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，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。

泵体与叶轮口环磨损的话会泄压，首先扬程下降，其次前后压力发生变化，轴向力会推向压力较小的一方，需要专业维修厂家调整，15242535301
