Cooling device of large-scale motor

Abstract

The invention discloses a cooling device of a large-scale motor. The cooling device comprises an evaporator heat pipe set, a condenser heat pipe set and temperature sensors, wherein the upper end of the evaporator heat pipe set is communicated with an evaporator air collecting pipe, the lower end of the evaporator heat pipe set is communicated with an evaporator liquid separating pipe, the upper end of the condenser heat pipe set is communicated with a condenser air separating pipe, the lower end of the condenser heat pipe set is communicated with a condenser liquid collecting pipe, a condenser fan is arranged at the back side of the condenser liquid collecting pipe, the evaporator air collecting pipe is communicated with the condenser air separating pipe through an air pipe connecting pipe, the evaporator liquid separating pipe is communicated with the condenser liquid collecting pipe through a liquid pipe connecting pipe, the temperature sensors are installed on the evaporator air collecting pipe and the condenser liquid collecting pipe respectively, and the temperature sensors and the condenser fan are respectively connected with a controller. The cooling device can lower the temperature of circulating air entering the motor, can improve efficiency of heat exchange between the air and a motor winding, and obviously cools the motor.

Description

technical field [0001] The invention relates to motor equipment maintenance technology, and more specifically relates to a large-scale motor cooling device. Background technique [0002] In modern industrial production, especially in metallurgical enterprises, large motors are an indispensable equipment, which plays a very important role in the production of strip steel products, fluid transportation, and in ensuring product quality and safe production. This type of motor mostly adopts its own fan, which cools the motor with the operation of the motor, and is installed in different locations according to different uses. In large-scale metallurgical industries, this type of motor is mostly installed in basements or places where the temperature is harsh. , these areas are difficult to be equipped with air conditioning devices, and there are a lot of heating equipment, but with the acceleration of production rhythm and the increase of service life, the performance index of the ...

This type of motor mostly adopts its own fan, which cools the motor with the operation of the motor, and is installed in different locations according to different uses. In large-scale metallurgical industries, this type of motor is mostly installed in basements or places where the temperature is harsh. , these areas are difficult to be equipped with air conditioning devices, and there are a lot of heating equipment, but with the acceleration of production rhythm and the increase of service life, the performance index of the motor is declining year by year, which is manifested in the temperature rise of the motor winding due to aging, resulting in motor failure The heat generation is greatly increased, and such large motors are often installed in a small space, which is difficult to solve directly through ventilation. In order to ensure the safe production of the motor, a simple and practical, high control performance, reliable operation, and low failure rate are sought for large-scale motor cooling. Devices are the goal pursued by maintainers in this field
