1 check the sealing ring before installation to ensure that the seal is intact.
2 before installation, the lip shall be coated with appropriate clean lubricant, and the dust seal ring shall be coated with appropriate grease.
3 during installation, the surface of any sliding sealing ring must be smooth and undamaged. If the seal slides on a shaft with grooves, keyways or holes, use a special installation tool. Special tools shall not be made of soft metal (such as aluminum) or notch installation tools.
4 when installing the framework oil seal, pay attention to the side with the lip facing the pressurized oil. During assembly, maintain uniform speed and pressure to prevent the spring from falling.
5 the perpendicularity of the device must be ensured by pressing the sealing ring on the end face of the cavity hole or the bottom end face of the hole shoulder of the cavity.
6 when the sealing ring is installed in winter or low temperature environment, the sealing ring can be placed in the same cleaning solution with the sealing medium below 50 ℃ for 10-15 minutes to restore the elasticity of the lip of the sealing ring.
7 the rubber oil seal cannot be cleaned with gasoline, diesel or kerosene because the type of rubber and the oil resistance of additives are different. If there is oil on the oil seal, clean it with clean cotton thread.
8. It must be smooth during installation. It cannot be hammered or leveled. If it is difficult to install, press the rubber oil seal lip into the lip gradually.
9 when replacing the failed seal with a new seal, the edge of the new seal shall not coincide with the previous rotation path, but the edge of the new seal must be closer to the side of the sealing liquid. This is achieved by installing washers, replacing bushings and slip rings, and changing the depth of the pressure hole.
