Closing force and opening force of mechanical seal:

Closing force and opening force. Figure 1-8 shows the forces acting on the compensation ring in the axial direction. The forces acting on the compensation ring caused by the sealing fluid pressure of the mechanical seal and the force of the elastic elements make it close to the non-compensation ring. These forces are collectively referred to as Closing force. which is:

Figure 1-8 shows the force acting on the compensation ring in the axial direction, as well as the force acting on the non-compensating ring in the axial direction. In the mixed friction state, the fluid film load and contact load on the seal end face act on the compensation ring to make it tend to open for the non-compensation ring. These forces are collectively called the opening force.

M37G mechanical seal uses the opening force of the seal end face to divide by the area of u200bu200bthe seal ring 4 to obtain the unit opening pressure of the seal end face. When the closing force of the sealing end face of the mechanical seal is balanced with the opening force F, that is

It can maintain the sealing balance of the end face of the mechanical seal and minimize leakage.　　534.html,
