skeleton oil seal supplier introduces the use of oil seals

Do you know what to pay attention to when using oil seals? Today, the editor of skeleton oil seal supplierwill take you to a brief understanding.
1. Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, low-speed shafts should use low-speed oil seals, and low-speed oil seals cannot be used on high-speed shafts, and vice versa.
2. When the ambient temperature is high, polyacrylate or silicon, fluorine, and silicon fluorine rubber should be used. And should try to lower the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used.
3. The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will be deformed when the pressure is too large. Under the condition of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.

4. The degree of eccentricity on the installation If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a "W"-shaped oil seal can be used.
5. The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.
6. Note that there should be a certain amount of lubricating oil on the lip of the oil seal.
7. Pay special attention to prevent dust from immersing in the oil seal.
The above is what the editor of skeleton oil seal supplier tells: a brief introduction to the relevant knowledge about the use of oil seals.
