Hydraulic Accumulators
Hydraulic accumulators are devices in which potential energy is stored in the form of a compressed gas to be used to exert a force against a relatively incompressible fluid. They are used in fluid power systems for pressure maintenance/energy recapture, hydraulic axle suspension, and dampening of vibra-tions, pulsations and shocks. They shorten cycle times, increase operating life, and increase efficiency.
In modern accumulators the hydraulic fluid is separated from the gas by a piston, a diaphragm, or a rubber bladder. Today’s machinery with hydraulic drives would be unthinkable without these hydraulic accumulators—they support the oil-hydraulics within an exceptionally wide spectrum of applications. And, it is particularly important to ensure that the correct configuration of the hydraulic accumulator is specified according to the particular design requirements.
Our accumulators ;meet the requirements of a wide range of specific applications. These accumulators demonstrate outstanding characteristics for every area of application, no matter what the pressure.
