Technical Information

General Description

The ABV101 Series Accumulator Bleed-Down Valve isused to safely bleed-down an accumulator prior tomaintenance work.

Operation

Pump flow is directed either to the system or theaccumulator. A check valve isolates the pump; andallows accumulator discharge to reach the system. Apilot-to-close check valve remains closed as long asadequate pressure is maintained on the inlet line.Once this pilot pressure drops below the minimum pilotpressure of the CPC101P check valve, the check valveopens allowing the accumulator to vent to tank. A.100″ diameter orifice provides a bleed down toprevent a surge as the accumulator bleeds to tank. Adirect-acting relief valve at the valve’s inlet provides asafe pressure to both the system and the accumulator.

Features

• Built-in cartridge valves for reduced plumbing and ease ofmaintenance

• Two gage ports

• Hardened operating parts for long life

Standard pressure compensator, code "omit"

Function:The standard pressure compensator controls the output flow(displacement, swash plate angle) in a way, that - when the setpressure is reached- the output flow of the pump just covers theflow needed by the system.

As long as the system pressure is below the set pressure - set byadjusting spring preload at the compensator - compensator spoolis moved by the spring in a position, where the servo piston isconnected to the pump case drain port. The servo spring keepsthe pump at full displacement.

When system pressure at pump outlet reaches the set pressurethe compensator spool is moved against the spring into a positionwhere the servo piston gets connected to the pump pressureport. The pressure moves the servo piston against the servospring and reduces the swash plate angle of the pump. Thedisplacement of the pump is reduced to exact the output flowrequired to keep the system pressure on the set level.

When no flow is needed by the system and the set pressure isreached the pump is compensated to deadhead. The displacementonly covers the flow requirements of the pump (leakage of rotatinggroup and compensator pilot flow).

Remote pressure compensator code: "M" (internal pilot supply)FunctionThe remote compensator controls the pressure difference betweensystem (pump output) pressure and the pressure pp. in thecompensator spring chamber. When the standard pressurecompensator compares a spring preload with a pressure, theremote compensator compares a spring preload with a pressuredifference. When system pressure is below set pressure (set atthe remote pilot valve DBV or at the max. pilot valve pmax) the pilotvalve(s) are closed and system pressure p equals spring chamberpressure pp.The spring keeps the compensator spool in a position thatconnects servo piston with pump case drain. The servo springkeeps the pump at full displacement.When system pressure at pump outlet reaches the set pressurethe pilot valve reliefs the spring chamber pressure to the casedrain port and the pressure difference moves the compensatorspool against the spring into a position where the servo piston getsconnected to the pump pressure port. The pressures moves theservo piston against he servo spring and reduces the swash plateangle of the pump. The displacement of the pump is reduced toexact the ouput flow required to keep the system pressure on theset level. When no flow is needed by the system and the setpressure is reached the pump is compensated to deadhead. Thedisplacement only covers the flow requirements of the pump(leakage of rotating group and compensator pilot flow). Theexternal pressure relief valve must be canaple of a minimum flowof 2 l/min. The pilot flow connection is internal via the pilot orificeD. The integrated max. pressure pilot (pmax) is set to the maximumsystem pressure and protects system and pump. In combinationwith one or more pilot valves and one or more directional controlvalves multiple pressure and standby function can be realized.Proportional pilot valves allow electrical proportional pressuresettings.

Fluid Recommendations

Premium quality hydraulic mineral oil fluids arerecommended, like H-LP oils to DIN 51524, part 2. Theviscosity range should be 25 to 50 mm2/s (cSt) at 500 C.Normal operating viscosity range between 12 and 100mm2/s (cSt). Maximum start-up viscositiy is 320 mm2/s. Operating temperature -10 to + 700 C.For other fluids such as phosphoric acid esters consultyour Parker representative for assistance.

Seals

Buna N seals are used for operation with hydraulic fluidsbased on mineral oil. For synthetic fluids, e.g. phosphoricacid esters, Fluorcarbon seals are required. Consultyour Parker representative for assistance.

Filtration

For maximum pump and system componentfunctionability and life, the system should be protectedfrom contamination by effective filtration.Fluid cleanliness should be in accordance with ISOclassification ISO 4406. The quality of filter elementsshould be in accordance with ISO standards.

FiltrationThe functionabillity and life of pumps and other hydrauliccomponents can be improved decisively if the fluidcleanliness corresponds to ISO 4406.

Hydraulic systems to Class 16/13Servo systems to Class 15/12

The quality of filter elements should be in accordance withISO standards.

It is specified to use the Parker off-line and return linefilters, where necessary pressure line filters may be usedas an alternative to the return line filters.

Installation and Mounting

Horizontal mounting:

Outlet port side or top. Inlet port side or bottom, drain portalways uppermost.

Vertical mounting: Shaft pointing upwards.

Install pump and suction line in such a way that themaximum inlet vacuum never exceeds 0,8 bar absolute.The inlet line should be as short and as straight aspossible. A short suction line cut to 450 is recommendedwhen the pump is mounted inside the reservoir, toimprove the inlet conditions. All connections to be leak-free, as air in the suction line will cause cavitation, noise,and damage to the pump.

Drain Line

The drain line must lead directly to the reservoir withoutrestriction. The drain line must not be connected to anyother return line. The end of the drain line must be belowthe lowest fluid level in the reservoir and as far away aspossible from the pump inlet port. This ensures that thepump does not empty itself when not in operation andthat hot aireated oil will not be recirculated. For the samereason, when the pump is mounted inside the reservoir,the drain line should be arranged in such a way that asiphon is created. This ensures that the pump is alwaysfilled with fluid. The drain pressure must not exceed 2bar. Drain line length should not exceed 2 metres.Minimum diameter should be selected according to theport size and a straight low pressure fitting withmaximised bore should be used.

Shaft Rotation and Alignment

Pump and motor shafts must be aligned within 0,25mmT.I.R. maximum. A floating coupling must be used.Bellhousings and couplings can be ordered atmanufacturers listed in this catalogue. Please follow thecoupling manufacturer's installation instructions. Consultyour Parker representative for assistance on radial loadtype drives.

Start Up

Prior to start up, the pump case must be filled withhydraulic fluid (use case drain port). Initial start upshould be at zero pressure with an open circuit to enablethe pump to prime. Pressure should only be increasedonce the pump has been fully primed.

Attention: Check motor rotation direction.

The newly designed closed bottomelements for the RF2 and IL2 modelsinsures all contamination remainstrapped within the element as thefilter is serviced.

A wide variety of visual andelectrical indicators allows you toknow exactly when the element

needs to be serviced. There is even a“no element” indicator that cansense when there is not an elementinstalled in the filter.

From top to bottom, the Moduflowfilter series provides the highlevel of filtration and long termdependability so vital to today’shydraulic systems.

Submersible Option

When there is a limited amount of space on thetop of the reservoir, the Moduflow filter can bemounted in the side of a reservoir.

A check valve mounted on the filter bowlprevents the reservoir from being drainedduring servicing of the element. The only fluiddrained is from the inside of the filter housing.

For return line applications(RF2), the fluidreturning to the reservoir holds the check valveopen. When the system is shut down, thecheck valve closes automatically. In suctionapplications (CF2), the check valve is heldopen by a check rod assembly extending fromthe cover to the check valve at the base of thefilter bowl. When the cover is in place, fluidenters the filter. When the cover is removedfor servicing, the check valve closes.

Longer Life for Your Hydraulic Units .. .The piston-type accumulator offers you many importantadvantages. Its simple, compact, cylindrical design andsturdy construction ensures dependable performance,maximum efficiency and long service life.

Selection — Piston-type accumulators are available in 2"through 12" bore sizes. For the proper size accumulator tomeet your requirements, refer to page 23 for accumulatorsizing data. Additional size selection information and datais available from your local distributor.

Pressure Ratings — Patented V-O ring delivers fullsealing on 3000 psi and 5000 psi units. For pressuresover 5000 psi, consult factory.

For sizes available see “How to Order” on page 12.

Fluids — Accumulators are compatible with a widerange of fluids. The standard accumulator may be usedwith petroleum-based industrial oil or the water-baseflame resistant fluids. Standard temperature range forpistontype accumulators is -20°F to +200°F. Sealscompatible with most industrial fluids can be furnished onspecial orders with temperature ranges from -65°F to+400°F.

Water Service — Suitability is provided by plating allsurfaces and parts.

Seals — Piston-type accumulators using petroleum-based fluids, water-glycol or water-in-oil emulsions maybe used with standard nitrile (Buna-N) seals. Accumula-tors using synthetic, flame resistant fluids require specialseals. When phosphate esters or its blends are used,Viton or EPR seals will be required. Consult your localdistributor for seal and fluid compatibility.

Precharge — Precharge is the initial gas pressure that iscontained by the accumulator prior to the system start-up.For precharge instructions, see Maintenance Bulletin1630M1.

Construction — Piston-type accumulators are designedwith a compact, rugged steel tube and cap. Safety bleedholes in the tube and gas valve are exposed beforedisassembly of the gas cap can be completed, warning ofany gas pressure not relieved in the accumulator.

Sealing at full pressure rating — The piston is carriedon PTFE guide rings, eliminating metal-to-metal contact.Of the many features offered by the piston-type accumu-lator, the most important and unique is its piston sealing,illustrated in the cross section above.

This patented, five-blade V-type O-ring maintains fullcontact between piston and wall without rolling. Thissealing remains effective even under rapid cycling, withoperating pressures at 5000 psi.

The V-O ring also holds full pressure throughout long idleperiods between cycles. As a result, you get moredependable, full pressure storage of hydraulic energy.The V-O ring also ensures safer, more reliable absorptionof sudden pressure peaks in your fluid system.

The piston-type accumulator line also includes models fordesign into original equipment, for laboratory test setupsand for replacements in plant systems. Piston-typeaccumulators can be mounted in any position and can beequipped with many different accessories.

3000 PSI Auxiliary Gas BottlesWhere space will not permit the installation ofa required piston-type accumulator, a smalleraccumulator may often be used by connecting itto an auxiliary gas bottle(s) that can be locatedin some nearby spot where space is available.

In some cases, a piston-type accumulator andgas bottle combination may be lower in totalcost. Piston travel, confined to the accumulator,must be carefully calculated with ample margins.Available auxiliary gas bottle sizes are shown inthe table below.

Hydra-Ride

Capacity and Dimensions

Accumulator Options

Hydra-RideThe Hydra-Ride is basically a cylindrical vessel with aunique floating piston separator between pressurizedgas on one side and the incompressible fluid from thehydraulic circuit on the other, resulting in these benefits:

■ Improved softer ride reduces loss from damage tofragile products

■ Reduced hydraulic shock lowers maintenance costson your trucks

■ Improved lift truck ride reduces operator fatigue

■ Improved efficiency of your material-handling

■ Replacement of seals and alignment rings is easy andinexpensive—just order the repair kit for the modelnumber stamped on the name plate

■ Thoroughly proven design and rugged construction

Safety FusesSafety fuses (thermo fuses) are used as a safety deviceon piston-type accumulators and gas bottles to preventoverpressurizing of the gas due to external heat or hydraulicpressure. The rupture disks are calibrated to rupture at a

pre-determined pressure. Safety fuses are available on allsizes of bladder-type and piston-type accumulators andgas bottles except 1 qt. bladder. When ordering, pleasespecify rupture pressure required.

Note: When ordering, specify housing part number, disk part number andrupture pressure desired. Example: 7560010000/756003-3000 PSI.

Bottom RepairableBladder-Type Accumulator Features

Bladder-type accumulators used in hydraulic systemsperform many different functions, some of which include:

Maintaining Pressure■ Compensating for pressure loss due to leakage, or

pressure increase due to thermal expansion.

■ For holding pressure while pump is doing other work.

■ For emergency use in case of pump or power failure,such as pressurizing clamp on work piece in machinetool, or lift truck clamp carrying a load, or rubber curingand plastics presses, or supplying fluid power to with-draw tools to avoid work spoilage, or to maintain oilpressure on support bearing until turbine can bebrought to a stop.

Absorbing Shock■ Cushioning of valve closure in hydraulic power

systems or fluid transmission lines.

■ Cushioning load start, stop or reversal, as on hones,planers, etc.

■ Cushioning loads being transported, as on lift trucks,tractor shovel loaders, and other material-handlingand earth-moving equipment.

■ Cushioning load reactions, as on head of rockcrusher, or on pressure rolls of papermaking,calendering or printing machines.

ConventionalTop-RepairableBladder-Type Accumulator Features

Features

Options

Supplementlng Pump Delivery

■ On machines with multiple operations where peakdisplacement requirements can be stored in theaccumulator during other portions of the cycle orduring idle periods (on continuous operating cycle,total demand cannot exceed total pump deliveryin cycle time. Operations requiring oil from theaccumulator must be of lower pressures thanrelief valve setting: volume of oil will be small ifoperation requires pressure close to relief setting).

Energy Storage

■ On electric circuit breakers and switchgear.

■ On hydraulic starters for diesel engines.

Dispensing Fluid

■ Such as in a pressurized lubrication system.

Acting as Fluid Barrier■ Where two different fluids are being used in the same

system (bladder compound must be suitable for bothfluids).

Bladder-type accumulators provide excellent gas and fluidseparation and are less sensitive to fluid contamination.Bladders are designed without pleats which can havestress concentrations and cause potential early failure.Bladder-type accumulators are available in top andbottom repairable styles.

The shell is made from a single piece of chromemolybdenumsteel and has a 4 to 1 design factor, at rated pressure.

New "2 piece" valvestem with separategas valve.

Bladder-typeaccumulators providepositive gas and fluidseparation. Bladders donot have pleats or highstress areas that cancause premature failure.

Sizing Accumulators

In selecting the proper accumulator size V1 (size of accumulator in cubic inches) when Vw (volume of fluid to bedischarged from accumulator) is known.

“E” in the above equation adjusts the equation due to the accumulator efficiency versus the gas prechargepressure. Use the following constants:

For Supplementing Pump For Auxilliary Power Source (No Pump)E = 1.24 for bladder accumulators. E = 1.60 for bladder accumulators.E = 1.11 for piston accumulators. E = 1.45 for piston accumulators.

In the above equation the discharge coefficient “d” adjusts the equation for the change in gas temperature dueto heat gains and losses caused by expansion and compression of the gas.

Adiabatic Operation

In an adiabatic operation where the gas temperature is rapidly changing as a result of rapid compressionand expansion of the gas:

d = 1 _ 1/n (See Table 1, Page 22 for “d” Calculations.)

Where:

a = P3 = working pressure ratioP2

P3 = Maximum system pressureP2 = Minimum system pressuren = Polytropic exponent for adiabatic operation (See Charts on Pages 23-24.)

Isothermal OperationIn an isothermal operation where the compression and expansion of the gas is very slow, allowingenough time for heat transfer resulting in little or no change in gas temperature.

d = 1 _

Where:

a = P3 = working pressure ratio

P3 = Maximum system pressureP2 = Minimum system pressure

Problem #2 Increasing Cylinder Speed In An Existing Hydraulic System

Given: Present system has a 6 GPM pump capable of 3000 PSI, 8" bore x 10" stroke cylinder witha 2" rod. Minimum pressure to extend and retract cylinder is 1800 PSI. Gas temperature is150°F. Bladder accumulator to be used. Cylinder cycle time is to be reduced from 42seconds to 12 seconds. Dwell time between cycles is 40 seconds.


P2 = 1800 PSI = Minimum system pressure

Vc = 973.9 in3 = Displacement of actuator per cycle

CT = 12 sec. = Desired cycle time

DT = 40 sec. = Dwell time between cycles

Q = 6 GPM = Present pump flow


Solve For:

Problem #3 Hydraulic Shock Supression

Given: System has a 100 GPM pump operating at 2500 PSI. Shock is caused by a rapidly closingdirectional valve. 80 feet of pipe is between pump and valve causing shock. Internal area ofpipe is 1.4 square inches. Gas operating temperature is 100°F. Use standard petroleum oil(54.3 lbs/ft3). What size accumulator (V1) would be required to limit shock pressure to10% above system pressure P

2?


L = 80 ft. = Length of pipe between pump and valve causing shock.

A = 1.4 in2 = Internal area of pipe

P2

= 2500 PSI = Operating pressure

Q = 100 GPM = Rate of flow


Solve For:

n = 188 = Discharge coefficient — See Page 22. Use 0-8 second curves.

VT = 0.78 ft3 = (L) (A) = Total volume of oil in pipe 144

WT = 54.3 lbs/ft3 = Weight of fluid per cubic feet

W = 42.2 lbs = (VT) (WT) = Total weight of liquid in pipe

V = 22.9 ft/sec. = (.3208)(Q)

A= Flow velocity

C3 = .0464 = From Page 22 (Table II)

(Opposite the “n” value selected)

Solution :

V1 (in3) = Size accumulator required

V1 = (V)2(W) (n-1) (.205)

(P2) (C3)

V1 = (22.9)2 (42.2) (1.88-1) (.205) = 34.4 in3 A 1 Qt. accumulator would satisfy the circuit.

(2500) (.0464)

P1 gas precharge pressure should normally be 60% of P

*Safety Note:In any accumulator circuit, a means should be availableof automatically unloading the accumulator when themachine is shut down. Such a valve could be located atthis point in the circuit.

Control of Usable VolumeThe usable volume of an accumulator should be dis-charged at a controlled rate. If an accumulator is requiredto maintain system pressure, this controlled rate isautomatically achieved by the leakage fluid it has toreplace. However, an accumulator which is used todevelop a pressurized flow can discharge its usablevolume too rapidly as a downstream directional valve isshifted. For this reason, accumulators in this applicationare often equipped with a flow control and bypass checkat their inlet-outlet port.

Pump Unloading in Accumulator CircuitsTo keep a pump/electric motor fully unloaded until it isrequired to re-charge an accumulator, an electricpressure switch can be used.

In the circuit illustrated, a pressure switch sensesaccumulator pressure sending and cutting-out electricalsignals at various pressure levels. The electrical signalsare transmitted to a normally-open, solenoid operated2-way valve which vents and de-vents a pilot operatedrelief valve. When the accumulator is being charged, thepressure switch sends an electrical signal to the 2-wayvalve solenoid. With the accumulator charged, thepressure switch cuts out the signal, venting the relief valveand unloading pump/electric motor. The setting of thepressure switch determines the pressure range withinwhich a pump/electric motor works.

Using a pressure switch to vent a relief valve results in apump/electric motor being fully unloaded when systemconditions dictate.

In the circuit illustrated, an unloading valve is used todump a flow back to tank once an accumulator is chargedto the unloading valve setting.

Once the valve closes, pump/electric motor must there-fore generate power to recharge the accumulator to theunloading valve setting.

Differential Unloading Relief ValveInstead of using a pressure switch and solenoid valve tovent a relief valve while an accumulator is charged, onehydraulic component can be used — a differentialunloading relief valve.

A differential unloading relief valve is specifically designedfor use with accumulators. As its name implies, the valveunloads a pump/electric motor over a differential pressurerange.

A differential unloading relief valve consists of a pilotoperated relief valve, check valve, and differential piston inone valve body. The valve body includes pump, tank, andaccumulator passages.

Maintaining PressureAccumulators are used to maintain pressure. This can berequired in one leg of a circuit while pump/electric motoris delivering flow to another portion of the system.

In the circuit illustrated, two clamp cylinders are required tohold a part in place. As the directional valves are shifted,both cylinders extend the clamp at the pump’s compensatorsetting. During this time, the accumulator is charged to thesetting also.

System demands require that cylinder B maintain pressurewhile cylinder A retracts. As directional valve A is shifted,pressure at the pump, as well as in line A, drops quite low.Pressure at cylinder B is maintained because the accumu-lator has stored sufficient fluid under pressure to make upfor any leakage in line B.

Accumulators not only maintain pressure by compensatingfor pressure loss due to leakage, but they also compensatefor pressure increase due to thermal fluid expansion orexternal mechanical forces acting on a cylinder.

In the illustrated circuit, assume that the cylinder is oper-ating near a furnace where ambient temperatures are quitehigh. This causes the fluid to expand. With an accumulatorin the circuit, the excess volume is taken up, keeping thepressure relatively constant. Without an accumulator,pressure in the line would rise uncontrollably and maycause a component housing, fitting, or conductor to crack.

The same situation can also occur if an external mechanicalforce acts to retract the cylinder. Assume now that thecylinder is clamping a curing press. As curing occurs, heatwithin the press causes it to expand resulting in a forceacting to retract the piston rod. The accumulator once againabsorbs the additional volume, maintaining the pressure ata relatively constant level.

*Safety Note:In any accumulator circuit, a means should be available forautomatically unloading the accumulator when the machineis shut down. Such a valve could be located at this point inthe circuit.

Absorbing ShockHydro-pneumatic accumulators are sometimes used toabsorb system shock even though in this application theyare difficult to properly design into a system.

Shock in a hydraulic system may be developed from theinertia of a load attached to a cylinder or motor. Or, it maybe caused by fluid inertia when system flow is suddenlyblocked or changed direction as a directional valve isshifted quickly. An accumulator in the circuit will absorbsome of the shock and not allow it to be transmitted fullythroughout the system.

Shock may also occur in a hydraulic system due toextemal mechanical forces. In the circuit illustrated, theload attached to the cylinder has a tendency to bouncecausing the rod to be pushed in and shock generated.An accumulator positioned in the cylinder line can helpreduce the shock effects.

Developing FlowSince charged accumulators are a source of hydraulicpotential energy, stored energy of an accumulator can beused to develop system flow when system demand isgreater than pump delivery. For instance, if a machine isdesigned to cycle infrequently, a small displacementpump can be used to fill an accumulator over a period oftime. When the moment arrives for the machine tooperate, a directional valve is shifted downstream andthe accumulator delivers the required pressurized flow toan actuator.

Using an accumulator in combination with a small pumpin this manner conserves peak horsepower. For insteadof using a large pump/electric motor to generate a largehorsepower all at once, the work can be evenly spreadover a time period with a small pump/electric motor.

*Safety Note:

In any accumulator circuit, a means should be availablefor automatically unloading the accumulator when themachine is shut down. Such a valve could be located atthis point in the circuit.

Maintenance Instructions For

Hydraulic PistonAccumulatorsInstallationMost accumulators shipped from the factory willnot be pre-charged. However, in some cases theywill be shipped with some amount of nitrogencharge, the value of which will be stamped on thenameplate.

Keep the hydraulic port covered to keep outforeign material until ready to make the hydraulicconnections.

The accumulator can be mounted in anyorientation. However, it should be rigidly mountedusing any combination of the mounting holesprovided at the hydraulic cap or proper clamps.The hydraulic circuit, which contains a connectionto the accumulator should be designed so that itautomatically discharges all hydraulic fluid fromthe accumulator when the equipment is turned off.

Pre-ChargingUse an inert gas such as nitrogen for pre-chargingaccumulators.If water pumped nitrogen is not available, oil-pumpednitrogen may be used. (C.G.A. standards: Nitrogen gasbottles for water pumped nitrogen has a right-hand valvethread which requires charging and gauging assembly1445950000 for units up to 3000 psi. Oil-pumped nitrogenrequires a left-handed valve thread (use 1445960000).For accumulators rated over 3000 psi up to 5000 psi, useassembly #1449120000 (see Figure 3).

If equipment other than the above listed is used, makesure it is compatible with the gas valve assembly.Nitrogen source and all components must be rated fora pressure at least as high as the nitrogen source. It isstrongly recommended that the nitrogen bottle usedhave a high pressure regulator.

Make sure nitrogen supply is shut off. Attach hose tonitrogen bottle. If accumulator has a gas valve as shownin Figure 5 follow steps A through J and skip steps AAthrough HH. If accumulator has a gas valve as shown inFigure 6, skip steps A through J and follow steps AAthrough HH.

Accumulator having gas valve as per Figure 5.(A) Remove gas valve guard and gas valve cap.(B) Back gas chuck “T” handle all the way out

(counter clockwise) before attaching chargingassembly to accumulator gas valve.

(C) Close bleed valve.(D) Making sure not to loop or twist the hose, attach

swivel nut to gas valve and tighten (10-15 in. lb.)(11.5-17 cm kg).

(E) Turn gas chuck “T” handle all the way down. Thiswill depress core in gas valve.

(F) Crack open nitrogen bottle valve and slowly fillaccumulator. Shut off when gage indicatesdesired pre-charge.

(G) Let the pre-charge set for 10 to 15 minutes. Thiswill allow the gas temperature to stabilize. If thedesired pre-charge is exceeded, close nitrogenbottle valve, then slowly open bleed valve(Figure 1). Do not reduce pre-charge bydepressing valve core with a foreign object.High pressure may rupture rubber valve seat.

(H) When finished pre-charging accumulator, turn “T”handle all the way out on gas chuck (Figure 1),then open bleed valve.

(I) Hold gas valve to keep from turning, loosenswivel nut, remove assembly.

(J) Replace gas valve cap (10-15 in. lbs.) (11.5-17 cmkg) and valve guard. (Gas valve cap serves as asecondary seal.)

Accumulator having gas valve as per Figure 6.(AA) Remove gas valve guard and gas valve cap.(BB) Close bleed valve and, making sure not to loop

Maint enanceRepair Kits (see Parts List) are available for allaccumulator models. When ordering repair kits, statecomplete model number from nameplate. Also specifyfluid and temperature at which used.

Occasional replacement of v-o-ring seal on the piston isgenerally the only maintenance required. Replacementof other seals on end caps and gas valve is recom-mended (see Kit Numbers).

Periodic checking of pre-charge pressure will detectwhether v-o-ring wear is sufficient to begin reducingsealing performance. If pre-charge is low, also check forgas valve and/or end seal leakage. Allowing for tem-perature difference, if any, from time of its pressurechecking, pre-charge pressure will rise if oil gathers inthe gas side and will fall if gas leaks into the oil side orout past gas end seals. It is suggested that a check bemade a week after installation, and thereafter once amonth.

Pre-charge Checking ProcedureUsing appropriate valve in the hydraulic system,discharge all oil from accumulator and allow piston tobottom against hydraulic end cap.

For accumulators rated for 3000 psi or less, use gagingassembly as shown in Figure 2 (Part #0851220000). Foraccumulators rated over 3000 psi up to 5000 psi, useassembly as shown in Figure 4 (Part #1449610000).

Accumulators having gas valve as per Figure 5. (1) Remove gas valve guard and gas valve cap. (2) Back gas chuck “T” handle all the way out (counter

clockwise) before attaching charging assembly toaccumulator gas valve.

(3) Close bleed valve. (4) Attach swivel nut to gas valve and tighten

(10-15 in. lb.) (11.5-17 cm kg). (5) Turn gas chuck “T” handle all the way down. This

will depress core in gas valve and check pressure. (6) To remove gaging assembly turn “T” handle all the

way out on gas chuck (Figure 1), then open bleedvalve.

(7) Hold gas valve from turning, loosen swivel nut,remove assembly.

(8) Replace gas valve cap (10-15 in. lbs.) (11.5-17 cmkg) and valve guard.

Accumulators having gas valve as per Figure 6. (9) Remove gas valve guard and gas valve cap.(10) Close bleed valve.(11) Attach swivel nut to gas valve and tighten

(10-15 in. lb.) (11.5-17 cm kg).(12) Hold gas valve at point “C” with one (1) wrench

while unscrewing hex nut at point “D” with asecond wrench. This will open the poppet insidethe gas valve. Turn 2-3 times and read pre-charge.

(13) With a wrench, tighten hex nut at point “D” to closeinternal poppet (5-8 ft. lbs.) (5.7-9.2 cm kg).

(14) Hold gas valve at point “C” with wrench andremove swivel nut assembly.

(15) Replace gas cap and tighten (10-15 in. lb.)(11.5-17 cm kg), and install gas valve guard.

Remove from Hydraulic SystemShut equipment down and make certain that hydraulicpressure at the accumulator is at zero. At this point thepiston will be bottomed at the hydraulic end.

For accumulators having gas valve as shown in Figure 5,attach gaging assembly as shown in Figure 2 followingSteps 1 through 5. Then, open bleed valve until all gaspre-charge is relieved from accumulator. Then removegaging assembly and gas valve.

For accumulators having gas valve as shown in Figure 6,remove gas valve guard and gas valve cap. Then holdvalve at point “C” with one (1) wrench while unscrewinghex nut at point “D” with a second wrench. Wait until allgas pre-charge is relieved from the accumulator andthen remove gas valve.

Remove accumulator from hydraulic system. Threadedholes in hydraulic cap may be used as a means ofattachment for lifting, or use a sling around the body.

Disassembly of AccumulatorLay the accumulator horizontal and hold down with astrap wrench or in a vise. Some accumulators may haveboth end caps threaded into the body and some unitsmay only have the gas cap threaded into the body. INBOTH CASES ALWAYS REMOVE THE GAS CAPFIRST (end cap which contained gas valve). To removecap or caps, install three (3) pins into the holes in thecap, then, using a long bar working against the pins,unthread the cap from the body. Remove o-rings andback-up rings from end cap.

Remove piston by pushing from hydraulic end with abar. NEVER TRY TO REMOVE PISTON BY APPLYINGCOMPRESSED AIR AT OPPOSITE END. To removev-o-ring from piston, lift seal with small smooth screwdriver or similar tool, moving the tool around the pistonseveral times while using the other hand to work ring offthe piston.

CleaningThoroughly clean metal parts in solvent and dry withcompressed air. Clean bore of body with a clean, lint-free cloth soaked in clean solvent. Bore must be cleanof any visible particles or particles detectable to touch.

InspectionInspect piston for cracks, burrs around o-ring grooves,or damage. Examine body bore, using a light, forscratches or scoring. Inspect end caps for damagedthreads or burrs on o-ring grooves.

Repair and ReplacementMinor nicks, scratches or light scoring of the body borecan be removed by using crocus cloth. Dress bore untilall apparent imperfections have been removed. ReplacePTFE wear rings, v-o-rings, o-rings and their respectiveback up washers if the original assembly contained them.

35


ReassemblyCoat all internal parts with clean hydraulic fluid beforereassembly.

With new v-o-ring and PTFE rings on piston, installpiston, hollow side toward gas end, in bore of body. Donot let v-o-ring drag on threads. Piston must go intobore exactly square and very slowly. (V-o-ring willcompress as it rides up the chamfer if done slowly, butmay be damaged if forced quickly.) Piston will fit snug.Use hammer and wood block to tap piston into placeuntil all of piston is 2 inches below beginning of honedbore. Keep force against piston while tapping v-o-ringthrough the bore chamfer, otherwise piston will bounceback, damaging the o-ring. Cover port opening to keepout dirt.

Install new back-up ring first, then a new o-ring onthreaded end cap or caps and install into body bore.Care should be exercised not to drag o-ring overthreads. End cap will stop against chamfer leading intohoned bore (extreme tightness not required — o-ringsealing is not dependent upon cap tightness).

Maintenance Instructions For

Parker Series “AB”Bladder Accumulators

InstallationMost accumulators shipped from the factory will havesome amount of pre-charge. It may vary from 50 psito several hundred psi.

Keep the hydraulic port covered to keep out foreignmaterial until ready to make the hydraulic connection.

The accumulator should be mounted within 25° ofvertical. It should also be rigidly mounted usingappropriate mounting hardware, which is shown inthe accumulator catalog. The hydraulic circuit, whichcontains a connection to the accumulator, should bedesigned so that it automatically discharges allhydraulic fluid from the accumulator when theequipment is turned off.

Pre-ChargingUse only an inert gas such as nitrogen for pre-chargingaccumulator. If possible, use water pumped nitrogen (gasbottle will have a right-hand thread). Oil pumped nitrogen maybe used, however, gas bottle will have left-hand thread.

It is recommended to use pre-charging and gaging assemblyas shown in Figure 1 (Part #1445950000, right-hand thread;Part #1445960000, left-hand thread), and in Figure 2 Part#0871000000 for 1-15 gallon & Part #0871020000 for 10-150cu. in. accumulator rated for 3,000 psi or less. For accumula-tors rated for 5,000 psi, as well as the 25-40 gallon, 3,000 psiaccumulatorrs, use assembly shown in Figure 6 (Part#1449120000). If other equipment is used, make sure it iscompatible with the gas valve assembly and nitrogen source.All components must be rated for a pressure at least as highas the nitrogen source. It is strongly recommended that thenitrogen bottle used have a high pressure regulator.

Make sure nitrogen supply is shut off. Attach hose to nitrogenbottle. If accumulator has a gas valve as shown in Figure 8A or8B, follow steps A through J and skip steps AA through HH. Ifaccumulator has a gas valve as shown in Figure 9, skip stepsA through J and follow steps AA through HH.

Accumulators having gas valve per Figure 8A or 8B

(A) Remove gas valve guard and if installed remove gasvalve cap.

(B) Back gas chuck “T” handle all the way out (counterclockwise) before attaching charging assembly toaccumulator gas valve.

(C) Close bleed valve.

(D) Making sure not to loop or twist the hose, attach swivelnut to gas valve and tighten (10-15 in. lb.) (11.5-17 cm kg).

NOTE: For top repairable units having valves as shown inFigure 8B, a valve extension as shown in Figure 3 must beattached to the gas valve after removing valve cap.

(E) Turn gas chuck “T” handle all the way down. This willdepress core in gas valve.

(F) Crack open nitrogen bottle or regulator valve and slowlyfill accumulator. Caution: if the pre-charge is not doneslowly, the bladder may suffer permanent damage. Shutoff when gage indicates desired pre-charge. (Note: it isrecommended that pre-charge pressure be at least 25%of maximum system pressure.) Damage to bladder mayoccur if this ratio is not maintained or exceeded. Forshock suppression applications, pre-charge is usually setat about 65% of system pressure. When the accumulatoris used to supplement pump flow, auxiliary power supplyor leakage compensation, pre-charge is usually set atapproximately 80% of minimum system pressure.

(G) Let the pre-charge set for 10 to 15 minutes. This willallow the gas temperature to stabilize. If the desired pre-charge is exceeded, close nitrogen bottle valve, thenslowly open bleed valve until desired pressure is reached(Figure 1). Do not reduce pre-charge by depressing valvecore. High pressure may rupture rubber valve seat.

(H) When finished pre-charging accumulator, turn “T” handleall the way out on gas chuck (Figure 1), then open bleedvalve.

(I) Hold gas valve from turning, loosen swivel nut, removeassembly.

(J) Install gas valve cap if part of assembly (10-15 in. lbs.)(11.5-17 cm kg) and valve guard.

Accumulators having gas valve per Figure 9

(AA) Remove gas valve guard and gas valve cap.

(BB) Close bleed valve and make sure not to loop or twistthe hose, attach swivel nut to gas valve and tighten(10-15 in. lb.) (11.5-17 cm kg).

(CC) Hold gas valve at point “C” with one (1) wrench whileunscrewing hex nut at point “D” with a second wrench.This will open the poppet inside the gas valve. Notethat (4) turns will fully open the valve.

(DD) Crack open nitrogen bottle or regulator valve andslowly fill accumulator. Caution: if the pre-charge isnot done slowly, the bladder may suffer permanentdamage. Shut off when gage indicates desired pre-charge. (Note: it is recommended that pre-chargepressure be at least 25% of maximum system pres-sure.) Damage to bladder may occur if this ratio isnot maintained or exceeded. For shock suppressionapplications, pre-charge is usually set at about 65% ofsystem pressure. When the accumulator is used tosupplement pump flow, auxiliary power supply orleakage compensation, pre-charge is usually set atapproximately 80% of minimum system pressure.

(EE) Let the pre-charge set for 10 to 15 minutes. This willallow the gas temperature to stabilize. If the desiredpre-charge is exceeded, close nitrogen bottle valve,then slowly open bleed valve until desired pre-chargeis reached (Figure 6).

(FF) With a wrench, tighten hex nut at point “D” to closeinternal poppet (10-15 in. lbs.) (11.5-17 cm kg).

(GG) Hold gas valve at point “C” with wrench and removecharging and gauging assembly.
