12/21 · Accumulators are ASME-coded pressure vessels for the storage of high-pressure fluid. These accumulators as a part of the BOP control unit are available in a variety of sizes, types, capacities, and pressure ratings. The two (2) basic types are bladder and float which are available in cylindrical or ball styles.

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

Hydraulic Accumulators operate on the principles of Boyle's Law of Gases! The basic relationship between the pressure and the volume of gas is expressed by the equation: P1V1n= P2V2n, where P1 and P2 are the initial and final gas pressures and V1 and V2 are the corresponding gas volumes.

The maintenance interval of pre-charge pressure depends on several factors that should be considered. Loss of pre-charge gas happens with all three common types of accumulators — piston, bladder, and diaphragm. The loss due to permeation of gas is negligible in a piston type, but it is an inherent problem with bladder and diaphragm types.

The accumulator should be set a few psi below cut-IN pressure ie: the lower of the two pressures over which the pump works (typically 30psi to 20psi) so anything around 15psi should be fine (~1 bar). (This is specifically for a water pump accumulator. A heating system pressure accumulator is set differently.) Chris

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.
