Side mixing mechanical seal Operating principle and sealing requirements of the manufacturer

The working principle and sealing requirements of the side mixing mechanical seal. The side mixing mechanical seal is a shaft seal that can prevent leakage by one or more pairs of end faces that slide relative to the shaft under the effect of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and is equipped with auxiliary seals. It is also called the end face seal. It has reliable performance, small leakage, long service life, and low power consumption, It does not need frequent maintenance, and can meet the sealing requirements of production process automation, high temperature, low temperature, high pressure, vacuum, high speed and various highly corrosive media, solid particle containing media and other harsh working conditions, such as centrifugal pumps, centrifuges, reactors, compressors and other equipment.

Side mixing mechanical seal

When the side stirring mechanical seal is working, the axial force caused by the pressure of the sealing fluid and the elasticity of the elastic element makes the moving ring and the stationary ring stick to each other and move relatively. Because of the close cooperation of the two sealing faces, a small gap is formed at the junction between the sealing faces. When the pressurized medium passes through this gap, a thin liquid film is formed, which produces resistance and prevents the medium from leaking, At the same time, the liquid film lubricates the end face. This liquid film has hydrodynamic pressure and static pressure, plays the role of lubrication and pressure balance, and produces long-term sealing effect.
