Metric double lip oil seals principle: because there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has the characteristics of fluid lubrication.Tension at the surface of the liquid.
Under the action of, the stiffness of the oil film just makes the oil film and the air contact end form a crescent, preventing the leakage of the working medium, so as to achieve the seal of the rotating shaft.The sealing ability of oil seal depends on the thickness of oil film on the sealing surface.If the thickness is too small, dry friction may occur, causing oil seal and shaft wear;There is no oil film between seal lip and shaft, it is easy to cause heat, wear.
Therefore, in the installation, must be coated with some oil on the metric double lip oil seals ring, at the same time to ensure that the skeleton oil seal and the axis line is vertical, if not vertical, oil seal seal lip will drain oil from the shaft, also lead to excessive wear of the seal lip.During operation, the lubricant inside the shell slightly exudes to achieve the optimal condition of forming an oil film at the sealing surface.
