Fluid lubrication and dynamic and static pressure seals of mechanical seals:

The main content of the fluid lubrication theory that replaces imported mechanical seals is fluid film lubrication. The film formation theory is carried by the fluid film to keep the seal and lubrication.

The foundation of the present theory of film formation is the flow of narrow-slit viscous fluids, and its main governing equation is the simplified Navier-Stokes equation, that is, the Reynolds equation.　　420.html,
