Problems solved by technology

[0002] Some pump motors for wells are simply placed in water to dissipate heat, and some use the content disclosed in the prior application CN201821221539. The flow of water can be achieved by setting threads and impeller blades on the outer wall of the rotor. In actual use, it is found that the flow rate is slow and not ideal, and impurities such as sediment in the water are easy to enter the motor, causing internal wear; A high head requires a higher speed, but with the increase of the speed, the running stability of the motor in the water pump will decrease, which will affect the performance of the water pump. Therefore, how to effectively improve the stability of the motor during operation is particularly important; therefore, it is necessary to further improvement of

Abstract

The invention discloses a shielded water-cooled permanent magnet high-speed well pump motor, which has good cooling and heat dissipation effects, good operation stability and long service life. The key points of the technical scheme are a shielded water-cooled permanent magnet high-speed well pump The motor includes a casing, a stator, a rotor and a rotating shaft. The rotor is fixed on the rotating shaft. The two ends of the casing are respectively provided with an upper end cover and a lower end cover. The upper end cover is provided with an upper shaft hole adapted to the rotating shaft. There is a lower shaft hole adapted to the rotating shaft. The casing is an inner and outer double-layer structure. A shielding cavity is formed between the two layers of casings. The stator is installed in the shielding cavity, and the shielding cavity is filled with resin. The lower end of the rotor and the There is an axial thrust assembly between the lower end covers, the lower end of the shaft is also provided with a pumping impeller located outside the lower end cover, a guide channel is provided in the lower shaft hole, a water flow channel is provided outside the rotor, and a water passage is provided on the upper end cover. The water outlet, and the guide channel, the water flow channel and the water outlet are connected in sequence, and the invention is applicable to the technical field of motors.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a shielded water-cooled permanent magnet high-speed pump motor for wells. Background technique [0002] Some pump motors for wells are simply placed in water to dissipate heat, and some use the content disclosed in the prior application CN201821221539. The flow of water can be achieved by setting threads and impeller blades on the outer wall of the rotor.
