| Abstract: | A theoretical analysis is made on the mechanical face sealings employed in
the main shaft of a turbine working with low-boiling-temperature organic.
compounds.Applying the theory of surface waves and cavitation the hydrodyna-
mic lubrication model of the sealing is established,in which the effects of
the curvature inertia and cavitation development on the fluid flow are taken
in to account.A good double-face type of the mechanical sealing has been
successfully developed.A numerical solution of the characteristic performance
of the seal is obtained and experimental results are carried out. |
