Description

Technical Field

[0002] Electric motors are widely used in the industrial field, and have advantages such as good controllability, low cost, and long life. Many devices are powered by electric motors. Electric motors generate heat during work. Small electric motors are air-cooled, while large electric motors have poor fan cooling effect. When the motor has a large load, the motor body heats up quickly, and the continuous high temperature of the motor affects the life of the motor. Large electric motors generally add coolers to reduce the wind temperature to cool the motor, and use circulating water to take away the heat through the cooler. In the actual production process, the circulating water contains impurities, and long-term work causes the cooler to be blocked, affecting the cooling effect and reducing the service life of the motor. At present, the cleaning of the cooler is done manually; the staff holds a long brush and pokes it into each cooling channel of the cooler, and injects high-pressure water into it for flushing; the cooler has a lot of cooling channels, and the process of staff cleaning one by one is extremely inefficient and labor-intensive; therefore, a device that can efficiently clean the cooler is needed, thereby reducing the labor intensity of the staff and improving the cleaning efficiency.
