Application classification function of hydraulic accumulator

Hydraulic accumulators serve two purposes.

(1) when moving at a low speed, the flow required by the load is less than the flow of the hydraulic pump. The surplus flow of the hydraulic pump from xiangshan accumulator manufacturer enters the accumulator. When the flow required by the load is larger 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) even if the stop also need to maintain a certain pressure of the case, stop the oil pump, compensate the energy storage device compensation system leakage, so as to maintain the pressure of the system.It can also be used to absorb the pressure pulsation of the hydraulic pump or the hydraulic impact pressure generated by the absorption system. The pressure of the accumulator is compressed gas.

Yinzhou accumulator manufacturers can be divided into gas type, heavy hammer type and spring type.The direct contact between gas and liquid in gas accumulator is called contact type, yinzhou accumulator manufacturer has simple structure, large capacity, easy to mix gas in liquid, often used in hydraulic press

Gas and liquid do not contact isolation type, commonly used bag and diaphragm isolation, bag volume change is large, membrane volume change is small, often used to absorb pressure pulsation

Heavy hammer type capacity, in rolling mill and other systems often used, can supply energy.?The types of compression-level effects of hydraulic energy storage devices are as follows: spring and inflatable.Function of accumulator

Short term substantial supply

The system pressure

The emergency energy

Shock pressure

The functions of pulsating pressure accumulator are mainly divided into four categories: energy storage, hydraulic shock absorption, pulsating elimination and energy recovery.

One: store energy.This function can be subdivided into :(1) auxiliary power source to reduce the machine capacity;(2) compensation for leakage;(3) thermal expansion coefficient compensation;(4) set it as an emergency power source;(5) constitute a constant pressure oil source.

2: suction valve suddenly turn, execution unit movement suddenly stops, the hydraulic system pressure, system pressure rise rapidly in a short time, cause the damage of instrument, components and sealing device, due to the accumulator should be arranged near the impact point, hydraulic pressure to ensure that the absorption effect of so accumulator are usually installed in before impact source such as control valve and hydraulic cylinder.It absorbs and slows down very well
