Accumulator: Description and Operation
Accumulator Assembly
Accumulator And Switches
The accumulator has a nitrogen charged chamber separated from the pressurized hydraulic oil by a diaphragm. The pressurized nitrogen stores system
pressure and maintains boost pressure when the pump is inoperative or if a failure occurs. A non-return valve prevents return flow and maintains
pressure on the accumulator side of the system. Two pressure switches are mounted on the accumulator base.
Charge switch operating pressures should be:
Open (no system charging) ...................................................................................................................................................................... 1450 psi (100 bar)
Closed (system charging) ......................................................................................................................................................................... 1204 psi (83 bar)
Low pressure warning switch pressures should be:
Open (VCM warning on; UP disabled) ....................................................................................................................................................... 783 psi (54 bar)
Closed (VCM warning off; UP enabled) ................................................................................................................................................... 1000 psi (69 bar)
