Gas-Over-Oil · Shock & Pulsation Damping
Nitrogen Shock Accumulator Cylinders
High-frequency shock mitigation and energy storage cylinders for mining mobile crushers, drill rigs, and heavy industrial circuits.
Nitrogen shock accumulator cylinders isolate severe vibrations, hydraulic ripple, and sudden mechanical shocks by utilizing a compressible pre-charged nitrogen gas chamber separated from the oil circuit by a heavy-duty floating piston or bladder.
Gas-Over-Oil · Shock & Pulsation DampingEngineering detail
Custom engineered & quality-tested in-house.
Designed with ultra-smooth micro-honed interior surfaces to maximize seal life under rapid cycling. Equipped with certified high-pressure gas filling valves and burst-disc safety assemblies.
Engineering Highlights
- Instantaneous response time to absorb peak hydraulic pressure spikes
- Low-friction composite piston rings prevent stick-slip during micro-oscillations
- Built-in corrosion-resistant gas valve block for fast pressure verification and re-charging
- Dramatically extends the operating lifespan of downstream pumps, valves, and hoses
