The other ways to reduce oil leakage


When installing, if the outer surface roughness of shaft diameter is low or has rust, corrosion, burr and other defects, it should be polished and smooth with fine sand cloth or oil stone. Apply cleaning oil or lubricating oil to the corresponding position of oil seal lip or shaft diameter. Apply sealant to the outer ring of the oil seal, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, rotate the oil seal inward with a special tool, do not hit the hard punch hard, and prevent the deformation of the oil seal or break the spring and fail. If the lip flanging occurs, the spring shedding and the oil seal skew must be removed and reloaded. It should be noted that when the shaft diameter is not worn out and the oil seal spring is elastic enough, do not tighten the internal without authorization Spring。

 

When the general working conditions of the oil seal applied in the machinery are bad, the environmental temperature difference is large, the dust is much, and the vibration of the machine is frequent, the stress condition of the machine parts should be checked and maintained frequently.

 

Failure of abnormal heating parts or assemblies should be eliminated in time. The mechanical overspeed and overload operation should be avoided in order to prevent oil seal lip temperature rising, rubber aging, lip wear and so on.
