Abstract

The invention discloses a shield electric motor for an oil-submerged pump and a preparation method therefor. The shield electric motor comprises a vacuum pump shell, a cable assembly, a stator assembly mounting cylinder sleeve arranged in the vacuum pump shell, a driving shaft, a rotor assembly mounted on the driving shaft, a stator assembly arranged in the stator assembly mounting cylinder sleeve, an upper end supporting base body assembly and a lower bearing base assembly, wherein the upper end supporting base body assembly and the lower bearing base assembly are arranged at the two ends of the stator assembly mounting cylinder sleeve, and a sealed cavity is formed in the stator assembly mounting cylinder sleeve; the rotor assembly is positioned in the sealed cavity; the stator assembly mounting cylinder sleeve comprises an inner cylinder sleeve, an outer cylinder sleeve, and a left end cover and a right end cover for fixing the inner cylinder sleeve and the outer cylinder sleeve together; the stator assembly in the stator assembly mounting cylinder sleeve is poured and sealed with epoxy resin; and the epoxy resin is poured and sealed through a resin pouring and sealing working table. The shield electric motor is simple in structure, high in insulation, high in safety, capable of eliminating an air-resisting phenomenon, long in service life, and convenient to process.

Description

technical field [0001] The invention relates to the field of shielded motors, in particular to a shielded motor for a submersible pump and a preparation method thereof. Background technique [0002] With the development of society, people's requirements for quietness, pollution and other environmental protection of gas stations are increasing day by day, especially for gas stations in downtown areas, medium and large gas stations and gas cities; now the gas dispenser with self-priming pump is commonly used in the market , Self-priming pumps are prone to less oil output (gas-liquid two-phase), environmental pollution, or even no oil output under high-temperature environments, high head, and long-distance conditions. [0003] The submersible pump uses the principle of positive pressure to push, fundamentally eliminates the air resistance phenomenon, and completely solves the problem that the self-priming pump cannot solve under the conditions of high temperature environment, h...
