The installation requirements of the sealing ring are the most important and effective means to solve the leakage problem of the hydraulic system. If the sealing ring of the hydraulic system is not good, the sealing ring may leak out unacceptably, and the leaked oil will pollute the environment; it may also allow air to enter the oil suction chamber, affecting the working performance of the hydraulic pump and the smoothness of the movement of the hydraulic actuator. Therefore, the reasonable selection and design of the sealing ring installation is very important in the design of the hydraulic system. The requirements for the sealing ring installation are as follows:

1. The sealing ring should have good sealing performance within the working pressure and a certain temperature range, and can automatically improve the sealing performance as the pressure increases.

2. The friction between the sealing ring device and the moving parts should be small, and the friction coefficient should be stable.

3. The sealing ring has strong corrosion resistance, is not easy to age, has a long working life, good wear resistance, and can automatically compensate to a certain extent after wear.

4. The structure is simple, easy to use and maintain, so that the sealing ring has a longer life.

Installation precautions Edit this paragraph 1. Clean the installation location;

2. Remove burrs during the installation of the seal;

3. Apply lubricant to the seal;

4. Protect the sealing surface from damage;

5. Verify that the size of the seal is correct;

6. Use the corresponding tools to install seals that need to be deformed for installation.
