A hydro-pneumatic accumulator charged to 3,000 psi is essentially a tube of nitrogen stuffed with over 200 times the volume of air compared to its surrounding atmosphere. That 3,000 psi wants badly to become 14.7 psi again, and when given the opportunity, will disperse its energy as rapidly as possible to equalize.

If a bladder accumulator is charged too fast, high-pressure nitrogen, expanding rapidly becomes cold and chills the bladder. The chilled, brittle rubber, expanding rapidly could potentially rupture. The bladder could also be forced under the poppet and torn. Contact Us Freephone 0800 068 4134 Phone +44 (0)1159 003550 Email [email protected]

Accumulator Charging Valves. The function of the Accumulator Charging Valve is to control the charging of the accumulator within a preset switching range. There are integrations of a pilot stage with defined hysteresis, a main piston, and a check valve into the circuit. Therefore, the charge of the accumulator happens at port A from pump port P

Pre-Charge Procedure. 1. Install the hose end of the gauging/charging assembly onto the nitrogen gas bottle. 2. Verify the gas chuck is backed all the way out on the gauging assembly. 3. Make sure the bleed valve is closed. 4. Once steps #2 and #3 are verified, begin installing the gas chuck onto the gas valve.

This assembly is used to provide Nitrogen precharge to 3000 psi and lower accumulators. The accumulator will need to have a Schrader style gas valve, or you will need an additional adapter to assist. Do not use on accumulators with a pressure higher than 3000 PSI. It is highly recommended that a N2 gas regulator be used while charging any

The hydraulic accumulator, Figure 2.31, is an energy storage device in which one end is closed and another is connected to the hydraulic pipes. The hydraulic accumulator is divided into three parts: compressed gas (air chamber), piston, and hydraulic fluid (oil chamber). Figure 2.31. Hydraulic accumulator structure.

Calculate accumulator. Many different factors impact on calculations for accumulators. The calculations below should only be used to obtain estimates. The assumptions used in the calculations are rapid (adiabatic) charging and discharging, i.e. the time is less than three minutes. Polytropic exponent = 1,5. Separate decimals with a decimal point.

Note: Make sure that the accumulator has a proper nitrogen gas charge before attempting to test the check valve. An improperly charged accumulator may give indications of a problem with the check valve. Stop the engine. Release the pressure from the pilot hydraulic system. Refer to Testing and Adjusting, “Hydraulic System Pressure – Release”.

The accumulator will respond more rapidly to pressure spikes if the compression process has already begun. For this reason, it usually is recommended that shock accumulators be pre-charged to nearly 100 psi below the maximum load pressure of the actuator it protects. It is not advisable to use a piston accumulator to absorb shock.

The "pressure drop point" is the pre-charge pressure. Piece of cake! Often it is possible to perform this check without removing the accumulator from its place since it can be pressurized by the system pressure, and then the manual safety discharge valve (if equipped with one, of course) can be conveniently used for the "slow venting".
