C (Figure 1.) and replace cap. Close the bleed valve B (Figure 1.) and wait a few minutes for pressure to stabilise. Screw valve A (Figure 1.) clockwise until pressure can be read on gauge. This should be slightly higher than the required pressure. Adjust pressure by means of bleed valve B (Figure 1.), then unscrew valve A (Figure 1.), counterclockwise. Open valve B (figure 1) then remove charging unit. Replace gas valve cap and protective cap on accumulator. Accumulator is now ready for use. B A C - Safety pattern gauge. D Figure 1 Figure 2 NOTE: Allow accumulator to rest about minutes after gas pre-charging. This will allow gas temperature to adjust and equalise. Recheck gas pre-charge pressure and adjust if necessary. Check accumulator gas valve for any leaks with soapy water. Always wear safety glasses. 14

15 Maintenance General Information The condition of the accumulator is primarily determined by periodic checking of gas pre-charge pressure. Only qualified personnel should perform any maintenance on accumulators. Nitrogen gas pre-charge pressure should be checked at least once during the first week of operation to ensure that no leak has developed. The pre-charge pressure and ambient temperature should be recorded at installation and checking done at the same temperature if possible. If there is no loss of gas pre-charge pressure, it should be rechecked in approximately 4 months. Thereafter, it should be checked annually. Check pre-charge if the system is acting sluggishly. If pre-charge is low, check gas valve for leakage and recharge. Bladder Accumulators 1 Use appropriate valving in the hydraulic system to discharge all hydraulic fluid from accumulator. 2 To check or adjust pre-charge pressure, HYDRAULIC PRESSURE MUST BE REDUCED TO ZERO. Pre-charge pressure should be checked periodically. 3 Charging and checking should be done with an accumulator charge kit similar to Stauff Part # STA-CK-1. 4 Remove gas valve protection cap and valve cap as per pre-charge procedure instructions (B) on page 14 5 Attach gauge assembly to accumulator gas valve. 6 Make sure bleed valve B (Figure 1.) is closed, depress gas valve core gently by turning valve A (Figure 1.) clockwise. Gas pressure can now be read on gauge. 7 To reduce pressure, open bleed valve B (Figure 1.) carefully, allowing gas to escape until desired pressure is obtained. It the pre-charging pressure is less than required, refer to the pre-charging procedure on page 14 B A C - Safety pattern gauge. According to AS D Figure 1 NOTE: Allow accumulator to rest about minutes after gas pre-charging. This will allow gas temperature to adjust and equalise. Recheck gas pressure and adjust if necessary. Check accumulator gas valve for any leaks with soapy water. The kit has adaptors to connect the hose to the nitrogen cylinder as well as adaptors to connect the charging/pre-loading/gauge set to the accumulator. - Stauff recommend the use of nitrogen gas only for pre-charging of accumulators. - Always wear protective safety glasses. 15

16 Installation Prior to any installation, it is necessary to visually check the accumulator in order to detect any possible damage incurred during transport. For optimal operation, the accumulator needs to be located as close as possible to the application. It may be installed vertically (gas valve facing up), or horizontallly. Avoid standing in the alignment of the connections. Consider the environmental conditions and if needed, protect the accumulator against heat sources, electrical and magnetic fields, lightning strikes, humidity and foul weather Keep 200mm over the top of the gas valve free of encumbrance to allow the use of a charging head Allow free access to the oil drain Keep all markings visible Install in such a way so as to prevent any undue stress on the pipework, either directly or indirectly Clamp the accumulator tightly to a fixed support or alternatively guard it to limit its displacement in case of a connection failure to the hydraulic system Connect the accumulator to the hydraulic system using the right connectors or flanges Check the compatibility of the fluid with the materials used Ensure that the maximum design pressure of the accumulator exceeds the maximum system pressure Ensure that pressure and temperature limits are not exceeded Equip the hydraulic system with a pressure relief device If necessary, add-on a burst disk to account for risks of over pressure associated with thermodynamic effects Install an appropriate Stauff filtration unit and/or organise regular internal inspections as often as is necessary when dealing with abrasive fluids It is strictly forbidden to: Weld, screw or rivet anything onto the accumulator body Operate in any way that may alter the mechanical properties of the accumulator Use the accumulator for construction purposes. (No stress or loading) Modify the accumulator without prior approval from the manufacturer Use any other gas than nitrogen for precharging Commissioning Refer to commissioning instructions supplied with the accumulator.
