What causes the hydraulic cylinder to leak oil?
Normally, there are two types of hydraulic oil cylinder leakage: external oil leakage and internal oil leakage. I. External leakage 1. The seal between the extension end of the piston rod and the piston rod is damaged, mostly due to the aging of the piston rod and the formation of burrs. 2. The seal between the protruding end of the piston rod and the cylinder liner is damaged. This is mostly due to the long-term use of the seal and the aging of the seal ring. There are also many damages caused by the upper cover extruding the seal kit. 3. The crack of the hydraulic cylinder inlet and outlet pipe joints will also cause leakage of the hydraulic cylinder. 4. Oil leakage caused by defects on the cylinder block or cylinder head. 5. The piston rod is strained and damaged, with pits, etc. 6. The deterioration of the lubricating oil increases the temperature of the hydraulic cylinder and promotes the aging of the sealing ring. 7. The oil leakage is usually formed by using beyond the press...
