*Related Introduction*

The mechanical seal system includes pressure control, temperature control, fluid replacement (blocking) and impurity removal systems. In the same mechanical seal system, not all of the above systems are included at the same time. The choice of mechanical seal system mainly depends on the scope of use of the main seal. For example, if the main seal is used for high-temperature liquids, the sealing system must ensure that the ambient temperature of the main seal is reduced, that is, a temperature control system is adopted;If the main seal is used for the working medium with solid impurities containing Dong Gao, the sealing system must ensure that the solid impurity content is reduced before the main seal, that is, the impurity removal system; in the corrosive medium, the sealing system must ensure that the main seal is reduced Corrosion rate or elimination of corrosion, that is, the use of fluid replacement blocking fluid system; in the high-pressure sealing device, the auxiliary system should ensure multi-stage pressure reduction and other measures, that is, the use of a pressure control system.
