方 法

Methods

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
