"un pompe centrifugeuge avec un de d 36 m m m d'écou 3e3 m m 介质清水量电流33 一次停机后再开只有18电流 "检查水泵没问题A进水阀是蝶阀没问题A止回阀阀板都取了A应该是出水阀门掉板A送不出水A 扩手动开出水电动阀A泵会反转。而且闸阀门的时候填料处漏水说明阀板是能打开一点的为什么闸阀门出现掉板的情况还能开一点点呢如果阀门没掉板为什么开泵又送不出水

"c'est une manifestation典型现象因为这是闸阀阀杆严重腐蚀的结果这是因为新的闸阀（一般讲双闸板）阀杆端部有个大头这个大头的厚度也制约了两个闸板的最小宽度而腐蚀以后变窄所以盘根部位泄露严重全部开启后因为受到闸板另一端密封面的制约一般泄露较小也就是说没开或者开了一小部分闸阀是会泄露的也许泄露更厉害

"问题为什么只能开一点点闸阀应该掉板了他为什么能开一点点不能全开这个泄漏的现象说明闸阀开了一点但是开泵完全没流量 " "泄不能说明开了闸阀要旋转很大距离闸板才能到达开启位置开不开是因为阀杆腐蚀严重所致拿下焊接好可以再用用有问题
