Is oil seal leakage a problem of installation or selection
Nov 13, 2021
It is very simple to use a simple method to detect the leakage of the oil seal. First of all, we understand the condition of seals and how much you know about the choice of seals. If you have a good understanding of sealing products, I think it is already a talent. Let us first talk about oil seal installation, and then talk about the problems encountered when selecting oil seals.
Installation problems
1. The wrong installation direction of the oil seal can cause leakage.
2. During the installation process, foreign matter or dust in the pipeline enters the sealed cavity and causes leakage.
3. Poor assembly will cause damage and leakage of the oil seal.
4. Scratches on the surface of the oil seal can cause leakage.
5. The piston rod is not concentric, eccentric load will cause leakage.
The choice of oil seal
1. The pressure is too high, and the hardness of the oil seal is too small to be extruded from the metal groove.
2. The sealing material is compatible with the medium, and the sealing parts are softened or dissolved.
3. The oil seal is used in an environment where the temperature is too high and the sealing material is carbonized.
4. The low temperature causes the sealing material to harden and shrink and cause leakage.
5. The speed of using the production line is too high, leading to oil seal heating, dry grinding, carbonization and leakage.
6. Poor lubrication under working conditions will cause oil seal wear and leakage.
7. The mold cavity in use is exposed to vibration, causing leakage.
8. Leakage caused by oil seal wear caused by dust.
9. The hardness of the oil seal is too high to completely fill the metal groove, resulting in leakage.
10. The size of the oil seal does not match the metal groove, resulting in leakage.
11. Please use oil seals that have been stored for a long time and are aged to avoid leakage.
