Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flaw detection, in particular to a spraying device for penetrant flaw detection coloring liquid. Background Art
[0002] Currently, color flaw detection involves penetrating a colored dye into tiny cracks on a workpiece's surface. After cleaning, the dye is then coated with an adsorbent, allowing the colored oil within the flaw to penetrate the surface. The flaws are then detected and identified based on the colored spots and streaks. Due to its ease of use, color flaw detection has gained widespread application in industrial production.
[0003] The existing coloring liquid spraying device lacks an effective limiting mechanism during the spraying process of some metal bars. The surface of the metal bars is relatively smooth, which easily causes the metal bars to roll, resulting in uneven spraying of the coloring liquid and affecting the accuracy of the inspection results of the metal bars. Therefore, we propose a spraying device for coloring liquid for penetrant testing. Utility Model Content
