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，球铁混流泵安装，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，球铁混流泵维修，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.
磁悬浮潜水电泵是新一代潜水电泵，它实现了立轴磁悬浮(在不同工况下保持---率)、不磨损，使用时间及检修周期延长-，省去频繁的定期检修工作，可连续运转数万小时，球铁混流泵，节省维修、检修费用。
潜水排污泵磁悬浮潜水电泵通过了 试验室、山东省泵类产品检测中心检测。试验数据证明，球铁混流泵销售，磁悬浮潜水电泵的转换效率超过传统潜水电泵，用户使用情况结合实验数据及领域内对比，进一步证明其---节能、转换效率 、单机扬程领 及高承载、---流量、免 修、长寿命等特点!
一hw型混流泵由泵体、泵盖、叶轮、泵轴和轴承体等主要零件构成。
