Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, a submersible motor with efficient cooling and self-cleaning functions according to the embodiment of the present invention includes a stator 15 , a rotor 16 , a casing 14 , a water jacket 8 , a cooler and an impeller 5 . The stator 15 is fixedly connected in the cavity of the casing 14 . The rotor 16 is connected to the casing 14 through bearings and bearing seats. The stator 15 is adapted to the rotor 16 . A waterway is provided in the casing 14 . The water jacket 8 is fixedly connected to the outer surface of the casing 14 . The cooler is fixedly connected with the casing 14 . The impeller 5 is fixedly connected to one end of the rotor 16 . The water jacket 8, the water channel communicate with the cooler to form a loop.

[0020] After the motor heats up, the temperature of the winding rises, which...

Abstract

The invention discloses a submersible motor with functions of efficient cooling and self-cleaning. The submersible motor comprises a stator, a rotor, a housing, a water jacket, a cooler and an impeller and is characterized in that the stator is fixedly connected into the inner cavity of the housing, the rotor is connected to the housing through a bearing and a bearing block, the stator is matchedwith the rotor, a water channel is arranged in the housing, and the water jacket is fixedly connected to the outer surface of the housing; the cooler is fixedly connected with the housing; the impeller is fixedly connected to one end of the rotor; the water jacket and the water channel are communicated with the cooler to form a loop. The submersible motor has the advantages that the radiating of the motor can be accelerated, the operation temperature of the motor can be lowered, steel scraps and rust inside an electric pump can be cleaned, the damage probability of a motor coil can be reduced,and the working time and service life of the motor can be prolonged.

Description

technical field [0001] The invention relates to a submersible motor, in particular to a submersible motor with efficient cooling and self-cleaning functions. technical background [0002] In the prior art, the submersible motor is only filled with clean water inside the motor for cooling. Motors generate heat when they are running. At this time, the clean water charged inside the motor absorbs the heat emitted by the motor and generates a temperature difference to form convection. However, due to the flow formed by convection, the water flow is slow, and the heat of the motor cannot be dissipated in time, which may easily cause the motor winding to overheat, thereby causing damage to the motor. At the same time, because the motor has been immersed in water for a long time, most of the parts are steel parts, and there are rotating friction parts, more or less rust residue, iron filings, etc. will be produced inside the long-term operation. These impurities can damage the w...
