In the process of using high temperature heat conduction oil pump, oil seal leakage may be the most common situation, the following is a brief description of the solution:
1, often check the oil level, if the oil impurities are too much, there are alloy powder, metal iron filings to completely replace the new oil.
2, the abnormal heating parts or assembly should be timely troubleshooting; Avoid mechanical overspeed, overload operation, to prevent oil seal lip temperature rise, rubber aging, lip early wear and so on.
3, such as serious shaft diameter and bearing wear; Heat conduction oil pump oil seal rubber aging or spring failure, should be repaired and replaced in time.
4, temporarily unused oil seal, should be properly kept, to prevent oil, dust or sun exposure.
5. Master and identify the basic knowledge of shoddy products, buy high-quality and standard oil seals, and also go directly to Botou gear oil pump factory to buy directly.
6, installation, if the shaft diameter surface roughness is low or rust, rust, burr and other defects, to use fine emery cloth or whetstone polished smooth; Apply cleaning oil or lubricating grease to the corresponding position of oil seal lip or shaft diameter. 7, when the shaft diameter wear into "V" shaped groove, so that the new oil seal lip and shaft contact pressure drop can not play the role of oil sealing, can choose AR a 5 two-component adhesive adhesion, both simple and reliable and wear-resistant. The brand and quality of the oil should meet the requirements of the season. The outer ring of the oil seal is coated with sealant, and the key slot on the shaft is wrapped with hard paper to avoid scratching the lip of the oil seal. The oil seal is rotated and pressed inward with special tools, and must not be hard hit and hard rushed to prevent the deformation of the oil seal or the failure of the spring; If there is lip flanging, spring off and oil seal askew must be removed and re-loaded.
.
8. When the oil seal applied in agricultural machinery has bad working conditions, large temperature difference, dust and frequent vibration, the mechanical parts should be inspected, maintained and maintained frequently. Oil seal displacement can also be used to compensate. It should be noted that when the shaft diameter is not worn and the oil seal spring is enough, do not tighten the inner spring without authorization.
The above is botou City Haina Oil Pump Co., Ltd. to solve the high temperature heat conduction oil pump oil seal leakage method.
