Turn off your system and release all hydraulic or fluid pressure. 2. Remove gas protective cap and valve cap from the accumulator. 3.

Accumulators increase efficiency and provide smooth operation

Two designs of accumulators are widely used in hydraulic systems — piston and bladder accumulators, Figure 1. Piston accumulators include weight-loaded piston type, spring type, and hydropneumatic piston type. The weight-loaded type was the first used, but is very heavy for its capacity and much larger than modern piston and bladder types.

Common Hydraulic Accumulator Problems and How to

Holding Time Test: Check the holding time of the accumulator by closing off the hydraulic supply and monitoring the pressure drop over a certain period. A rapid pressure drop suggests gas leakage. Visual Inspection: Examine the accumulator bladder or piston for any damage or deterioration that could be causing gas leakage.
