故陣现象
|
可能产生的原因
|
解决方法
|
水泵不吸水压力表和真空表指针剧烈跳动
|
1.灌注引水不够
2.管路与仪表联接处漏气
3.吸程过高
|
1.检查底阀是否漏水.再雇足引水
2.拧紧漏气处
3.降低吸水高度
|
水泵不吸水真空表表示高度真空
|
1.底阀没有打开或己堵塞
2.吸水管路阻力太大
3.过滤器堵塞
|
1.检査底阀
2.更换吸水
3.清理过滤器
|
压力表有压力但仍不出水
|
1.出水管阻力太大
2.旋转方向不对
3.出口管阀门未开
4.叶轮堵塞
|
1.检査或缗短水管
2.检査电机.两相互调
3.打开出口阀
4.清除叶轮内的污物
|
达不到设计流量
|
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
|
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.更换密封坏
|
泵消耗功率过大
|
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
|
1.适当放松
2.关小闸阀开度
3.修 整
4.更换轴承
5.更换或校正
|
泵振动加大
|
1.叶轮局部有堵塞
2.叶轮破损
3.流量过小
4.泵轴与电动机不同心
5.轴承破损
6.混入空气.发生汽蚀
|
1.拆卸清除异物
2.更 换
3.稍幵出口阀
4.定点找正
5.更 换
6.改变吸入位.改善吸水管
