1. According to the static ring located inside or outside the sealing end face, it can be divided into: internal type and external type;
2. According to the leakage direction of the sealing medium, it can be divided into: internal flow and external flow;
3. According to the logarithm of the end face of the medium, it can be divided into: single end face and double end face;
4. According to the number of springs, it can be divided into: single spring type and multiple spring type;
5. Classified by elastic elements: spring compression type and bellows type;
6. According to the non-contact mechanical seal structure classification: hydrostatic pressure, hydrodynamic pressure, dry gas seal;
7. Classified according to the temperature of the sealed chamber: high, medium, normal, and low temperature sealing;
8. According to the pressure of the sealed chamber: super high, high, medium and low pressure mechanical density.
