The average pressure in the accumulator is 1.5 bar. Depending on the volume of the tank, it can be reduced or increased. It should be remembered that an excessive decrease in the indicator leads to wear of the membrane, and an increase leads to an additional load on the pipes and line assemblies.

Accumulator. An accumulator is a vessel which is partly filled with liquid and partly with gas (often air); its internal pressure is generally higher than atmospheric pressure. Accumulators store fluids to be handled under increased pressure (e. g. in pressure booster systems) in order to attenuate surge pressures and serve as energy storage

an accumulator full of fluid, the pressure on the accumulator side initially diminishes slowly according to laws regarding the physical properties of gas, but then suddenly drops off when the relative pre-loading gas value is reached. Such a phenomenon can be noticed with the aid of a manometer measuring accumulator fluid pressure directly.
