When the side mixing mechanical seal work, the axial force caused by the pressure of the sealing fluid and the elastic element of the elastic element, and the alternating ring and the static ring are mounted and relatively movement, due to the close cooperation of the two sealing end faces, the sealing end surface The junction forms a minute gap. When the compression medium passes this gap, a thin liquid film is formed, producing resistance, preventing the medium leakage, and the liquid film further enables the end surface to be lubricated. This layer of liquid film has fluid dynamic pressure and static pressure, which plays a lubrication and balanced pressure, while generating long-term sealing effects.
