5、水泵有杂音或振动
there is noise
in pump/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 cct 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/change the bearing
3.do the static balancing test&adjust
it
4.tighten it
5.check the pump unit
6.remove the sundries
7.reduce the installation site to reduce
the installation ht=
8. remove the sundries
3.
installation base:the soil texture should be firm&solid.
4.
during installation，大流量混流泵销售价， keep the pump axile in horizontal p ition.
5.the end of
water inlet pipe should be immersed under water in about one meter&far away
from the end of mud in about half meter.
6.after installing the pump，浏阳市混流泵，calculate the
suitable suction ht=&head.under the stable water level condition，大流量混流泵价格，
二泵盖是泵与进水管相连的零件，其端面与叶轮之间留有规定的轴向端面间隙在消除轴承轴向活动间隙以后，保持规定的轴向间隙。间隙过小产生磨擦，过大则会导致泵内压力水回流，使泵的效率降低，大流量混流泵安装，通过增减调整纸垫达到规定的间隙。
ii. pump cover is
the part connected with water inlet pipe.there is an stated axial end face gap
between its end
face and
impeller(keep the stated axail gap after removing the bearing axial movable
gap).friction will be
produced if
the gap is too small， contrary， if the gap is too large， the pressure water in
pump will reflux which
makes the
feeiciency reduced.adjust the - washer&make the gap be stated one.
