| Abstract: | Under high pressure and lower speed, the property about mechanical face seal with deep grooves had been given an analysis in thesis. It applied finite element method to calculate deformation of seal ring and analysised the hydrodynamic effect between seal surface through changing shape of groove, number of groove, pressure of seal medium and material of seal ring. The data were compared with the results from the experimentat and a method for designing for mechanical seal under high pressure is proposed. |
