Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pumps, in particular to a pipeline pump motor with a cooling structure. Background Art

[0002] A pipeline pump is a device specially designed to transport and pressurize liquids in a pipeline system. It is usually installed at a specific location in the pipeline to provide the necessary pressure to lift or transfer liquids, ensuring that the liquid can flow smoothly in the pipeline network.

[0003] The pipeline pump can drive the impeller to rotate through the motor, thereby generating centrifugal force, sucking in the liquid and discharging it after pressurization. During this process, the pipeline pump can maintain a stable flow and pressure output. The traditional pipeline pump motor will generate a lot of heat during operation. If the heat is not dissipated in time, the motor temperature will rise, which will affect the performance and life of the motor. Generally, it is mainly achieved by heat dissipation on the surface of the motor housing and auxiliary heat dissipation by an external fan. For example, the Chinese utility model patent disclosed by publication number CN217873289U: A heat-dissipating vertical pipeline pump, the application includes a pipeline pump body, the outer side wall of the pipeline pump body is symmetrically provided with a first groove and two second grooves, the interior of the first groove is elastic and slidingly matched with a sliding plate, the interior of the second groove is elastic and slidingly matched with a sliding plate There is a bevel block, and a slide groove is opened on one side of the bevel block. There are two T-shaped blocks on the pipeline pump body that are symmetrical, elastic and slidingly matched. The heat dissipation cover is provided to facilitate the heat dissipation of the pipeline pump body to the inside through the heat dissipation cover, reducing the situation where the internal temperature of the pipeline pump body is too high and damaged. The bevel block is provided to enable the bevel block to slide in and out of the slot under the drive of the T-shaped block, so that the T-shaped block can position and release the positioning column through the slot, making the process of removing impurities with the heat dissipation cover more convenient. Therefore, this application still uses natural cooling to cool the motor. Therefore, this cooling method cannot effectively and quickly remove the heat of the motor when the motor is running at full load. At the same time, the overall volume and weight of the motor used in this application are large, which is not conducive to the transportation and installation of the pipeline pump.
