离心泵
1、离心泵的工作原理
水泵开动前,混流泵安装,先将泵和进水管灌满水,机械密封混流泵安装,水泵运转后,在叶轮高速旋转而产生的离心力的作用下,叶轮流道里的水被甩向四周,压入蜗壳,叶轮入口形成真空,农业混流泵安装,水池的水在外界大气压力下沿吸水管被吸入补充了这个空间。继而吸入的水又被叶轮甩出经蜗壳而进入出水管。由此可见,若离心泵叶轮不断旋转,则可连续吸水、压水,水便可源源不断地从低处扬到高处或远方。综上所述,离心泵是由于在叶轮的高速旋转所产生的离心力的作用下,将水提向高处的,故称离心泵。







混流泵
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 and 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 and 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, and it can run sequentially.


轴套用来保护轴不使它与填料直接摩擦,若长期使用中发现轴套磨损过多,必须换轴套。
IV. Axile sleeve is used to protect the axle from friction
with 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.
