The sealing ring installation requirements 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 bad, 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 stability 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 the sealing performance should automatically improve 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, has good wear resistance, and can automatically compensate to a certain extent after wear.

4. The structure is simple, and it is easy to use and maintain, which makes the sealing ring have a longer service life.

Installation precautions Edit this paragraph 

1. Clean the installation location;

2、Remove burrs during seal installation;

3、Apply lubricant to the seals;

5、Check to make sure the seal is the correct size;

6、For seals that require deformation during installation, use the corresponding tools for installation.
