Why does new hydraulic seal leak?
Why does new hydraulic seal leak?
1. When installing the hydraulic seal, if you do not pay attention to cleaning the installation site, resulting in not being a tight hydraulic seal. The repairmen will remove the burrs on the chamfer of the cylinder seal before installing of the hydraulic seal. This minor detail will greatly reduce the probability of cylinder seal damage.
2. When replacing the hydraulic seal, if you do not check the damage of the cylinder before replace new hydraulic seal. It is recommended that before replacing the new cylinder seal, first check whether the cylinder has scratches, scratches, etc. If there is, then it must be handled as appropriate, otherwise the piston rod will reciprocate once, even if it is new. The hydraulic seal will also increase abrasion, and the hydraulic seal will naturally be damaged for a long time.
3.Excessive pressure in the hydraulic system can also cause deformation of the hydraulic seal. Simply speaking, the system pressure has exceeded the hydraulic seal limitation. The hydraulic seal or cylinder seal is deformed under high pressure and even hit by high pressure hydraulic oil into several sections.
4. There are contaminants, impurities, external dust, fine particles, etc. in the hydraulic oil, which can easily cause the hydraulic seal of the fitting to wear out, and must be replaced until it is completely scrapped.
5. The high temperature of the hydraulic oil does not need to be described too much about this issue. As there are countless examples of hydraulic seals that must be replaced every year because of the high oil temperature and accelerated oil seal or hydraulic seal or cylinder seal aging. If the root cause of the oil seal or hydraulic seal or cylinder seal damage is high, the machine owner should take time to repair it!
6. Long-term purchase and installation of aftermarket oil seal or hydraulic seal or cylinder seal, or the quality of oil seals or hydraulic seal or cylinder seal cannot be guaranteed. In addition to the short life of the seals, the sealing effect is certainly not up to the requirements, and oil spills and the like are no exception.
