Hydraulic Accumulator
A hydraulic accumulator is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure by an external source. The external source can be a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage device.
Working Principle
When machine is not working then fluid from the inlet is getting in through pump but not getting out as machine is not working.So it gets stored in an accumulator now as the machine starts working the pressure of fluid from the accumulator plus fluid from pump tries to do the work as a result machine starting effort is reduced.
Advantages
>Stores energy
>Absorbs pulsation
>Acts as shock absorber
>Maintains pressure
>When pump stops working then it acts as support to continue work
