According to the characteristics of high temperature, high pressure and strong corrosion of the medium, choose metal bellows mechanical seal. Metal bellows mechanical seal has good buoyancy, auxiliary seal is easy to configure, easy to install, can use different materials and manufacturing methods, can adapt to high temperature, high pressure, strong corrosion conditions and other characteristics of the seal cooling method to improve.

The tail of the static ring is lengthened, and double sealing rings are used in the axial direction. The cooling water is fed into the middle of the rubber ejector to cool the static ring, which can not only reduce the deformation of the static ring, but also increase the safety of the two O-rings. In addition, there are cooling water jackets in the shaft seal box and bearing box to access the cooling water, no cooler is used.

The cooling method is good for the mechanical seal itself and its use. If cooling is not used, the following problems will occur: the liquid film viscosity between the end faces is reduced and vaporized, so that the liquid film is unstable or destroyed. Seals made of rubber, plastic and other materials will appear early aging and decomposition. Accelerate the corrosion of the seal by the medium. Static and static ring deformation, hot crack, impregnated metal melting. The medium pressure difference between the sealing friction pair increases, so that the end face opens and causes leakage. The bearing box temperature is too high, reducing the service life of bearings.

Selection of friction pair washing water contains H2S, even if the medium contains a small amount of H2S will also form a high concentration of hydrogen ions. The reaction is Fe + S2 -= FES ↓+ 2E, and the generated FES will be suspended in the medium as small particles. Therefore, the material of hard phase friction pair is selected carbide WC, and the hardness of tungsten carbide is HRA86 ~ 93; The thermal conductivity is 5.86 ~ 8.79 kW, which is 1 ~ 2 times higher than that of high-speed steel. The linear expansion coefficient is small, which is lower than chromium nickel stainless steel, chromium steel and carbon steel. Carbide phase of hard alloy, resistance to a variety of acid and alkali corrosion at room temperature.
