The influence of seal pressure difference on mechanical seal performance:

Sealing pressure difference refers to the pressure difference between the sealed medium and the back pressure of the mechanical seal (the pressure involved in this article refers to the gauge pressure, which characterizes the difficulty of sealing to a certain extent. The higher the sealing pressure difference, the greater the difficulty of sealing. As shown in Figure 3-22, when other parameters remain unchanged and the pressure difference of the mechanical seal increases, the rigidity of the fluid film and the pumping capacity of the bu.
