- Kiểm tra và bảo trì định kỳ Sau khi thay lốp, hãy kiểm tra áp suất và độ bám của lốp thường xuyên để đảm bảo an toàn.
- 3. Clean the surfaces where the new gasket will be installed.
- Mechanical seals are another type of oil seal that relies on mechanical components to create a seal
- In conclusion, pulley oil seals, though seemingly small, play a significant role in the smooth functioning and longevity of mechanical systems. Their importance lies not just in their ability to retain lubricants and exclude contaminants but also in their contribution to overall machinery health and operational efficiency. Therefore, understanding and appreciating the value of these seals is paramount for anyone involved in the maintenance and operation of machinery that relies on pulley systems.
The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.
The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
The perfect solution to this is to always use an oil seal that fits properly; the right size of the seal should be used. And in other cases, backup devices should be used to avoid the buildup of clearance gaps within the mating edges.
