Accumulators

  • Accumulators
  • Pressure accumulators, a mechanism that uses the compressibility of nitrogen gas. They are used for capacity correction and pulsation absorption in fluidic circuits.

    Accumulators are an essential function to enable the potential energy of fluids to act effectively, and maintain high-accuracy operations of oil, water and other fluidic circuits in a safe and economic manner. The principle of operation is based on the compressibility of nitrogen gas. The container is designed to accumulate fluid pressure, and release a large amount of pressurized fluid instantaneously, or absorb pulsation and impact pressure.
    According to the method of separating the nitrogen gas from the fluid, accumulators are classified into two types: the bladder type and piston type. The bladder type is the more popular.
