Hydraulic Accumulator Sizing Equations and Calculator
Accumulators are available which operate at higher pressures. In general, hydraulic accumulators are pre-charged one half of the maximum operating fluid pressure, this is adequate for most applications. For a system operating at 3000 psi, a properly rated accumulator should be pre-charged (nitrogen is typically used) to 1500 psi.
Charged Accumulator
A rule of thumb for the nitrogen pre-charged level is one-half the maximum oil pressure. This is acceptable for most applications. The pre-charge should be replenished when it falls to one-third the maximum hydraulic oil pressure. On a 3000-psi hydraulic system, initial pre-charge should be 1500 psi and replenishment level of 1000 psi.
