Compression circulating water-cooled submersible pump

Abstract

The embodiment of the invention provides a compression-type circulating water cooling submersible electric pump. The compression-type circulating water cooling submersible electric pump is composed of a pump body, a guide vane, an impeller, a water inlet (upper end cover), a bearing, an electromotor rotor, an outgoing cable, an outlet box, an electromotor stator, a lower end cover and a circulating water cooling guide pipe. Negative pressure is used as a circulating water cooling power source in a compression circulating water cooling mode, the integrated guide vane with a guide pipe is used for balancing the downward pressure of a water outlet of the submersible pump and the upward pressure of water subjected to centrifugation of the impeller, the opening of the guide pipe of the guide vane is downward, part of water pumped in by the submersible pump enters the circulating water cooling guide pipe in the pump body through the inlet of the guide pipe on the guide vane and downward reaches the bottom of the submersible pump, the water spirally flows to the electromotor stator and the electromotor rotor at the position, with the bearing, of the bottom at the angle of 45 degrees, then, the water evenly passes through the gap between the electromotor rotor and the electromotor stator in an even encirclement mode, and finally the water flows out with pipelines evenly distributed at the net-separated lower end of the water inlet as outlets. Therefore, heat of the submersible pump can be fast dissipated, and problems caused by over-high temperature are avoided.

Description

technical field [0001] The invention relates to a submersible electric pump, in particular to a compression type circulating water-cooled submersible electric pump. Background technique [0002] The submersible pumps commonly used in mines have poor heat dissipation. After a period of use, the stator windings in the motor will age and stick, causing short circuit damage to the motor. These problems have led to the current use of submersible pumps. The pump is repaired and replaced, resulting in a huge waste of manpower, material resources and other resources. Contents of the invention [0003] The embodiment of the present invention aims at the deficiencies of the existing submersible pumps, and proposes a compression-type circulating water-cooled submersible electric pump, including: [0004] The compression-type circulating water-cooled submersible pump consists of a pump body, guide vanes, impellers, water inlets, bearings, motor rotors, outlet cables, outlet boxes, mo...
