The hydraulic accumulator stores some of the fluid under pressure and sends it back into the circuit if necessary. The pressure accumulator can do different things in different circuits.

To store oil, there may be a great need for oil in the circuit for a short time, here the pump is not designed to produce this maximum current for a short time. The pump discharge is lower and fills the accumulator during a working cycle when the pump discharge is higher than the circuit needs.

Now, if a part of the work cycle requires the maximum flow of oil in the circuit. Therefore, the use of an accumulator prevents the use of a large pump and a large electric motor to provide maximum current in a short period of time.

Uses of accumulator in the system:

As an emergency unit, whenever the pump or electric motor of the pump is driven due to non-virtual pressure, the accumulator shuts them down before it is damaged. Compensates for leaks, compensates for any losses or oil leaks, thereby keeping the pressure constant for a long time. Creating volumetric equilibrium, at different degrees of temperature, keeps the volume constant. To reduce the maximum pressure when changing mode or changing the position of the circuit. To reduce the impact, reduce the maximum pressure on the pump. Brake power supply.

Types of accumulators:

•  Weight accumulator
• Spring accumulator
• Piston accumulator
• Balloon accumulator
• Diaphragm accumulator
