1、检查地脚螺栓的坚固情况。
2、检查传动皮带松紧程度及安装设备是否安装妥善。
3、检查进、出水管是否进气、漏水。
4、检查填料松紧是否适宜。
5、检查电动机和水泵轴心线是否在同一直线上,直联时,混流泵销售,电动机旋转方向是否符合泵的旋转方向。
6、检查泵内有无障碍,轴是否卡住,排污混流泵销售,用手转动应轻无杂音。
ii. preparation before starting
1. check the foundation bolts if they are firm.
2. check the degree of tightness of drive belt and check the
installation if it is suitable.
3.check the water–in and outpipes if they are leaking water andair.
4.check the degeree of tightness of padding if it issuitable.
5.check the
motor and pump axile lead if they are in the same line and checkthe direction
of rotation of motor if it is the same with the rotationdirection of pump.
6.check the
pump if there are barriers , if the axile locks, there should beno noises when
turing it by hand.
iv. axile sleeve is used to protect the axle from friction
with padding.in long term using, change the axile sleeve
when the sleeve wears down too much.
(五)水泵轴的两个支承是轴承体内的轴承,轴承体内存有适量润滑脂以润滑轴承。
v. two supportings of water pump axile are bearings in
bearing body.there is some lubricating grease in bearing
body for lubricating bearing.
4、耗用功率太大
the power
cumption is too large
1、转速太高
2、传动轴弯曲
3、填料压得太紧
4、轴承磨损或损坏
5、叶轮和前盖摩擦
6、皮带太紧
1.the rotate speed is too high
2.the drive shaft is bend
3.the padding is too tight
4.the bearing is worn out
5.impeller clashes the front cover
6.the belt is too tight
1、降低转速
2、校直
3、拧松压盖螺栓或将填料取出打扁一些
4、更换轴承
5、调整叶轮端面轴向间隙
6、适应放松
1.reduce the rotate speed
2.straightening
3.loose the cap blot or take our the
padding and make it more flat
4.change the bearing
5.ajust the end play of impeller end face
6.loose the belt to suitable degree
