The rotary docking sealing method is a commonly used sealing method in the industrial field, which can effectively prevent fluid or gas leakage and ensure the normal operation of equipment. This article will provide a detailed introduction to the definition, working principle, advantages and disadvantages, and application scope of the rotary docking sealing method.
1、 Definition of rotary docking sealing method
The rotary docking sealing method is a method of achieving sealing by docking between two rotating components. Common sealing methods for rotary docking include rotary mechanical seals, rotary rubber seals, and rotary metal seals.
1). Rotary mechanical seal: Rotary mechanical seal is achieved by connecting the sealing ring with the shaft sleeve or housing to achieve sealing. The inner side of the sealing ring is in contact with the shaft sleeve or journal, and the outer side is in contact with the housing. The sealing ring rotates with the rotation of the shaft and forms a seal through the docking of the sealing surface. Rotating mechanical seals have the advantages of simple structure, good sealing effect, and long service life, and are widely used in equipment such as pumps and compressors.
2). Rotary rubber seal: Rotary rubber seal utilizes the elasticity of rubber material to achieve sealing. Rubber seals form a seal by docking with the shaft or housing. The seal has good elasticity and wear resistance, and can adapt to certain shaft offsets and vibrations, resulting in a good sealing effect. Rotating rubber seals are widely used in equipment such as automotive engines and construction machinery.
3). Rotating metal seal: Rotating metal seal utilizes the plasticity of metal materials to achieve sealing. Metal seals form a seal by docking with the shaft or housing, and have good high temperature and pressure resistance, suitable for sealing under harsh working conditions such as high temperature and high pressure. Rotating metal seals are widely used in fields such as aerospace and petrochemicals.
2、 Advantages and disadvantages of rotary docking sealing method
1). Advantages:
The rotary docking sealing method has the characteristics of good sealing effect, strong wear resistance, and long service life. It can adapt to certain shaft offset and vibration, and is suitable for sealing requirements under different working conditions. At the same time, the rotary docking sealing method has a simple structure, is easy to install and maintain, and can improve the working efficiency of the equipment.
2). Disadvantages:
The rotary docking sealing method is prone to leakage under high-speed rotation and high temperature and high pressure conditions, and corresponding measures need to be taken to improve the sealing performance. Meanwhile, the rotary docking sealing method requires regular maintenance and replacement of seals, which increases maintenance costs and workload.
3、 Application scope of rotary docking sealing method
The rotary docking sealing method is widely used in various industrial fields, especially in rotating equipment such as pumps, compressors, engines, and hydraulic equipment. Meanwhile, with the development of technology, the application of rotary docking sealing methods in fields such as new energy and aerospace is constantly expanding.
In summary, the rotary docking sealing method is a commonly used sealing method that achieves sealing by docking between two rotating components. The rotary docking sealing method has the advantages of good sealing effect, strong wear resistance, and long service life, but it is prone to leakage under some special working conditions, and corresponding measures need to be taken to improve it. The rotary docking sealing method is widely used in various industrial fields, especially in equipment such as pumps, compressors, and engines. With the development of technology, the application of rotary docking sealing method in new energy, aerospace and other fields is constantly expanding.
