Description

Technical Field

[0001] The utility model relates to a tool for cleaning the inner wall of an industrial cooler, in particular to a tool for cleaning the inner wall of an air-cooled high-voltage motor cooler. Background Art

[0002] When the air-cooled high-voltage motor is running, a large amount of natural air is sucked in from the center of the fan at the rear end of the motor, and flows away from the upper multi-channel cooler pipe, taking away a large amount of heat, ensuring that the motor winding temperature is within a reasonable range, and realizing long-term safe operation of the motor. Because the environment at the motor site contains various impurities, dust, etc., various impurities and dust are easy to adhere to the inner wall of the cooler pipe after long-term operation. In severe cases, the cooler pipe will be blocked, affecting the cooling effect of the cooler, causing the motor insulation temperature to rise, and even causing damage to the motor windings, resulting in serious accidents. The inner wall of the air-cooled high-voltage motor cooler needs to be regularly inspected and cleaned. For motors with a power greater than 300KW, the inner wall of the motor cooler is nearly 2 meters deep, and the internal space is narrow, which is not easy to clean. Utility Model Content
