Fin-cooled motor for BCP pump

Abstract

The invention discloses a fin-cooled motor for a BCP pump. The fin-cooled motor comprises a stator, a rotor, and an outer cover, wherein a driving shaft is arranged at an inner shaft center of the rotor; the stator is arranged at the periphery of the rotor; a motor shell is arranged at the external of the stator; an air-conducting port communicated with the stator is formed on the motor shell; the inner wall of the air-conducting port is the high-temperature-resistant ceramic coating; and a rotary radiating frame is arranged between the motor shell and the outer cover. The fin-cooled motor for the BCP pump disclosed by the invention has the advantages as follows: (1) the rotary radiating frame and an air outlet are arranged so as to dispel the heat produced by the motor to the external of the motor, thereby effectively playing an aim of radiating by itself; (2) the rotary radiating frame is rotated by means of a driving shaft, thereby volatizing the heat and saving the power cost; and (3) the air-conducting port on the motor shell can radiate, and the inner wall of the air-conducting port is the high-temperature-resistant ceramic coating, and the service life of the air-conducting port is improved.

Description

technical field [0001] The invention relates to the field of boiler water circulation pumps, in particular to a self-radiating motor for a BCP pump. Background technique [0002] The BCP pump is the furnace water circulation pump, which is an important equipment for conveying high-temperature furnace water. When the circulation pump is working, the temperature of the high-temperature furnace water can reach above 370°C. Under such water temperature, if the motor in the furnace water circulation pump wants to work normally, it must do For better heat dissipation, heat exchangers are generally used or heat shields are installed between the pump body and the drive motor, but in order to ensure the normal operation of the motor, these two points cannot be fully achieved, and the motor is running at the same time, It will also generate a lot of heat. At this time, heat dissipation is particularly important. At the same time, the structure used for heat dissipation must also be re...

[0002] The BCP pump is the furnace water circulation pump, which is an important equipment for conveying high-temperature furnace water. When the circulation pump is working, the temperature of the high-temperature furnace water can reach above 370°C. Under such water temperature, if the motor in the furnace water circulation pump wants to work normally, it must do For better heat dissipation, heat exchangers are generally used or heat shields are installed between the pump body and the drive motor, but in order to ensure the normal operation of the motor, these two points cannot be fully achieved, and the motor is running at the same time, It will also generate a lot of heat. At this time, heat dissipation is particularly important. At the same time, the structure used for heat dissipation must also be resistant to high temperatures.
