Bladder Accumulators – Standard

BladderAccumulator_Standard

Fluids are practically incompressible and cannot, therefore, store pressure energy.

The compressibility of a gas is utilised in hydraulic accumulators for storing fluids. HYDAC bladder accumulators are based on this principle, using nitrogen as the compressible medium. A bladder accumulator consists of a fluid section and a gas section with the bladder acting as the gas-proof screen. The fluid around the bladder is connected to the hydraulic circuit so that the bladder accumulator draws in the fluid when the pressure increases and the gas are compressed. When the pressure drops, the compressed gas expands and forces the stored fluid into the circuit.

HYDAC bladder accumulators can be used in a wide variety of applications, some of which are listed below:

  • Energy storage
  • Emergency operation
  • Force equilibrium
  • Leakage compensation
  • Volume compensation
  • Shock absorption
  • Vehicle suspension
  • Pulsation damping
  • See catalogue section: Hydraulic Dampers No. 3.701

Specifications:

  • V = 0.5 … 200 l
  • p = 330 … 1,000 bar
