ACCUMULATORS

Hydra Dyne Tech manufactures a wide range of piston accumulators with customizable options for both industrial applications and mobile hydraulic requirements. A piston accumulator contains a compressible non-explosive gas – nitrogen, on one side of the piston (gas section) and the other side (fluid section) is connected to hydraulic circuit to allow the hydraulic fluid to flow in and out at high speeds.

The nitrogen inside the accumulator is pre-charged to the desired pressure as per the demands of the application. When the hydraulic pressure in the system spikes, hydraulic fluid flows into the accumulator and pushes the piston by compressing the nitrogen gas. When there is a drop in the system pressure, the stored fluid is forced back into the circuit as the compressed gas expands. This phenomenon allows for a functional & efficient hydraulic system with dampened pulsations, controlled flow fluctuations, shock absorption and restoration of hydraulic energy in case of any loss.

The major advantage of having a piston type accumulator over the bladder type is, that the piston accumulator can be fully discharged and it also allows for a gradual loss of pre-charge pressure in case of any failure.
