Hydraulic Cylinder Maintenance Tips
To ensure optimal performance and extend the lifespan of your hydraulic cylinders, consider the following maintenance guidelines:
1.Check Hydraulic Oil Quality
Always verify that the hydraulic oil in the system meets the required specifications. The oil should be clean and free from contamination. If there are signs of impurities, filter or replace the oil promptly to avoid damage to internal components.
2.Monitor Operating Hours and Replace Seals as Needed
Keep track of your cylinder's working hours. Once the service time exceeds 6,000 hours, it is advisable to inspect and replace the seals to maintain sealing performance and prevent leaks.
3.Inspect Installation and Alignment on Filter-Related Cylinders
For cylinders used in filter systems, clean any sludge buildup from the filter plates regularly. Also, observe the piston rod's motion-if it appears misaligned or tilted during extension and retraction, adjustment is necessary to prevent uneven wear or mechanical failure.
4.Ensure Proper System Design for High-Pressure Cylinders
To protect high-pressure hydraulic cylinders, it's recommended to include both air-bleed valves and pressure relief mechanisms during system design. These additions help prevent pressure build-up and improve overall safety and reliability.
