Description
technical field [0001] The invention relates to the technical field of detecting the water-cooled wall of a boiler in a power station, in particular to an auxiliary device for measuring the thickness of a tube wall of a boiler water-cooled wall. Background technique [0002] With the continuous improvement of our country's national economy, large boilers, as a kind of heat exchange equipment, are more and more used in industrial production. For large boilers, the wall thickness reduction caused by the abrasion of water-cooled wall tubes has a great impact on the safe and stable operation of the boiler, and is also the key content of boiler anti-wear and explosion-proof management; Ultrasonic detectors are used to complete the work, and there is a problem that the workload is large and the quality of detection fluctuates greatly with the skill level and work attitude of the personnel. [0003] In addition, in the actual production process, there will be dust attached to the ...
