Guidelines for Understanding and Maintaining Hydraulic Accumulator…
Release any pressure at the accumulator inlet. Most accumulators have a dump valve that can be opened to drain oil to the tank. Screw the charging rig onto the accumulator''s Schrader valve and turn the gas chuck handle clockwise to depress the pin. The current pre-charge can then be read on the charging rig.
Recommendations for accumulator selection | Power & Motion
Pressure — The accumulator''s maximum allowable working pressure should meet or exceed the system''s maximum pressure. System spikes must be identified and accounted for. In general, accumulators are available in 150 psi to 10,000-psi models, with 3000 psi and 6000 psi among the most popular. Never use the accumulator''s proof …
