Hydraulic Accumulator
Key Features
-
Pressure Energy Storage
Stores pressurized hydraulic energy using nitrogen gas precharge and releases the stored energy when additional hydraulic power is required.
-
Pressure Stabilization
Absorbs instantaneous pressure fluctuations and pulsations caused by pump operation and valve switching, helping maintain stable system pressure.
-
Emergency Power Reserve
Provides stored hydraulic energy during pump failure or power interruption, while helping compensate for system leakage.
-
Pulsation Damping
Helps reduce pressure pulsations in high-pressure hydraulic and emulsion systems for smoother system operation.
-
High-Strength Construction
Manufactured with a seamless high-strength steel shell and internal and external anti-corrosion treatment for demanding operating environments.
-
Mining Application Ready
Supplied with a product conformity certificate and factory pressure test report for applicable mining hydraulic systems.

How It Works
The hydraulic accumulator stores hydraulic energy through a nitrogen gas precharge.
During normal operation, pressurized hydraulic fluid enters the accumulator and compresses the gas, storing energy inside the vessel.
When the hydraulic system requires additional flow or pressure support, the stored energy is released back into the hydraulic circuit.
The accumulator can also absorb excess energy during sudden pressure increases, helping reduce pressure spikes and pulsations caused by pumps and valves.
This enables the accumulator to perform several functions within one hydraulic system:
Energy Storage → Pressure Stabilization → Pulsation Damping → Leakage Compensation → Emergency Power Reserve
