Requirements and installation considerations for sealing ring devices

The sealing ring is the most important and effective means to solve the leakage problem of hydraulic system. If the sealing ring of the hydraulic system is poor, the sealing ring may not be allowed to leak out, and the leaking oil will pollute the environment; It may also cause air to enter the oil absorption chamber, affecting the 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 device is very important in the design of the hydraulic system, the sealing ring device requirements are as follows:

1. The sealing ring should have good sealing performance in the working pressure and a certain temperature range, and can automatically improve the sealing performance with the increase of pressure.

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, not easy to age, long working life, good wear resistance, and can automatically compensate to a certain extent after wear.

4. Simple structure, easy to use and maintenance, so that the sealing ring has a longer life.

Install Precautions Edit this paragraph
1. Clean the installation position;

2. Remove burrs during the installation and movement of seals;

3, smear lubricant on the seal;

4, protect the sealing surface from damage;

5. Check and confirm that the size of the seal is correct;

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