EPE Diaphragm Standard Accumulator (AMW-3.5-P-250-C-C2-0-M)

0 out of 5

Accumulator is a device used specifically for storage of liquid under pressure. As liquids, for all practical purposes, are incompressible, this objective is achieved by utilizing the compressibility of gases. A flexible rubber separator i.e., diaphragm is fitted into the accumulator shell. An inert gas – nitrogen – is filled into the diaphragm through a pressure valve to a pressure P . The diaphragm expands, filling the entire volume V of the accumulator shell. When the system (circuit) pressure P is higher than the gas 1 precharge pressure P , the liquid enters the shell and the diaphragm is compressed reducing the gas volume to V .1 Should the liquid pressure rise to P , the volume of gas 2 reduces to V with an attendant rise in pressure, thus 2 balancing the Liquid pressure. A potential energy is now stored in the accumulator to be utilized whenever needed.
