摘要(Abstract):

对激光加工的多孔端面机械密封进行了摩擦性能试验研究 ,并与一般机械密封进行比较。结果表明 ,其端面温升、摩擦扭矩和摩擦系数远低于后者的相应值。说明该密封结构产生的动压效应使密封面间处于良好的摩擦状态
The tribological aspect of the laser textured mechanical seals with micro pores is investigated. Compared with the conventional mechanical seals, temperature rise, friction torque and friction coefficient of the laser textured mechanical seals with micro pored are much lower. The results show substantial hydrodynamic effects and better friction condition between two seal faces.
