Overview of the functions and uses of bladder type accumulators(一)

Bag type accumulator is an indispensable and important component in hydraulic components, playing an important role in hydraulic components. To understand the functions and uses of bag type accumulator, the following is an overview from Zhongya High tech Hydraulic – Bag type Accumulator Manufacturer:

There are two uses for bag type accumulators hydraulic accumulator diaphragm.

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

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

Bag type accumulators can also be used to absorb the pressure pulsation of hydraulic pumps or the hydraulic impact pressure generated in the system. The pressure in an accumulator can be generated by compressed gas, a heavy hammer, or a spring, and the accumulator can be divided into gas type, heavy hammer type, and spring type accordingly. The direct contact between gas and liquid in gas accumulators is called contact type, which has a simple structure and large capacity, but gas is easily mixed into the liquid, and is commonly used in hydraulic presses. Gas that does not come into contact with liquid is called an isolation type, which is commonly isolated by a skin bag and a diaphragm. The volume change of the skin bag is large, while the volume change of the diaphragm is small, and it is commonly used to absorb pressure pulsation. The heavy hammer type has a large capacity and is commonly used in systems such as rolling mills for energy storage bladder accumulator ehv .
