The mechanical seal (mechanical seal) is a device for preventing fluid leakage, which is composed of at least one pair of end faces perpendicular to the rotation axis, and the end faces are kept in contact and relatively slide under the action of fluid pressure and the elastic force (or magnetic force) of a compensation mechanism and the matching of an auxiliary seal.
The elastic loading mechanism and the auxiliary seal are mechanical seals of metal corrugated pipes, which are called metal corrugated pipe seals. In light sealing, a rubber corrugated pipe is used as auxiliary sealing, the elasticity of the rubber corrugated pipe is limited, and a spring is generally required to be supplemented to meet the loading elasticity. "mechanical seal" is often referred to by one as "mechanical seal" for short.
The mechanical seal is a shaft seal device of a rotating machine. Such as centrifugal pumps, centrifuges, reaction kettles, compressors, and the like. Since the rotating shaft penetrates inside and outside the apparatus, so that there is a circumferential gap between the shaft and the apparatus through which the medium in the apparatus leaks to the outside, and if the pressure in the apparatus is lower than the atmospheric pressure, air leaks into the apparatus, a shaft sealing device for preventing the leakage is necessary. The shaft seal has many kinds, and the mechanical seal has the advantages of small leakage amount, long service life and the like, so the mechanical seal is the most important shaft sealing mode in the devices in the world.
