What is Hydraulic accumulator – Types Of Hydraulic Accumulator
What is Hydraulic accumulator – Types Of Hydraulic Accumulator. Introduction to Accumulators : A hydraulic accumulator is a device that stores the potential energy of an incompressible fluid held under pressure by an external source against some dynamic force. This dynamic force can come from different sources.

Guidelines for Understanding and Maintaining Hydraulic Accumulators
A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. Which function it will perform depends upon its pre-charge. If the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter it.
