Installation method of hydraulic cylinder sealing ring
1. In order to avoid possible oil leakage due to distortion. When installing the O-ring, do not pull it to the extent of permanent deformation, and do not roll it while setting it.
2. The V-shaped sealing ring is composed of a supporting ring, a sealing ring and a pressure ring with different shapes. When the pressure ring compresses the sealing ring, the supporting ring can make the sealing ring shape and play a sealing role. The opening faces the pressure oil chamber;
When adjusting the pressure ring, the oil leakage should be the limit, and the pressure should not be too tight to prevent excessive sealing resistance. For Y-shaped sealing ring, its lip should deal with pressure oil cavity; Yx-shaped sealing ring should also pay attention to the area
Do not install it wrong if it is used for shaft or hole. In addition, when installing Y-shaped and V-shaped sealing rings, pay attention to the installation direction to avoid oil leakage due to installation.
3. If the sealing device is matched with the sliding surface, a proper amount of hydraulic oil should be applied during assembly.
4. All O-rings and dust-proof rings after disassembly should be replaced with new ones.
5. When the hydraulic cylinder is installed on the main engine, a sealing ring must be added and tightened between the inlet and outlet joints to prevent oil leakage.
Finally, the test: After the assembly is completed, there should be no blockage and uneven resistance when the piston assembly moves. After the piston and the piston rod are assembled, try to measure whether the coaxiality and straightness over the full length are out of tolerance. . After being assembled as required, several reciprocating movements should be carried out under low pressure to remove the gas in the cylinder.
