What are the solutions to oil leakage from oil pump seals?

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

2. During installation, if the outer surface roughness of axle diameter is low or there are defects such as rust spot, corrosion and burr, polished with fine emery cloth or whetstone; Apply clean oil or grease to the oil seal lip or shaft diameter. 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, and the oil seal is rotated and pressed in with special tools. Never smash the oil seal hard to prevent the deformation of the oil seal or squeeze the broken spring and failure; If lip flanging, spring off and oil seal skew must be removed and reloaded. It should be noted that: when the shaft diameter is not worn and oil seal spring spring enough, do not take the liberty to tighten the spring.

3, the application of the oil seal on agricultural machinery in general working conditions, large environmental temperature difference, dust, frequent vibration of the machine and tools so that the mechanical stress conditions constantly change, to check, maintenance and maintenance.

4, such as shaft diameter and bearing wear seriously; The aging of oil seal rubber or the failure of spring should be repaired and replaced in time.

5, abnormal heating parts or assemblies should be timely troubleshooting; Avoid mechanical overspeed and overload operation to prevent oil seal lip temperature rise, rubber aging, early lip wear, etc.

6, always check the oil level, if there are too many impurities in the oil, alloy powder, metal scrap to completely replace the oil. The brand and quality of the oil to meet the requirements of the season.

7, temporarily unused oil seal, should be properly kept, to prevent grease, dust or sun exposure.

8, when the shaft wear into "V" 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 bonding, both simple and reliable and wear-resistant. Oil seal displacement can also be used to compensate
