The core of the robot is equipped with visual inspection and non-destructive thickness measurement function module, which can complete the comprehensive inspection of boiler water wall efficiently, safely, accurately and stably, and can quickly measure the wall thickness. identify the wall and burner soot blower and other visual defects, and by the matching control system for real-time display and intelligent analysis, compared with manual work, the comprehensive maintenance efficiency can be increased by more than 30%.
Taking the 600MW unit as an example, the width of the furnace is 19.4m, the height of the furnace is 67m, the height of the water wall is 50m, the number of tubes is about 600m, the diameter of pipes is 38, and the working area is about 3880 square meters. The detection efficiency of each operation module is as follows:
|Long working hours
|High pressure water cleaning
|3.2 million / min
|Suitable for furnace type of non-dry slag dredger
|Drum ash cleaning
|5.4 million / min
|Suitable for furnace type of dry slag dredger
|2.5 million / min
|It can work at the same time as bulging and thickness measurement.
|Non-destructive thickness measurement (single probe)
|The efficiency of multi-probe increases exponentially
|Non-destructive thickness measurement (3 probe)
|Non-destructive thickness measurement (5 probe)
|1.4 million / min
|Generally, only the wall tubes of key parts such as burners and soot blowers are detected.
