Key Daily Maintenance Steps for Piston Accumulator Maintenance

For the daily maintenance of piston type accumulators, the following are some key steps aimed at ensuring their long-term stable operation and reliability:
1、 Appearance inspection and cleaning
Shell inspection:
Regularly inspect the accumulator housing for cracks, deformation, or corrosion. These issues may affect the sealing and structural integrity of the accumulator.
Ensure that the surface of the housing is free of dust and oil stains, and keep it clean. This helps to reduce malfunctions caused by pollution.
Inspection of connecting components:
Check if all pipes, flanges, and connectors are tight and leak free. Loose or leaking connecting components may cause a decrease in pressure and energy loss.
Use appropriate tools and methods for tightening to ensure the reliability of connecting components.
2、 Pressure and Gas Management
Gas pressure monitoring:
Regularly monitor the gas pressure inside the accumulator using a pressure gauge. This helps ensure that the accumulator operates at the correct pressure.
If abnormal pressure (high or low) is found, the cause should be promptly identified and dealt with. Excessive pressure may cause equipment damage, while insufficient pressure can affect energy storage efficiency.
3、 Sealing performance inspection
Seal inspection:
Regularly check whether the sealing components of the accumulator (such as O-rings and gaskets) are intact. These seals are crucial for preventing gas leakage.
Seals that are found to be aged, hardened, or damaged should be replaced in a timely manner. This helps to ensure the sealing performance of the accumulator.
4、 Oil management (if applicable)
For piston type accumulators connected to hydraulic systems, oil management is also required:
Liquid level inspection:
Regularly check whether the hydraulic oil level is within the normal range. A low liquid level may cause pump suction and system failure.
5、 Regular maintenance and upkeep
Regular cleaning:
Regularly clean the internal and external deposits and oil stains of the accumulator. This helps to reduce malfunctions and wear caused by pollution.
Tightening bolts:
Regularly inspect and tighten all fastening bolts on the accumulator. Loose bolts may cause components to loosen and leak.
In summary, by performing the key daily maintenance steps mentioned above, the long-term stable operation and reliability of the piston accumulator can be ensured. These steps cover aspects such as appearance inspection, pressure and gas management, sealing performance inspection, oil management (if applicable), regular maintenance and upkeep, and safe operation and maintenance.
