of water is not enough
1、进水管路或叶轮有水草杂物
2、转速过低
3、输水高度过高
4、泵盖及叶轮磨损间隙过大
5、填料进气
6、马力不足
7、进水管口插入水中深度不够
1. There are waterweeds
排污混流泵安装
3、水泵出水量不足
The waer yield
of water is not enough
1、进水管路或叶轮有水草杂物
2、转速过低
3、输水高度过高
4、泵盖及叶轮磨损间隙过大
5、填料进气
6、马力不足
7、进水管口插入水中深度不够
1. There are waterweeds and sundries in
inlet pipes or impeller
2.The rotate speed is too low
3.Water delivery height is too high
4.The attrition gap between pump cover
and impeller is too large
5.The padding is air in
6.The horsepower is not engough
7.The depth of inlet pipe under water is
not enough
1、清除水草杂物
2、调整转数
3、降低输水高度
4、用纸垫调整间隙至正常
5、压紧或更换填料
6、加大马力
7、增加插入水中深度至一米左右
1.Clear the waterweeds and sundries
2.Ajust the rotate speed
3.Reduce the water delivery height
4.Add paper washers to adjust the gaps
5.Compact or change padding
6.Increase the horsepower
7.Make the depth of inlet pipe under
water to one meter
混流泵
5、水泵有杂音或振动
There is noise
in pump or the pump is vibrating
1、轴中心没有对正
2、轴弯曲轴承磨损过大
3、叶轮平衡性差
4、地脚螺栓松动
5、装置不当
6、叶轮局部阻塞
7、吸水高度太高、发生汽蚀
8、泵内掉进杂物
1.The axile center is not aligning
2.The axile is bend, the bearing wears
much
3.The balance of impeller is not good
4.The foundation bolts are loose
5.The assembly is improper
6.Part of the impeller is blocked
7.The suction head is too high to produce
cavitation
8.There are sundries in pump.
1、找正
2、校正或更换轴承
3、进行静平衡试验和调整
4、拧紧
5、检查机组
6、消除杂物
7、降低安装位置减低安装高度
8、清除杂物
1.Calibrate
2.Calibrate it or change the bearing
3.Do the static balancing test and adjust
it
4.Tighten it
5.Check the pump unit
6.Remove the sundries
7.Reduce the installation site to reduce
the installation height
8. Remove the sundries
用户选择水泵时， 是到农机部门认可的销售点，一定要认清生产厂家。建议优先考虑购买充水式潜水电泵，并且看清牌号和产量合格证。千万不能购买“三无”（即无生产厂家、无生产日期、无生产许可证）产品，否则出现了问题，用户将束手无策。
作为用户，由于受到知识的局限，很难定夺， 靠而又比较成熟的产品，不失为一种明智的选择。同时，应根据当地的电源情况来决定用单相泵或三相泵。
