Product Description

Professional Production Of High Quality Hydraulic Accumulator

    Hydraulic accumulators are energy storage devices. Analogous to rechargeable batteries in electrical systems, they store and discharge energy in the form of pressurized fluid and are often used to improve hydraulic-system efficiency. In these hydropneumatic units, hydraulic fluids only compress slightly under pressure. In contrast, gases can be compressed into smaller volumes under high pressures, and engineers take advantage of this property in accumulator design and application. In essence, potential energy is stored in the compressed gas and released on demand to force oil from the accumulator and into a circuit.

How does a hydraulic accumulator work?

    To use the device, the gas volume is first precharged-generally to around 80 to 90% of the minimum system working pressure. This expands the gas volume to fill most of the accumulator with only a small amount of oil remaining inside. 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 balanced. When a downstream action such as actuator movement creates system demand, hydraulic system pressure falls and the accumulator releases the stored, pressurized fluid to the circuit. When movement stops, the charging cycle begins again.


    A diaphragm accumulator can handle higher compression ratios of up to 8 to 10:1 because the rubber barrier does not distort to the same degree as a bladder. They also enjoy wider mounting flexibility, are insensitive to contamination and quickly respond to changes in pressures, making them suited for shock applications. Accumulators store energy that can be used to supplement pump flow, improve system response or serve as a back-up during power failure. They can also compensate for leakage or thermal expansion, and reduce vibration, pulsations and shock.
