Hydraulic accumulators store energy, enhance the performance of fluid-power systems and provide for emergency backup functions. An accumulator consists of a separation element (bladder, piston or diaphragm) that divides gas and fluid sections.
An accumulator consists of a separation element (bladder, piston or diaphragm) that divides gas and fluid sections. The energy storage capacity is directly affected by the precharge pressure of nitrogen gas inside an accumulator.
Bladder accumulators provide a means of regulating the performance of a hydraulic system. They are suitable for storing energy under pressure, absorbing hydraulic shocks, and dampening pump pulsation and flow fluctuations.
Accumulator failure is generally defined as inability to accept and exhaust a specified amount of fluid when operating over a specific system pressure range. Failure often results from an unwanted loss or gain of precharge pressure. Correct precharge pressure is the most important factor in prolonging accumulator life.
The accumulator is empty, and neither gas nor hydraulic sides are pressurized. The accumulator is precharged. The hydraulic system is pressurized. As system pressure exceeds gas precharge hydraulic pressure fluid flows into the accumulator. System pressure peaks. The accumulator is filled with fluid to its design capacity.
