The maintenance and maintenance methods of hydraulic cylinders include the following points:
Regularly replace hydraulic oil and clean the system filter to ensure cleanliness and prolong service life.
Every time it is used, carry out a test run of 5 strokes of full expansion and full contraction, and then run it with load to exhaust the air in the system, preheat each system, and effectively avoid the existence of air or water in the system. Cause gas explosion (or scorch) phenomenon, thus damage the seal, cause the oil cylinder internal leakage and other failures.
Control the system temperature well. Too high oil temperature will reduce the service life of the seals. Long-term high oil temperature will cause permanent deformation or even complete failure of the seals.
Protect the outer surface of the piston rod to prevent damage to the seal from bumps and scratches. Frequently clean the dirt on the seal dust ring of the oil cylinder and the exposed piston rod to prevent the dirt that is not easy to clean on the surface of the piston rod from entering Damage to the piston, cylinder or seals inside the cylinder.
Frequently check the connecting parts such as threads and bolts, and fasten them immediately if they are found to be loose.
Regularly lubricate the joints to prevent corrosion or abnormal wear in the oil-free state.
