How A DIAPHRAGM ACCUMULATOR WORKS:
Over the gas plug screw the gas area is filled with nitrogen,the diaphragm sets itself on the wall of the lower half shell and the in-attached plate locks the oil inlet port.
if hydraulic fluid is now promoted to the accumulator,then the gas in the gas area is compressed.The gas volume becomes smaller under simultaneous increase of pressure and stores the hydraulic fluid.
Turned aroun the accumulator empties itself,as soon as the presure on the liquid side sinks more deeply than the gas presure.
The deformation of the diaphragm is well-known.Those practically inertia and smooth deformation results in an effciency of nearly 100%.
ABOUT THE DIAPHRAGM
The diaphragm guarantees a clean separation between gas and liquid.
Those practically inertia and smooth deformation of the diaphragm results in an efficiency of nearly 100%
The plate trained in the diaphragm prevents their damage in the case of emptying and/or in the case of only gas-laterally filled accumulator.
A The diaphragm is in "Precharge presure position",i.e.it is filled with nitrogen.The buttoned-in pltae locks the oil opening and prevents the destruction of the diaphragm.
B Position with minimum operating pressure.Between diaphragm and oil opening a small liquid quantity must remain,so that the diaphragm/the buttoned-in plated does not close the oil opening with each emptying.P0 must therefore ever be lower than P1.
C Position with maximum operating pressure,The variation in volume △V between the position with minimum and maximum operation presure corresponds the storage fluid quantity
Working principle:
The compressibility of the gas and the non-compressibility of the liquid are used for liquid energy storage and release.
A skin capsule acts as a diaphragm to separate the gas from the liquid.
The accumulator is filled with nitrogen gas (inside the skin capsule).
When the liquid enters the accumulator, the gas is compressed and the volume amount of the compressed gas is saved.
The stored liquid has hydraulic energy and is released when needed.

1. As an auxiliary power source
This is the most common use of the accumulator for short periods of time when the system requires a large amount of pressure oil. For example, in the intermittent action of the pressure system, when the system does not need a large amount of oil, the accumulator will be the hydraulic pump output pressure oil stored, when needed, and then quickly released to achieve the action cycle of the system. In this way, the system can use small flow specifications of the liquid noisy such as pressure pump, both to reduce power loss, but also to reduce the temperature rise of the system.
2. Maintain the system pressure
When the executive element stops moving for a long time, and the need to maintain pressure, in order to reduce energy consumption, so that the pump unload, you can use the accumulator storage of hydraulic oil to compensate for leakage losses in the oil circuit, maintain system pressure.
3. Buffer and absorb pressure pulsation
When the valve is suddenly closed or reversed, the shock pressure generated in the system can be absorbed by the accumulator installed near the source of shock and pulsation source by the god of regret, so that the peak of hydraulic shock is reduced.
4. Emergency power source
When the hydraulic pump failure interrupts the oil supply, the accumulator can provide a certain amount of oil Bi touch loss as an emergency power source, so that the executive components can continue to complete the necessary action.
