通过机械密封端面运动状况实验 ,讨论了机械密封端面倾斜而产生的动压效应对端面稳定的影响 ,提出动压作用下机械密封端面开启失效机理 ,分析了机械密封端面开启失效与动环密封圈摩擦力等各种因素的必然关系 The mechanical end face movement condition experiment is discussed. The dynamic pressure effect on the end face stability caused by the tilting of the mechanical seal face is discussed. The failure mechanism of the mechanical seal face opening under dynamic pressure is put forward. The failure of the mechanical seal face opening failure and the moving ring seal ring Friction and other factors of the inevitable relationship
