1、水泵不出水
No water are
runing out
1、引水不够真空泵抽吸空气不尽
2、进水管路进气
3、水泵转速太低
4、吸程太高
5、水泵转向不对
6、输水高度超过规定
1.The diversion is not engouth or the
vacuum pump does not remove all air
2.Air suction for inlet pipes
3.The rotate speed of pump is too low
4.Suction head is too high
5.The turnning direction is not right
6.Water delivery height exceeds stated
one.
1、继续加灌或抽气
2、检查并堵塞之
3、用转速表检查予以调整
4、降低安装位置减少吸程
5、改变旋转方向
6、减少输水高度
1.Continue filling or removing air
2.Check and seal it
3.Check by tachometer and adjust it
4.Reduce the installation po ition,
reduce the suction head
5.Change the turnning direction
6. Reduce water delivery height
7、填料发热
The padding is
hot
1、填料压得太紧或四周紧密度不够2、填料压得偏斜与轴磨损严重
1.The padding is
pressed too tight or the around compactness is not enough
2.The padding is
pressed deflected and the axile wears seriously
1、旋松压盖螺栓高速填料紧密度
2、松开压盖重新均匀地上紧
1.Loosen the gland bolts to adjust
2.Loosen the gland bolts and tighten it again.
8、填料处漏水太多
leaking water too much
1、填料压得太松
2、填料装置不好
3、填料大小不一或磨损过多
4、填料质量差，密封性不好
5、轴套磨损太多
1.The padding is pressed too loose
2.The padding does not assemble well
3.The padding is not of niform size or it
wears too much
4.The padding is with bad quality and
tightness
5.
1、上紧压盖到适应程度
2、调整填料搭口，使之错开一定角度而不在一个方向
3、更换填料
4、更换符合要求的石棉填料
5、更换轴套
1.Tighten the gland up to suitable degree
2.Adjust the padding jiont up to some
angle not in the same direction.
3.Change the padding
4.Change the suitable asbestos padding
5.Change the axle sleeve.
