The water pump mechanical seal refers to a device installed and operated in the pump equipment to play a dynamic sealing role to prevent the fluid medium in the pump volute from flowing out of the pump through the pump shaft.

Since the water pump mostly transports fluid medium, it has the characteristics of horizontal installation, high speed, high pressure, solid particles, and strong corrosiveness. Therefore, the main material of the water pump mechanical seal often needs to resist the erosion and impact of solid particles and the seal caused by high speed. Due to the influence of unfavorable factors such as high-temperature abrasion on the surface, unstable sealing parameters caused by high pressure, and corrosion of the base structure, high requirements for the sealing material of the water pump mechanical seal are required. Usually, the optional material of the sealing surface friction pair is nickel-based cemented carbide. , cobalt-based cemented carbide, pressureless sintered silicon carbide, reactive sintered silicon carbide, impregnated metal graphite, PTFE-filled graphite, PTFE-filled glass fiber, special aluminum oxide ceramics, etc.; the substrate material is optional For 2Cr13 stainless steel, 301 stainless steel, 304 stainless steel, 316 stainless steel, 316L stainless steel, 904L stainless steel, PTFE, etc.; optional materials for spring compensation parts are Hastelloy, 1Cr18Ni9Ti, 3Cr13, etc.;

Different from the mechanical seal used in the kettle, the sealing medium of the water pump mechanical seal is mostly liquid, solid-liquid mixture and atmospheric gas, etc.; while the mechanical seal used in the kettle is mostly used to seal high-pressure gas or gas-liquid mixture, and leakage will cause serious damage to the environment and organisms. threaten. The water pump mechanical seal is one of the basic mechanical components with precision and complex structure and is a key component of pump machinery. Its sealing performance and service life depend on many factors, such as model selection, machine accuracy, correct installation, use, etc. There are many types of water pump mechanical seals. Different models, its maintenance is also difficult to distinguish and judge.
