When an accumulator is used for volume purposes, such as to apply a brake in the event of a power failure, to supplement the output of a pump, or to maintain a constant system pressure, most manufacturers recommend a bladder accumulator be pre-charged to 80 percent of the minimum acceptable pressure and a piston accumulator to 100 pounds per square inch (psi) below minimum pressure. Most facilities have several of them, but they often are misunderstood. C |lv }9%*w?L].1t>m;s&y.>I:=ujuiSw:M{vOgo}7\B;vN^vu{\1sT] Most accumulators are the bladder, piston or diaphragm type. 0000043943 00000 n We recommend a nitrogen regulator to anyone precharging an accumulator. Most accumulators have a dump valve that can be opened to drain oil to the tank. These charging and gauging units allow hydro-pneumatic accumulators to be charged with dry nitrogen. Operating and installation instructions are included with each charging kit. It is highly recommended that a N2 gas regulator be used while charging any accumulator. Which function it will perform depends upon its pre-charge.

High pressure air controls (HP regulator, relief valve, inlet & regulated outlet gauges and on/off valve), Maximum outlet pressure: 6000, 7500, or 10000 psi. Over time, oil will bypass across the piston seals, displacing nitrogen at the top.

The kit includes different adaptors for accumulator connections which can differ depending on the country and nitrogen gas bottle design. They can also accommodate for lost pressure if the system's pump fails or there is fluid loss in the system.

Our unit ensures maximum outlet pressure will be maintained even if the pressure in the nitrogen cylinders drops as low as 500 psi. If there are any breaches, the shell should be discarded and replaced. Many options are available including pressure gauges, adaptors, connectors, and special nitrogen hoses. We recommend the use of a liquid-filled gauge for high-cycle shock applications. top of the shell and become or excessive wear of To maintain system performance, it is recommended that the gas precharge pressure in your accumulators be checked regularly. In addition to uneven bladder wear, fluid can become trapped away from the outlet if a cavity forms between the bladder and the shell. 0000015040 00000 n causing fluid to become trapped. A charging rig should be 0000002726 00000 n Ensure all accumulator pressure has been removed before beginning installation. 0000004753 00000 n Accumulator gas valve must be removed prior to installation. Do not use on accumulators with a pressure higher than 3000 PSI. When the system is shut down, if the gauge drops immediately to 0 psi without gradually dropping first, it is likely that the gauge is isolated from the accumulator, and whether the accumulator has dumped will be unknown. $245.00. Other pressures and metric gauge markings are also available. Something went wrong. Too low of a pre-charge (or an increase in system pressure without a compensating increase in the pre-charge) can also lead to operating problems, such as reduced speed and stalls. If compressed air is not available, the booster can also be driven directly by the nitrogen cylinders. Fluid Power World covers pneumatics, mobile hydraulics and industrial hydraulics. Follow any recommendations from the original equipment manufacturer (OEM), if they are available. 0000014286 00000 n We stock several different types of nitrogen regulatorscompatible with our accumulators.

If oil never stops coming out of the bleeder valve, the piston is badly worn and must be replaced. Hydraulic Accumulator Charging Kits. Woodhatch Road If you Buy It Now, you'll only be purchasing this item. 0000093401 00000 n The high pressure section of the booster is cooled by the drive exhaust gas and requires no lubrication.

In general, it is better to undercharge than overcharge.

When an accumulator is used for shock absorption, it is not desirable that there be much, if any, oil in the accumulator during operation. A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock.

0000030335 00000 n Only digits are allowed. The next most plentiful inert gas is argon, which makes up less than 1 percent of the earths atmosphere. displacing nitrogen.

The accumulator thus will supplement the pump during portions of the cycle when the system demands more flow than the pump can provide. An accumulator should bear a safety sticker that warns against pre-charging with any gas but nitrogen. The accumulator will respond more rapidly to pressure spikes if the compression process has already begun. It may even result in accumulator damage.

If compressed oxygen or air encounters even a small amount of any hydrocarbon, it can react violently, resulting in an explosion, fire, injury to personnel and property damage. The pre-charge should be performed with no oil in the accumulator. Finally, never attempt to repair an accumulator shell. Seller assumes all responsibility for this listing.

Accumulators, Inc. nitrogen gas boosters are designed to boost gas pressure directly from nitrogen cylinders to outlet pressures as high as 10000 psi. Mounting a piston accumulator horizontally will cause more rapid wear of the piston seals. 0000006201 00000 n These charging kits an indispensable instrument for checking, adjusting or filling nitrogen (N2) into most of the hydraulic accumulators available on the market. A loss in the gas precharge pressure will cause a drop in the system efficiency and could cause damage to the accumulator bladder, diaphragm, or piston.
