混流泵
5、泵运转时注意有无杂音及泵内是否有剧烈的磨擦和撞击声，如有就停车检查。
When the pump is
running, pls pay more attetion on the noise and friction and clashing noise, if
there are strong noise, pls stop the pump to check.
6、检查进、出水管路有无进气漏气现象。
Check the
water-in and out pipes if they are leaking air.
7、如电机与水泵为直联传动，需检查电机与水泵的轴心线是否在同一直线上，以防转时振动。
When the motor and pump are direct
connected drive ,check the motor and pump axile lead if they are in the same
line to ***oid vibrating.
2、水泵起动后有一股水就不出水了
After starting ,
the pump only send one stream water then no water runs out
1、吸入的水中有过多气泡
2、吸水管中窝存空气
3、吸水管或连接处垫料不严密有进气现象
4、底阀或叶轮有水草杂物填塞
1.There are too many bubbles in the
indrawn water
2.There is air in the suction pipes
3.The paddings in connected parts are
imprecision and produces leaking phenomenon
4.There are waterweeds and sundries
filled in the bottom valve or impeller
1、检查进水管末端是否在水平面以下一米左右
2、排除空气
3、高速垫料，填塞缝隙拧紧螺栓
4、消除水草杂物
1.Check the end
of water inlet pipe if it is under the water surface at one meter
2. Remove the
air
3.Add padding to
fill the gaps and then tighten the bolts
4.Clear the
waterweeds and sundries.
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
c***itation
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
