吸不上水
原因是泵体内有空气或进水管积气,或是底阀关闭不严灌引水不满、真空泵填料严重漏气,闸阀或拍门关闭不严。排除方法:先把水压上来,再将泵体注满水,然后开机。同时检查逆止阀是否严密,管路、接头有无漏气现象,如发现漏气,拆卸后在接头处涂上润滑油或调合漆,并拧紧螺丝。检查水泵轴的油封环,如磨损严重应更换新件。管路漏水或漏气。可能安装时螺帽拧得不紧。若渗漏不严重,可在漏气或漏水的地方涂抹水泥,或涂用沥青油拌和的水泥浆。临时性的修理可涂些湿泥或软肥皂。若在接头处漏水,则可用扳手拧紧螺帽,如漏水严重则必须重新拆装,更换有裂纹的管子;降低扬程,将水泵的管口压入水下0.5m。
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
