• Accumulator Selection
  • a. Working Pressure: P1 and P2
    P1 means gas pressure at the minimum hydraulic pressure, while P2 means gas pressure at the maximum hydraulic pressure. For safety considerations, P2 must be lower than or equal to the maximum working pressure of the accumulator.
    b. Work Fluid Quantity: ΔV
    This parameter indicates the fluid quantity that could be stored or released, and it is needed to correctly determine the accumulator size.
    c. Application Field
    It is very necessary to make sure what kind of state the gas is in during operation, isothermal or adiabatic. If the compression or expansion process is conducted slowly, say 3 minutes or more, the gas will keep its temperature at a relatively constant value, and this is isothermal state.
