Hydraulic Accumulators
Available46 products. Hydraulic accumulators store pressurized hydraulic fluid and release it as needed to maintain steady pump flow and pressure, dampen vibrations and shocks, and compensate for leaks or thermal expansion in the system. They can also accommodate for lost pressure if the system''s pump fails or there is fluid loss in the system.
Read MoreSizing Hydraulic Accumulators for Various Applications
Hydraulic Accumulators operate on the principles of Boyle''s Law of Gases! The basic relationship between the pressure and the volume of gas is expressed by the equation: P1V1n= P2V2n, where P1 and P2 are the initial and final gas pressures and V1 and V2 are the corresponding gas volumes. The next consideration in sizing accumulators is to ...

A hydraulic accumulator is a pressure vessel that performs many tasks in a hydraulic system. They are used to maintain pressure, store and recapture energy, reduce pressure peaks, power chassis suspensions, and dampen shock, vibration and pulsations. Under gas pressure, accumulators store a volume of fluid that can be re-fed …

Read MoreHydraulic accumulators: how do they work?
In operation, the hydraulic pump raises system pressure and forces fluid to enter the accumulator. (Valves control oil flow in and out.) The piston or bladder moves and compresses the gas volume because fluid pressure exceeds the precharge pressure. This is the source of stored energy. Movement stops when system and gas pressures are …

Clamping. Holding pressure, leakage compensation, and power savings are obtained by using the accumulator in this vise circuit. While the vise jaws are in the clamp position, pressure is held by the accumulator, and pump output is unloaded at low pressure. The accumulator compensates for any leakage past the piston seals in the …

The spherical-type accumulator is constructed in two halves that are fastened and threaded, or welded, together. Two threaded openings exist. The top port accepts fittings to connect to the pressurized hydraulic system to the accumulator. The bottom port is fitted with a gas servicing valve, such as a Schrader valve.
Read MoreAccumulators: The unsung heroes of hydraulic motion control
The peak flows will occur between the accumulator and the valve, so it is best to keep this distance short. Even the most capable motion controller may not be able to compensate for a poorly designed hydraulic circuit, and the selection and location of accumulators is key to helping the motion controller do its work precisely. Conclusions
