Working principle and sealing requirements of side stirring mechanical seal manufacturers

The working principle and sealing requirements of the side stirring mechanical seal. The side stirring mechanical seal relies on a pair or several pairs of end faces that are perpendicular to the shaft for relative sliding under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism. The shaft seal device that seals to prevent leakage, also called end face seal, has reliable performance, small leakage, long service life, low power consumption, no frequent maintenance, and can adapt to the automation of production process and high temperature, low temperature, high pressure, vacuum, high speed And the sealing requirements of various strong corrosive media, media containing solid particles and other harsh working conditions, such as centrifugal pumps, centrifuges, reactors and compressors and other equipment.


When the side stirring mechanical seal is working, the axial force caused by the pressure of the sealing fluid and the elastic force of the elastic element makes the moving ring and the static ring stick to each other and move relative to each other. A tiny gap is formed at the junction. When the pressurized medium passes through this gap, a thin liquid film is formed, which generates resistance and prevents the leakage of the medium. At the same time, the liquid film lubricates the end face. This liquid film has hydrodynamic pressure and static pressure, plays the role of lubricating and balancing pressure, and produces a long-term sealing effect.
