Fluid film stiffness of parallel plane seal of mechanical seal

　2017-06-12　　

The fluid film stiffness of the parallel plane seal of the mechanical seal is:

Because, the axial stiffness of the fluid film on the simple parallel end faces of the Flygt mechanical seal is equal to zero, that is, the thickening or thinning of the fluid film will not affect the force of the fluid film, so that the purpose of automatically adjusting the gap cannot be achieved. Therefore, in terms of ensuring rigidity, the parallel plane is particularly useful, as it seems to be a component of other step surfaces, groove surfaces and other seals.　　439.html,
