Installation of sealing ring

seal ring

Because there is an oil film between the oil seal and the shaft, which is controlled by the cutting edge of the oil seal, the oil film has the characteristics of fluid lubrication. Under the action of the liquid surface tension, the rigidity of the oil film just makes the contact end of the oil film and air form a crescent surface, which prevents the leakage of the working medium and thus realizes 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; if the thickness is too small, dry friction may occur, resulting in the wear of the oil seal and the shaft; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear.

Therefore, when installing, it is necessary to apply some oil on the sealing ring and ensure that the framework oil seal is perpendicular to the axis line. If it is not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft and cause excessive wear of the sealing lip. During the operation, the lubricant in the shell slightly oozes out, so as to achieve the ideal state of forming oil film at the sealing surface.
