AI-CG6-6KT-SS is rated to 6000 PSI maximum working pressure. 
All hydraulic accumulators require charging before first use and need to be monitored and recharged as needed over the life of the accumulator. The system can then be shut down, the dump valve opened to drain oil from the bottom, and the pre-charge restored, recovering the accumulators diminished capacity. When this is the case, pre-charging to 50 percent of the maximum system pressure usually yields an acceptable result. Bladder accumulators can also be damaged if they are mounted horizontally. RH1 5JJ. Under no circumstances should an accumulator be pre-charged with oxygen or air. the bladder may be pushed to the
We recommend a nitrogen regulator to anyone precharging an accumulator. For assistance determining the appropriate accumulator size for your application, please contact us. High pressure hose of different length with adapters for nitrogen bottles from various countries (specify country), at each end with a female swivel coupling G1/4 for connecting to the inflation port, Options include different pressure ranges, adaptors and connectors to suit the most commonly used accumulators available on the market, Supplied in a foam filled plastic carry case for added protection and portability, A complete kit for the control and adjustment of nitrogen pre-charge in accumulators, Offers a safe solution for accumulator maintenance, Maximum working pressure: limited by the maximum operating pressure of the installed hydraulic system, pressure limited to 400 bar in any case, Universal tester and pressurizer (end M28 x 1.50), Connection adapters for inflation valves (7/8 5/8 8V1 -M28 x 1.50 G 1/4), High-pressure hose, 2.5 m long, for connecting to a nitrogen source, Operating instruction in French, English, German & Italian. may hit the poppet assembly,

Over time, oil will bypass across the piston seals, displacing nitrogen at the top. Finally, never attempt to repair an accumulator shell. The accumulator thus will supplement the pump during portions of the cycle when the system demands more flow than the pump can provide. A charging rig should be

$245.00. Hydraulic accumulators store pressurized hydraulic fluid and release it as needed to maintain steady pump flow and pressure, dampen vibrations and shocks, and compensate for leaks or thermal expansion in the system. To maintain system performance, it is recommended that the gas precharge pressure in your accumulators be checked regularly.

West Valley City, Which function it will perform depends upon its pre-charge. 
If the pre-charge is too low, the charging rig comes with a hose to connect it to a nitrogen bottle. H\n0z The regulator ensures that nitrogen is added to your accumulator at a safe rate, which protects the bladder from damage as well as keeps the air temperature inside your accumulator from rising during compression. When oil stops coming out, the piston is at the top. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of WTWH Media. Pressure gauge kits with different scale divisions: 63mm with glycerol bath back end G1/4 cyl. Mounting a piston accumulator horizontally will cause more rapid wear of the piston seals. 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. 0000005462 00000 n
This also is a good way to tell if an automatic dump valve has opened as it should. When the gauge reaches the current pre-charge of the accumulator, it will then drop immediately to 0 psi. The first indication of this is an increase in the pre-charge pressure when no nitrogen has been added. They can also accommodate for lost pressure if the system's pump fails or there is fluid loss in the system.
These charging kits an indispensable instrument for checking, adjusting or filling nitrogen (N2) into most of the hydraulic accumulators available on the market. or excessive wear of
Oil can be removed from the top of the accumulator by attaching the charging rig and opening the bleeder valve with the system pressurized, removing all nitrogen and oil. Warning:To avoid injury use a Pressure Regulator on your nitrogen bottle when charging an accumulator with a charging kit. Please contact usfor a quote on charging equipment or to set up a service appointment. AI-CG10-10KT-SS is rated to 10000 PSI maximum working pressure. 0000107604 00000 n
Use dry nitrogen gas (N2) only. Hydraulic accumulators should be carefully inspected visually at least once per year, more often in environments unfriendly to steel. 
Other pressures and metric gauge markings are also available. 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. 0000050314 00000 n
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. 0000007881 00000 n

With the nitrogen bottle connected, crack the valve on the bottle and slowly add nitrogen until the pre-charge reaches the desired level. Look for loose mounting points, worn rubber and any indication of movement during operation. If the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter it. Something went wrong. If the pre-charge is higher than it should be, the bladder in a bladder accumulator will hit the poppet assembly during each cycle, causing either a cut bladder or excessive stress wear of the spring in the poppet. 0000010574 00000 n
In general, it is better to undercharge than overcharge. The pre-charge can be checked without the charging rig by watching the gauge fall when the system is shut down and the dump line is opened.

Leader Hydraulics Limited Please contact us for more information. System pressure drops, stalls may be noted, and the piston can become damaged by repeatedly hitting the bottom of the accumulator. 
It is highly recommended that a N2 gas regulator be used while charging any accumulator. It is highly recommended that a N2 gas regulator be used while charging any accumulator. We are also able to help charge your in-field accumulators through our network of distributors or with our on-site service and repairprogram. Unfortunately, in many instances, the OEM pre-charge pressure is not available, and the minimum acceptable pressure is unknown.
