The accumulator can assist the pump body to work by adju- sting the release of internal hydraulic oil. After the accumul- ator is equipped, the specification requirements for the pump can be appropriately reduced to achieve scientific energy conservation and efficiency increase.

In the fluid circuit, due to the flow of liquid, more or less imp- ulse shock will be generated on the equipment, even when various valves are closed and the loop fluid changes sharply, more intense impact will be generated. After the installation of the accumulator, it can be used as a buffer to effectively reduce pulsation and impact.

When the external pressure or weight has an impact on the equipment system, the accumulator can well withstand the changes of external weight by adjusting its own internal gas and liquid balance, avoid the violent shaking and fluctuation of equipment and maintain the balance stability of equipment.

In the pressure circuit, when encountering internal leakage, or changes in external factors such as pressure and temperature, which change the volume of liquid oil in the system and affect the stability of the internal pressure of the system, the accum- ulator can be used as a timely compensation to maintain the stability of the hydraulic system.
