introduction:A device for storing liquid pressure energy in a hydraulic transmission system。Accumulators are used in two ways。①When moving at low speed, the flow required by the load is less than the flow of the hydraulic pump,The excess flow of the hydraulic pump is stored in the accumulator,When the load required flow is greater than the hydraulic pump flow,The fluid is released from the accumulator,To supplement the hydraulic pump flow insufficiency。②When the machine is shut down but still needs to maintain a certain pressure,The hydraulic pump can be stopped and the accumulator compensates for the leakage of the system,To keep the pressure on the system。Accumulators can also be used to absorb pressure pulsations from hydraulic pumps or to absorb hydraulic shock pressures generated in the system。The pressure in the accumulator can be compressed gas、It is produced by a hammer or spring
