There are mainly the following materials for China mechanical sealing:
1. Carbon material: suitable for low temperature, low pressure and sulfur -free media.
2. Ceramic materials: suitable for high temperature, high pressure and strong corrosive media.
3. Metal material: suitable for high -speed and high -voltage media, such as the sealing site of high -speed pumps.
4. Rubber material: It is suitable for the sealing medium to water and oil, and the cover can have a certain swing.
Principles of China Mechanical Sealing Selection:
1. According to the physical and chemical attributes of the medium, choose the material of corrosion resistance and wear resistance;
2. According to the temperature and pressure of the medium, select materials that can withstand high temperature and high pressure;
3. According to the working status of the sealing environment, choose materials with good wear resistance and have certain elasticity;
4. While choosing a sealing material, it is necessary to consider factors such as easy processing, cost, and service life.
