浸透深傷法は、表面欠陥の発見に非常に有効な方法であ
り、圧力容器等の健全性確認に不可欠な手段である。The penetrating deep wound method is a very effective method for discovering surface defects, and is an indispensable means for confirming the integrity of pressure vessels, etc.
従来、上記の浸透深傷法は全て手作業により行なわれ、
わずかに後乳化性浸透探傷法が自動化されているに過ぎ
ない。Traditionally, all of the above-mentioned deep penetration methods were performed manually.
Only a few post-emulsifying penetrant methods have been automated.
自動化を阻んでいる大きな要因は浸透液の除去にある。
すなわち．、不要浸透液の除去が不完全であれば、現像
時にこの不完全除去部も着色し、欠陥部のみの色別が困
難となり、また、浸透液の洗浄時間を長くすると、欠陥
部の浸透液も洗い流され、検出感度が低下する。従って
、浸透深傷法の殆んどが機械化されていない状況にあり
、例えば溶剤除去性浸透深傷法はその用途の広さにもか
かわらず、自動化が困難視されていた。ところで、原子
力プラント等被曝を伴なう装置を浸透探復する場合、作
業の遠隔自動化は是非とも必要とされるものである。A major factor hindering automation is the removal of the permeate.
In other words. If the removal of unnecessary penetrant is incomplete, this incompletely removed part will also be colored during development, making it difficult to distinguish the color of the defective part.In addition, if the cleaning time of the penetrant is prolonged, the penetrant in the defective part will be colored. is also washed away, reducing detection sensitivity. Therefore, most of the penetrating deep wound methods have not been mechanized, and for example, the solvent-removable penetrating deep wound method has been considered difficult to automate, despite its wide range of uses. By the way, remote automation of the work is absolutely necessary when penetrating and detecting equipment that involves exposure to radiation, such as a nuclear power plant.
本発明は、上記の諸点に鑑み、浸透探傷作業の自動化に
ついて種々研究中、開発されたものである。The present invention was developed in view of the above points during various studies on automation of penetrant flaw detection work.

より、余剰浸透液は完全に洗い流される。The air sent from the accumulator 11 is reduced to an appropriate pressure by the pressure reducing valve 9, and introduced into the cleaning liquid supply hydraulic tank 2 through the pressurizing hole 21 by the release of the pneumatic on-off valve 8. The cleaning liquid pressurized by this introduction of air flows through the conduit 2
6 and is sprayed onto the cleaning surface Q from the cleaning liquid spray nozzle when the on-off valve 3 is opened. On the other hand, the air from the accumulator 11 that is separated at the delivery point 14 is reduced to an appropriate pressure by the pressure reducing valve 13, and is supplied to the ejector 5 by opening the operating valve 12 to operate the ejector. . As a result of this operation of the ejector 5, the suction/slip 4, which is passed through the suction side, becomes a negative pressure, and the mixed liquid of the cleaning liquid and the penetrating liquid on the cleaning surface Q is sucked. The sucked mixed liquid is discharged together with air into the liquid recovery tank 7, which is transported to the exhaust side by the operation of the ejector 5. This air passes through the filter 6 to become clean air and is discharged outside the system, and the mixed liquid is stored in the waste liquid tank 16 via the drain valve 15. By performing the above operation 1 to 3 times, the excess permeate is completely washed away.
