SIMPLIFIED METHOD OF CALCULATING THE OPERATING CHARACTERISTICS OF A FACE SEAL

摘要

We note that the seal can function stably in the fluid friction mode (for the chosen design characteristics of the seal unit) when the axial rigidity of the lifting layer at the contact of the parr of surfaces of the face seal ring pair is high. That rigidity is the parameter for optimizing a seal with a wedge-shaped slot. When designing the unit, the designer must strive to create a face seal with the highest attainable lifting layer rigidity in the contact of the face surfaces of the ring pair.
