Overview of mechanical seals for pumps

As the water pump is conveying fluid medium, with the level of installation, high speed, high pressure, with solid particles, strong corrosive characteristics, so the pump mechanical seal material often need to resist the erosion of solid particles impact, high speed of sealing surface caused by high temperature abrasion, high pressure to bring the sealing parameters instability, Matrix structure of the corrosion and other adverse factors, the mechanical seal sealing material requirements are high, usually the sealing surface friction pairs of optional materials are nickel-based cemented carbide, cobalt-based cemented carbide, sintered silicon carbide, reactive sintered sic, metal impregnated graphite, PTFE filled graphite, PTFE filled glass fiber,

Alumina special ceramics and so on; The matrix material can be selected as 2cr13 stainless iron, 301 stainless steel, 304 steel, 316 stainless steel, 316L stainless steel, 904L stainless steel, PTFE, etc., the spring compensation parts can be selected materials for the HA alloy, 1Cr18Ni9Ti, 3cr13 and so on;

Unlike the mechanical seal of the kettle, the sealing medium for the mechanical seal of the pump is liquid, solid liquid mixture and atmospheric pressure gas, and the mechanical seal of the kettle is used for sealing high-pressure gas or gas-liquid mixture, and the leakage will pose a serious threat to the environment and organism. Pump mechanical seals belong to the precision, the structure of more complex mechanical base components, is the pump machinery key components. Its sealing performance and service life depends on a number of factors, such as selection, machine accuracy, correct installation and use. Pump mechanical seals a wide range. Models vary, and its maintenance is difficult to distinguish and judge.
