混流泵

一试车：

 水泵在安装完毕后，必须试车，其目的：

1、

使各种配合部分运转协调。

2、

检查和消除安装中的毛病。

3、

检查水泵的转向是否符合要求

i.

test run

do test run

after installation for the following purp 

1.make all

parts cooperate well.

2.check and

remove the problems during the installation.

3.check the

diversion of pump if it is up to the mustard.

开车顺序：

    1、关闭出口闸阀

    2、将水注入水泵，以排除进水管及泵内空气，可从泵体顶端引水杯注入清水，也可用真空泵注水开动真空泵，排除水泵及管内气体在水充满水泵的同时，起动水泵，打开闸阀，停止真空泵。

3、开启电动机注意水泵的旋转方向。

    4、当电动机正常运转后，逐步开大闸阀，达到所要求的工况后，调节填料松紧。若水泵运转，轴承温度等都正常，则可继续运行。

iii.  starting

sequence

   1.close the oulet

sluice valve.

   2. inject

water into pump to remove the air in water-in pipe&pump which can realized

by injecting clear water from the water diversion cup of the pump body end or

by vacuum pump(start the vacuum pump, remove the air from pump&pipes, start

the water pump when the pump is full of water, open the sluice valve, stop the

vacuum pump).

   3. start the

motor(pay more attention on the rotation direction of pump)

   4. when the motor runs normally, turn up the

sluice valve gradually, adjust the tightness of padding when gettng to the

required working condition.if the pump runs well, the temperature of bearing is

normal,&it can run sequentially.

 7、填料-

 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-

 1.the padding is

 pressed too tight/the around compactness is not enough

 2.the padding is

 pressed deflected&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&tighten it again.
