混流泵
三)密封装置是由填料函、水封圈、填料压盖和铅粉(或油浸)石棉盘根填料组成。其作用有:
1、启动时防止空气吸入泵内,起密封作用。
2、抽水时防止水从泵内过多的沿轴大量流出。
III. Sealing equipment is composed of stuffing box,
water seal, packing gland,lead

III. Sealing equipment is composed of stuffing box,
water seal, packing gland,lead powder(or oil immersed)
asbestos
packing padding.Its use is as follows:
1. When
starting, stop the pump from sucking air and realize the sealing function.
2. When
drawing water, stop the water running out through the axle from pump.


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.
深井潜水泵
首先看一下水泵此时运行的电流和平常运行时候的电流差别有多大。如果比平时运行时候小(基上就是平时电流的2\3),那么就有叶轮磨损、泵头上面的止逆阀堵塞等问题。如果和平时电流一样大,那么就是管垫漏水、管子漏水、泵体漏水等问题。如果比平时运行的时候电流大,那么基上可以确定是易损件磨损的问题。1、单级单吸离心泵老的泵型号有BA、B型单级单吸离心泵,80年代,我国根据和排灌机械实际情况,对离心泵产品进行更新换代研制工作,并生产IB型、IQ型单级离心泵系列产品,已列为标准和行业标准。另外补充一点,电缆如果破损的话,水量跟平时是一样大,但是电流会变大。3相380V电机的电流一般是2.2A。以上原因只要是经常维修深井泵的修理人员就可以查出来。
