Furthermore, the machine barrel is fixedly connected with the end cover, and after the impeller assembly is installed, the impeller assembly is directly formed by fixing the end cover and the pump shell, so that the production steps are simple and the cost is low.

In the small water pump, the bottom of the pump shell is fixedly connected with the base, the side wall and the bottom surface of the base are provided with the plurality of filtering teeth, and the bottom surface of the base is of a spherical structure.

In the small water pump, the bottom of the pump shell is provided with a circle of arc-shaped groove, the base is provided with a circle of mounting step matched with the arc-shaped groove, and the base is fixed at the bottom of the pump shell through the matching of the mounting step and the arc-shaped groove.

In the small water pump, the end cover is internally provided with a control box, and the control box and the top of the motor are mutually supported and fixed.

In the small water pump, the top of the end cover is provided with a wire casing communicated with the control box.

In the small water pump, the end of the motor is fixed to the cylinder in a matching manner, and a sealing ring is arranged at the matching position.

Compared with the prior art, the submersible electric pump has the advantages that the motor and the impeller assembly are directly installed in the pump shell through the end cover, the motor runs stably with good heat dissipation performance, the assembly is convenient, and the manufacturing cost is low.
