Heat transfer oil pump oil seal how to solve

1, master and identify the basic knowledge of shoddy products, buy high-quality, standard oil seals.

2. When installing, if the shaft surface roughness is low or there are rust, rust, burr and other defects, use a fine emery cloth or oil stone polished smooth; apply oil or grease to the oil seal lip or shaft diameter corresponding position. The outer seal of the oil seal is coated with a sealant, and the keyway portion of the shaft is wrapped with stiff paper to avoid scratching the lip of the seal, and the oil seal is rotated inward with a special tool. The hard seal cannot be used to prevent deformation of the seal. Or break the spring and fail; if there is a lip flange, spring off and oil seal skew must be removed and re-installed. It should be noted that when the shaft diameter is not worn and the spring force of the oil seal spring is sufficient, do not tighten the inner spring without authorization.

3. Oil seals applied to agricultural machinery generally require inspect, maintenance and maintenance when the working conditions are generally poor, the temperature difference between the environment is large, the dust is excessive, and the vibration of the implement frequently causes changes in the mechanical conditions of the components.

4, if the shaft diameter and bearing wear serious; oil seal rubber aging or spring failure, etc., should be repaired and replaced the corresponding parts.

5, the abnormal heating components or assemblies should be promptly troubleshooting; to avoid mechanical overspeed, overload operation, to prevent the oil seal lip temperature, rubber aging, early wear lips and so on.

6, always check the oil level, if there is too much oil impurities, there are alloy powder, metal scrap iron to completely replace the new oil. The brand and quality of the replaced oil must meet the requirements of the season.

7. Oil seals that are not used temporarily should be properly kept from oil, dust or sun exposure.

8, when the shaft diameter wear into a "V"-shaped groove, so that the new oil seal lip and shaft contact pressure can not play a sealing role, you can use AR-5 a two-component adhesive Glue, both simple and reliable and wear . Oil seal displacement can also be used to make up for.
