Heat pump oil seal works: 1, free state, the oil seal lip diameter smaller than the shaft diameter, with a certain amount of interference. 2, After installation, the interference pressure of the seal edge and the contraction force of the self-tightening spring will generate certain radial pressure on the rotating shaft. 3, work, the seal lip in the radial pressure of the role of the formation of 0.25 to 0.5 mm wide seal contact zone. Under the action of the lubricating oil pressure, oil penetrates into the oil seal and forms a very thin layer of oil film between the rotating shaft. Oil film by the oil surface tension role in the shaft and the outer edge of the seal edge to form a "crescent" to prevent oil spills, play a sealing effect.
