Example Embodiment
[0021] Embodiment 1:
[0022] The submersible electric pump is composed of a casing 1, a stator 2, a three-phase winding 3, a winch 4, a water outlet flange 5, a base 6 and a suction hole 7. The casing 1 is welded with steel pipes or cast iron on both sides. A cylinder with flanges, the stator 2 is made of superimposed silicon steel sheets, the silicon steel sheets are punched into a ring shape, and the inner circle side is provided with a wire slot. The outer diameter of the blades of the winch 4 is consistent with the inner diameter of the stator 2. The outlet flange 5 is welded with a flange and a steel pipe. The three-phase coil 3 is embedded in the wire slot inside the stator 2. The stator 2 Installed in the housing 1, the winch 4 is installed in the cavity of the stator 2 and fixed on the base 6 with bolts. The winch 4 is made of non-conductive hard material ceramics, and the number of blades is 1.
