A hydraulic bladder accumulator is the hydraulic equivalent of a spring in that it stores energy and dampens an impulse or force.
Storage of an incompressible, high pressure hydraulic fluid is accomplished through the use of compressed nitrogen gas in an elastomeric bladder enclosed in a high strength steel pressure vessel.
The nitrogen gas is precharged to a percentage of the maximum desired hydraulic pressure, and as the hydraulic fluid is pumped into the accumulator, the gas compresses as pressure is increased. Upon demand from the hydraulic system, the stored hydraulic energy allows for rapid discharge or absorption of pressure impulses.
Reduction of pump capacity requirements which
provide long term energy savings and lower pump
Surge Control & Shock Absorbers:
Pulsation dampening and noise reduction caused by
pumps and “water hammer”.
Eliminate Sudden Pressure Drops:
Maintain constant pressure on a hydraulic system such
as a press line where multiple presses are opened and
closed at different times.
Compensates for pressure variations caused by
temperature changes within a
& Safety Failsafe:
Provides stored fluid power for operation of hydraulic equipment power failure.
