Problems solved by technology

[0003] However, the existing submersible electric pumps are equipped with a rotating shaft at the center of the inner side, so it is inconvenient for the water to flow inside, which will affect the performance of the electric pump and reduce the performance of the electric pump. Affected, it is inconvenient to transport solid-liquid two-phase mixture

Abstract

The invention discloses a submersible electric pump. The submersible electric pump comprises a water inlet block, a water outlet block, a stator and a rotor, wherein a circular water inlet hole and acircular water outlet hole are formed in the water inlet block and the water outlet block separately; the stator comprises a stator core, a winding wire and a seat, the two ends of the seat are fixedly connected with the water inlet block and the water outlet block separately, and an accommodating interval is formed in the inner sidewall of the seat; the stator core is fixedly connected to the sidewall of the accommodating interval, and the winding wire is wound onto the stator core; and the rotor comprises a rotor core, a rotary barrel and an impeller, and the rotary barrel is rotationally connected into the accommodating interval. According to the submersible electric pump, a rotary shaft is not arranged at the inner side, flowing of water flow in the rotary barrel is facilitated, winding and blocking are not easily caused, the influence of a conveying medium is avoided, and a solid-liquid two-phase mixture containing impurities, sewage and the like is safely conveyed.

Description

technical field [0001] The invention relates to the technical field of electric pump equipment, in particular to a submersible electric pump. Background technique [0002] Submersible electric pump refers to a pump in which the pump body and the motor driving the impeller of the pump body are submerged in water, so it has a compact structure, light weight, and is easy to install, use and transfer. The motors used in existing submersible pumps include dry type, semi-dry type, oil-filled type and wet type. In order to ensure the heat dissipation and pressure bearing performance of the motor, deep well submersible pumps usually use wet motors, and their stator windings use water-resistant insulated wires. , water entering the motor has little effect, and the sealing structure can be greatly simplified. [0003] However, the existing submersible electric pumps are equipped with a rotating shaft at the center of the inner side, so it is inconvenient for the water to flow inside,...
