Abstract:In this paper,micro-surface morphology of the seal rings is simulated by the adaptive
correlation bining with simulation of rough surface,micro-hydrodynamic lubrication model
of face inclination is also programming with finite difference method and MATLAB
software,the calculations of fluid film pressure distribution and fluid film thickness distribution of micro-
hydrodynamic lubrication of seal rings under working condition are essfully concrete
example is calculated and detail research on the influences of face inclination on the
performance of mechanical seal face l
