摘要
Abstract
Based on the structure of mosaic mechanical seal with straight deep line groove , the mathematic model was devel-oped with the seal ring and lubrication film , which solves the lubrication and deformation equation with finite difference and ele-ment method respectively .The effect of the pressure and speed on lubrication film was studied and the operating parameters on mechanical performance were analyzed .It is found that the seal face with straight deep line can form the waviness and the taper . While the pressure elevated , the waviness becomes larger , the taper is fewer changed .But it has a large effect on the waviness . While the speed increases , the waviness and taper of the seal face has less variation .The higher the pressure is , the larger the leakage and the smaller the friction coefficient .With the speed rising , the leakage changes slowly and the friction coefficient be-comes larger .关键词
