Submersible electric pump convenient to machine and assembly and high in assembly efficiency

Abstract

The invention relates to a submersible electric pump convenient to machine and assembly and high in assembly efficiency, and belongs to submersible electric pumps. The submersible electric pump includes a fastening bolt, a base, open retaining rings, bearing blocks, bearings, skeleton seals, a stator coil, rotor assemblies, a water inlet section, a rotor shaft, a water pump body, a casing and a water discharge bolt; the upper end of the casing is connected with the water pump body; the upper end and the lower end in the casing are connected with the open retaining rings; the open retaining ring at the lower end is connected with the base and the corresponding bearing block, the open retaining ring at the upper end is connected with the corresponding bearing seat and the water inlet section, and the stator coil is connected with the position, between the upper open retaining ring and the lower open retaining ring, in the casing; the bearings and the skeleton seals are connected to the upper and lower bearing blocks, and the rotor assemblies are connected to the two bearings; and the water discharge bolt is connected to the base. The submersible electric pump has the advantages thatit is ensured that the upper and lower bearing blocks are universal, the assembly precision requirements of the submersible electric pump are met, a water pump shaft and the rotor shaft are automatically locked and fixed, the labor intensity is reduced, the production efficiency is improved, the efficiency is high, and the assembly effect is good.

Description

technical field [0001] The invention relates to a submersible electric pump, in particular to a submersible electric pump which is easy to process and assemble and has high assembly efficiency. Background technique [0002] At present, the small submersible pumps and well submersible pumps produced by the company generally use cast iron parts to make the submersible pump casing, upper and lower bearing seats, and bearing end covers. Complicated, large machining allowance, bulky and difficult to process, and the upper and lower bearings are not universal, resulting in a low degree of generalization in assembly. [0003] When assembling the upper and lower bearing parts of a small submersible pump and connecting them with the casing, the combination assembly of the retaining ring plus the hole and the elastic washer is generally used, that is, the retaining ring is first placed inside the casing, and then the retaining ring and the upper and lower bearings are connected togeth...
