1, as an auxiliary power source, to provide a certain amount of pressure oil to the system.

 

2. As an emergency power source, it can supply a certain flow of pressure oil to the hydraulic system in a short time to ensure the safe operation of the hydraulic device. That is to say, when the motor hydraulic pump group fails or a power failure occurs, the accumulator can continue to provide a certain flow of pressure oil to the hydraulic device, so that the executive components of the system can continue to complete the specified action in accordance with the process (sequence) requirements.
 

 

3, as the hydraulic system hydraulic oil leakage loss compensation device, so as to better ensure the stability of the system working pressure.

 

4. Eliminate the hydraulic shock caused by the rapid change of oil flow speed or direction in the hydraulic system.

 

5. Absorb pressure and flow pulsation of hydraulic system.
