机械密封由于本身所具有的优点近来已得到了越来越广泛的应用,而且随着回转式流体输送机械的不断发展,对密封性能和使用寿命也提出了越来越高的要求,尤其是在高压力、高转速的情况下,要保证机械密封具有良好的密封性能和长久的使用寿命,设计最佳摩擦工况和选择合适的端面摩擦副材料及机械密封结构就成了十分重要的一环。而决定端面摩擦工况和摩擦副材料及机械密封结构适用条件的最重
Recently, mechanical seals have gained more and more widespread application due to their own advantages. With the continuous development of rotary fluid conveying machines, more and more high requirements are placed on the sealing performance and the service life. In particular, High pressure, high speed of the case, to ensure that the mechanical seal has a good sealing performance and long service life, the design of the best friction conditions and the choice of suitable end friction materials and mechanical seal structure has become a very important part . And decided to face friction and friction materials and mechanical seal structure of the most applicable conditions
