Hydraulic accumulator

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy.The external source can be an engine, a spring, a raised weight, or a compressed gas. [note 1] An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to

The design and physical construction of bladder and diaphragm accumulators limits their maximum operating pressure ratios. Exceeding those limits can damage the bladder or diaphragm. A piston accumulator accommodates higher pressure ratios because it does not have an elastomer membrane subject to damage. Accumulator Safety

Minimum operating pressure is 1,200 psi (200 psi over pre charge pressure) Usable fluid per gallon is 5 gallon. Safety factor require is 50 %. This safety factor may be different depending on each company’s requirement.

What psi should a gas accumulator be precharged?

Gas Precharge usually 100 psi below minimum pressure for Piston Accumulators*. Gas precharge is 90% of minimum pressure for Bladder Accumulators. *90% where minimum system pressure is less than 1000 psi. Existing accumulator output used in an auxiliary power source application.

Can accumulator bottle pressure exceed rated working pressure?

When it comes to operating an accumulator bottle, the pressure should never exceed its rated working pressure. During the initial closing unit installation, each accumulator bottle’s pre-charge pressure should be measured; this should occur on each well before then being adjusted, wherever required.
