摘　　要： 所有开裂填料盘的裂纹均发生在填料盘圆周方向,并且裂纹是沿着周向和厚度方向扩展的,通过对填料盘受力分析可知,填料盘在内压作用下两相邻填料盘之间的相对滑动量只有微米量级,因此填料盘的失效是由于微动疲劳磨损造成的,从微动疲劳寿命与无微动时拉伸疲劳应力的关系着手,确定影响微动疲劳寿命的因素。根据填料盘的工作条件,提出了减缓填料盘微动疲劳的措施,并取得了较好的效果。 The crack cause in the circle of packing box and the expansion of the crack of the packing box in the thickness and the depth direction, and packing box slippage is only micron degree by internal air pressure effect, with this end in view, the failure of packing box was fretting fatigue and fretting wear. Define infection fretting fatigue life factor, according as the relation of fretting fatigue life and tension stress without fretting. And carry out scientific processing method based on working states, and the method is effective.
