Example Embodiment

[0021] Embodiment 1:

[0022] The submersible electric pump is composed of a casing 1, a stator 2, a three-phase winding 3, a winch 4, a water outlet flange 5, a base 6 and a suction hole 7. The casing 1 is welded with steel pipes or cast iron on both sides. A cylinder with flanges, the stator 2 is made of superimposed silicon steel sheets, the silicon steel sheets are punched into a ring shape, and the inner circle side is provided with a wire slot. The outer diameter of the blades of the winch 4 is consistent with the inner diameter of the stator 2. The outlet flange 5 is welded with a flange and a steel pipe. The three-phase coil 3 is embedded in the wire slot inside the stator 2. The stator 2 Installed in the housing 1, the winch 4 is installed in the cavity of the stator 2 and fixed on the base 6 with bolts. The winch 4 is made of non-conductive hard material ceramics, and the number of blades is 1.

Abstract

An integral electric submersible pump belongs to the technical field of general equipment. Particularly, a cavity of a stator is used as a pump body, and the electric submersible pump is an integral structure. Rotating components including a motor rotor, a coupler, a pump shaft, an impeller, a bearing and the like are not arranged on the integral electric submersible pump. The integral electric submersible pump is characterized by consisting of a shell 1, a stator 2, a three-phase winding 3, a reel 4, a water outlet flange 5, a base 6 and a suction hole 7. Compared with a traditional submersible pump, the integral electric submersible pump has the advantages that the pump body and a motor are integrated, and the integral electric submersible pump does not have the rotating components, is simple in structure and low in fault rate and repair workload, and can be widely used for various industries using electric submersible pumps in the fields of the agriculture and the industry.

Description

technical field [0001] The invention relates to an integrated submersible electric pump, which belongs to the technical field of general equipment, and specifically relates to a submersible electric pump which uses the hollow body of the stator as the pump body to make it an integrated structure. It itself has no motor rotor, coupling, The pump shaft, impeller and bearing can be widely used in the field of industrial and agricultural submersible electric pumps, and has the advantages of simple structure, reliable operation and low failure rate. Background technique [0002] In industrial and agricultural production, submersible pumps are one of the most commonly used general-purpose equipment. Most of the submersible pumps are centrifugal pumps, and the installation form is usually vertical installation. [0003] The structure of a traditional submersible pump: [0004] Submersible pumps are usually composed of motors, pump casings, pump shafts, impellers and bearings. The ...
