Product Description

       The accumulator is an energy storage device in the hydraulic pneumatic system. It converts the energy in the system into compressed energy or potential energy at the appropriate time and stores it. When the system needs it, it also converts the compressed energy or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the instantaneous pressure of the system increases, it can absorb this part of energy to ensure the normal pressure of the whole system.

Working principle of accumulator:

1)Use the compressibility of gas and the incompressibility of liquid to store and release liquid energy.
2)The skin sac acts as a diaphragm to separate gas and liquid.
3)The accumulator (leather bag) is filled with nitrogen.
4)When the liquid enters the accumulator, the gas is compressed, and the volume of the compressed gas is stored.
5)The stored fluid has hydraulic energy and can be released when necessary.

Application

1)When the flow required by the load at low speed is less than the flow of the hydraulic pump, the excess flow of the hydraulic pump is stored in the accumulator. When the flow required by the load is greater than the flow of the hydraulic pump, the liquid is discharged from the accumulator to compensate for the insufficient flow of the hydraulic pump.

2)When the machine is stopped but still needs to maintain a certain pressure, the hydraulic pump can be stopped and the accumulator can compensate the leakage of the system to maintain the pressure of the system.

The accumulator can also be used to absorb the pressure pulsation of the hydraulic pump or the hydraulic shock pressure generated in the system. The pressure in the accumulator can be generated by compressed gas, heavy hammer or spring, and the accumulator can be divided into gas type, heavy hammer type and spring type. The direct contact between gas and liquid in the gas accumulator is called contact type. Its structure is simple and its capacity is large, but the liquid is easy to be mixed with gas. It is often used in hydraulic compressors. The gas that does not contact with the liquid is called the isolation type. It is often isolated by the skin bag and the diaphragm. The volume of the skin bag changes greatly while the volume of the diaphragm changes slightly. It is often used to absorb the pressure pulsation. The heavy hammer type has large capacity and is often used in rolling mill and other systems for energy storage

 

Reserve Energy Storage

 

The accumulator can assist the pump body by adjusting the release of internal hydraulic oil. After the accumulator is equipped,
the specification requirements of the pump can be appropriately reduced to achieve scientific energy conservation and efficiency

Reduce Pulsation Impact

In the fluid circuit, due to the flow of liquid, it will more or less produce pulsating impact on the equipment, and even produce
stronger impact when various valves are closed and the circuit fluid changes sharply. After installing the accumulator, it can be
used as a buffer to effectively reduce pulsation and impact

Maintain Stability

When the external pressure or weight has an impact on the equipment system, the accumulator can well bear the change of external
weight by adjusting its internal gas and liquid balance, so as to avoid severe shaking and fluctuation of the equipment and
maintain the balance and stability of the equipment.

Pressure Volume Compensation

In the pressure circuit, in case of internal leakage or changes in external factors such as pressure and temperature, which
changes the volume of liquid oil in the system and affects the stability of internal pressure of the system, the accumulator can
be used as timely compensation to maintain the stability of the hydraulic system
