Description

Aviation penetration detection four-wall embedded black light irradiation device Technical Field The application relates to the technical field of flaw detection, in particular to an aviation penetration detection four-wall embedded black light irradiation device. Background Penetration detection is a non-destructive detection method based on capillary action for detecting the discontinuity of openings in non-porous metallic or non-metallic materials to the surface. The principle is that a penetrating agent containing dye is applied to the surface of an object to be detected, if a discontinuity from an opening to the surface exists, the penetrating agent can enter the discontinuity under the action of capillary action, the superfluous penetrating agent on the surface is removed, and an imaging agent is applied, so that the penetrating agent in the discontinuity can be sucked out to form a display. In aviation repair, the application of penetration detection in civil aviation repair (overhaul, repair) is relatively wide, and in the field of overhaul of aircraft parts and aircraft structure, penetration detection is an effective method for detecting fatigue cracks. At present, in aviation penetration detection, a conventional suspended ceiling type or handheld type black light lamp is commonly used, if fluorescence penetration detection is adopted, the black light intensity for observing the water washing effect of the surface of a workpiece during water washing is generally not less than 300 mu W/cm, but the conventional suspended ceiling type or handheld type black light lamp is adopted at present.
