Oil seal of circulating pump 249499. Oil seal is a common term for general seals. In short, it is the seal of lubricating oil. It is a mechanical element used to seal grease. It isolates the parts that need lubrication and the output parts in the transmission parts, so that the lubricating oil does not leak.

Classification

The sealing function, characteristics, structure type, working state and sealing mechanism of the oil seal can be divided into various forms and different calls, but it is customary to call the lip seal ring of the rotating shaft called oil seal, the static seal and the dynamic seal (general reciprocating motion) are called seals.

Main factors causing oil seal oil leakage

Tight seal of oil seal is the main factor causing oil leakage. Even when the replacement of the new oil seal is still not sealed, it is due to the drop of contact pressure between the lip of the oil seal and the shaft, so that the diameter of the seal lip and the diameter of the shaft is too small.

(1) The quality of the oil seal is poor;

(2 )The quality of shaft or bearing is poor;

(3) Improper use and maintenance;

(4) improper installation;

(5) Improper storage and adverse effects caused by environmental pollution.
