 The anti-fuel pump skeleton oil seal TCM589332 isolates the anti-fuel pump that needs to be lubricated in the transmission parts from the external environment, so that the anti-fuel oil will not leak. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. The working principle of TCM589332 skeleton oil seal of fire-resistant fuel pump: Because there is an oil film between the oil seal and the shaft, which is controlled by the edge of the oil seal, this oil film has the characteristics of fluid lubrication. Under the action of the surface tension of the liquid, the rigidity of the oil film just makes the contact end of the oil film and the air form a crescent surface, thereby preventing the leakage of the working medium and realizing the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak oil. If the thickness is too small, dry friction may occur, causing the oil seal and shaft to wear; if there is no oil film between the seal lip and the shaft, it is easy to heat and wear.
