一、Energy Storage

Accumulator is widely used in the auxiliary energy.It accumulates the oil intermittently outputted by pump while releases fluid more than the pump flux.Therefore,the accumulator helps the pump to be size-miniaturization and energy-saving。

二、Pulsation Absorption（Elimination）

Accumulator absorbs pulsation created by pressure fluid that is released by various pump to protect the pipe from the infection of pressure,noise and vibration。

三、Impact Absorption（Decrease）

In hydraulic circuit,impact in the pipe caused by rapid switching or sudden changing of load brings noise and pipe damage.Accumulator is set to absorb（decrease）the impact。

四、Leakage Compensation

In pressure control circuit and condition of pressure maintaining,accumulator is set to maintain the pressure by compensating the pressure reduction caused by internal and external leakage。

五、Volume Compensation

In closed circuit,internal pressure changes because variety in temperature results in variety of liquid volume。

The accumulator reduces the change of pressure to protect valves.gaskets and pressure gauge from failure。

六、Vibration Absorption

The accumulator absorbs the mechanical vibration for the gas in the accumulator works as spring to reduce the impact and vibration of vehicle。

七、Balance

The accumulator can be used as balance for the gas pressure in accumulator stably balances the weight of product and machine and impact。

八、Fluid separation

The accumulator generally separated the two medium(hydraulic purpose: nitrogen and oil). However, the accumulator canbe also used to transmit pressure between two liquid which can be mixed.
