电潜泵由于其开关的特性,所以都不宜采用反复操作(时开时停)。按正常方法,启动电流有时会比工作电流大5～8倍。这种波动容易损坏电动机和电缆,还会引起线路电压波动。同样,在停泵时也会使电流和电压明显波动。由于这种原因,大多数操作人员都不愿意频繁地启-停电潜泵。这就产生了不同规格泵的设计问题。 Submersible pump due to the characteristics of its switch, so should not be used repeatedly (when open to stop). According to the normal method, the starting current is sometimes 5 to 8 times larger than the working current. Such fluctuations easily damage the motor and cables, but also cause line voltage fluctuations. Likewise, the current and voltage can fluctuate significantly when the pump is stopped. For this reason, most operators are reluctant to frequently activate - blackout pump. This creates a pump design problem of different specifications.
