1- Due to the exist between skeleton oil seal and the shaft seal edge control of oil film, the film with fluid lubrication properties.Under the effect of the surface tension of liquid, oil film stiffness just makes the oil film is exposed to air end to form a new moon face, prevent the leakage of working medium, so as to realize the sealing of the axis of rotation.Skeleton oil seal sealing ability, depend on the sealing surface of the oil film thickness, the thickness is too big, oil seal leakage;Thickness is too small, dry friction may occur and cause skeleton oil seal and shaft wear;No oil film between the sealing lip on the shaft, easy cause fever, wear and tear.
2- When installation, must put some oil on the seal ring, at the same time guarantee the skeleton oil seal and the vertical axis, if not vertical, skeleton oil seal sealing lip lubricating oil from the axis line to do, can also lead to excessive wear of the sealing lip.In operation, the casing of the lubricant leakage point, slightly on the sealing surface in order to achieve the most ideal forming oil film.
