Maintenance of Sumitomo hydraulic cylinder seals
Daily maintenance and upkeep can effectively solve the sealing problem of hydraulic cylinders, extend the service life of hydraulic cylinders, and improve the work efficiency of construction machinery.
1. Regularly check the wear of the hydraulic cylinder seals, and if severe wear is found, it should be replaced in a timely manner.
2. Clean the hydraulic cylinder seals to prevent impurities such as dust and sand from entering the interior of the seals.
3. Use appropriate hydraulic oil and avoid using expired or non compliant hydraulic oil to avoid damage to the hydraulic cylinder seals.
4. Avoid using hydraulic cylinders under excessive pressure or load to avoid damage to the seals.
5. Regularly check the liquid level and pressure of the hydraulic cylinder to ensure its normal operation and avoid damage to the sealing components due to hydraulic cylinder failures.
6. When the hydraulic cylinder is stopped for a long time, regular maintenance should be carried out, such as applying anti rust oil, to prevent aging or deformation of the sealing components.
