[0002] A submersible pump is a pump device specially used for water pumping and conveying in underground water, and is usually combined by an electric motor and a water pump and runs in water.

[0003] The existing submersible pump has a very wide application range and is commonly applied to farmland irrigation and drainage, water circulation of industrial and mining enterprises, urban water supply and drainage systems, sewage treatment and the like. Before starting the submersible pump, a key step is to ensure that the suction pipe and the inside of the pump body must be completely filled with liquid, and therefore the pump body needs to be buckled with an oil tank cover for sealing and isolating the rotor from the liquid. A plurality of fittings need to be installed on the oil tank cover, such as a hard oil seal, a submersible pump, an O-ring I, a skeleton oil seal and an O-ring II.

[0004] The press-fitting forming process of the core components (pump shell, stator and rotor) of the current submersible pump has optimization space. The existing production mode relies on multiple devices to complete different processes in stages, resulting in that the device cluster of the production line layout occupies a large area and has a high requirement for the space, and there is space redundancy in the collaborative operation between the devices, the overall space utilization is low, and the comprehensive cost is high, which needs to be improved.
