D12-25X3离心泵AD12-25X3如生命故障四
达不到设计流
原因:1.有空气吸入 2.由于水位降低.淹没深度不够 3.叶轮内有异物堵塞 4.转子部分严重磨损
解决方法:1.检査漏气部位并排除 2.延长吸水管.加深淹深度 3.拆卸并滴除异物 4.更换密封环
D12-25X3离心泵AD12-25X3如生命故障五
泵消耗功率过大
原因:1.填料压得过紧.并发热 2.流置过大 3.回转体与壳体有碰擦 4.泵轴承磨损 5.泵轴弯曲
解决方法:1.适当放松填料压力 2.关小闸阀开度 3.修整回转体与壳体位置 4.更换轴承 5.更换或校正
D12-25X3离心泵AD12-25X3如生命故障六
泵振动加大
原因:1.叶轮局部有堵塞 2.叶轮破损 3.流过小 4.泵轴与电动机不同心 5.轴承破损 6.混入空气.发生汽蚀
解决方法:1.拆卸清除异物 2.更换叶轮 3.稍开出口阀 4.定点找正 5.改变吸入位.改善吸水管
