These several reasons may cause the leakage of rubber dust cover seal
During the rubber dust cover seal process, there are certain reasons that may cause the rubber dust cover seal to leak. Below we have compiled the relevant content of the analysis of several reasons that may cause the rubber dust cover seal to leak.
First of all, the leakage of the rubber dust cover seal may be due to installation problems. The seals are installed in the wrong direction to cause the leakage. Mixing in during installation or foreign matter or dust in the pipeline entering the sealed cavity may cause leakage.
Damage to the seal caused by improper assembly may also cause leakage. Scratches on the surface of the seal rod may also cause leakage. The piston rod is not centered and eccentric load may cause leakage. In addition, the second major cause of seal leakage is seal structure design and assembly problems, including improper selection of cavity support materials, improper wear of the cavity and piston rod, cylinder barrel, and improper spiral lead angle at the end of the piston.
Another reason is that the rubber dust cover seal leak is due to the selection of the seal. Generally, the pressure is too high and the hardness of the seal is too small, and the metal groove may be extruded. The sealing material is compatible with the medium, and the seal is softened or Dissolve.
The seal is used when the temperature is too high, the seal material is carbonized. Low temperature will easily cause the sealing material to harden, shrink and cause leakage, and the use of line speed is too high, resulting in heat generation, dry grinding, and carbonization of the sealing element to form leakage.
