What is the outline of a mechanical seal pump?

The mechanical seal pump refers to the device that is installed and operated in the pump type device to function as a dynamic seal, and avoids the fluid medium in the pump volute from flowing out of the pump through the pump shaft.

Because the water pump is mostly for conveying fluid medium, it has the characteristics of horizontal installation, high rotation speed, high pressure, solid particles and strong corrosiveness. Therefore, the mechanical seal body material of the pump often needs to resist the impact of solid particles and the sealing caused by high speed. The high-temperature abrasion, high-pressure sealing parameters are unstable, the base structural parts are corroded and other unfavorable factors, and the mechanical seal sealing material is required. Generally, the sealing surface friction pair is made of nickel-based hard alloy and cobalt. Base hard alloy, pressureless sintered silicon carbide, reactive sintered silicon carbide, metal immersion graphite, polytetrafluoroethylene filled graphite, PTFE filled glass fiber, aluminum oxide special ceramics, etc.; base material can be selected as 2Cr13 Stainless steel, 301 stainless steel, 304 stainless steel, 316 stainless steel, 316L stainless steel, 904L stainless steel, PTFE, etc.; spring compensator can be selected from Hastelloy, 1Cr18Ni9Ti, 3Cr13, etc.;

Different from the mechanical seal of the kettle, the sealing medium for the mechanical seal of the pump is mostly liquid, solid-liquid mixture and atmospheric gas; while the mechanical seal for the kettle is mostly used to seal high-pressure gas or gas-liquid mixture, and the leakage will cause serious damage to the environment and living things. Threat.

The mechanical seal of the pump is one of the mechanical basic components with precise and complicated structure, and is a key component of the pump machinery. Its sealing performance and service life depend on many factors, such as selection, machine accuracy, proper installation and use. There are a wide variety of mechanical seals for pumps. Different models, its maintenance is also difficult to distinguish and judge.
