Hydraulic accumulators function by compressing a gas (typically nitrogen) against a liquid (hydraulic fluid) using a bladder or piston. When the system demands hydraulic energy, the stored gas expands, forcing the liquid out. This helps maintain system pressure, reduce pump load, and provide a buffer against sudden pressure surges.
Benefits of using hydraulic accumulators:
- Pressure maintenance: Maintains system pressure, preventing pressure drops and ensuring consistent performance.
- Shock absorption: Absorbs sudden pressure surges, protecting system components and reducing wear and tear.
- Pump unloading: Reduces the load on pumps by storing energy during low-demand periods.
- Emergency power supply: Can provide a backup power source in case of pump failure.
- Smoother operation: Improves system smoothness and reduces noise.
