Safe china oil seal design will remind you that when oil seal leakage is found, you should first confirm the location of the oil leakage. If it is not oil leakage from the oil seal, it is sometimes mistaken for oil leakage caused by reasons other than grease leakage. The main reasons for oil seal leakage:
1. Because the size tolerance does not comply with the standard specifications, the static seal surface that coordinates the outer edge of the oil seal and the cavity is deformed;
2. The material cracks are caused by the conditions of the working conditions too harsh, especially the cracks on the mouth of the oil seal and sealed blade;
3. Due to the harsh conditions of the working conditions and the incompatibility between the rubber elastic body and the working medium, the hardness of the rubber hardness is increased, or the hardness of the elastic body is too high;
4. The sealing medium causes the rubber to swell and reduce the hardness of the rubber, which makes the oil seal premature aging and wear;
5. Corrosion from the axis to the sealing lip area will leave a permanent faulty hazard to the sealing performance of the sealing system;
6. The lubricant fails and makes the system in dry operation, so that the sealing lips are worn quickly;
7. Comprehensive aging, both rubber elastic body and sealing medium are both aging;
8. “Oil and carbon” dirt is formed at the sealing lip mouth, causing the oily sealing lips to be held up, causing the leakage failure of the sealing system;
9. The sealing lip margin of the oil seal no longer follows the vibration of the axis surface and the beating of the axis;
10. Pollutants from the sealing blade from the sealing blade from the sealing inside and outside the sealing blade.
11. The irregular assembly process causes the contact surface of the shaft to be destroyed and causes the sealing lips prematurely;
12. The sealing blade is damaged during the storage, transportation and assembly process.
