各位 분들에게屏蔽泵口环磨损为什么对轴向力有影响吗? 영향의 정도는 얼마나 되나요? 감사합니다.

四. 口环磨损了,压力就会变化,轴向力就会变化

二. 口环能磨损说明,石墨轴承已经磨损很严重了,合金轴承套与石墨轴承间隙发生变化,压力出现变化,推力盘平衡轴向力的能力变化了。 每次开屏蔽泵的瞬间,轴向力都是从不规则不平衡到平衡的一个过程,比过程不平衡时期,会使推力盘与石墨轴承推力面相磨,轴套与石墨轴承相磨。直到平衡后转子浮起来,无动静摩擦。每次停泵时无轴向力也是从平衡的状态向不平衡的状态变化,同理也会出现摩擦。泵运行时流量波动也会出现轴向力不平衡的状态。所以不是口环磨影响的轴向力。而是轴向力影响了磨口环。
