Abstract

In this study, a blasting nozzle was designed based on incompressible flow analysis to clean wide surface of parts used in power plant. The outlet side section of the designed nozzle has a wide bore with a linear shape. After the design, the nozzle prototype was made by three dimensional printing, and the cleaning performance test was performed after mounting it on the blasting machine. The wide bore size obtained after the analysis was almost the same as the wide bore size obtained from the surface of the plate specimen after the experiment. Ultimately, it was confirmed that the design of blasting nozzle for wide surface treatment is effective.

본 연구에서는 발전소에서 사용되는 부품의 넓은 표면을 세정하기 위한 브라스팅 노즐을 비압축성 유동해석에 기초하여 설계하였다. 설계된 노즐의 출구측 단면은 광폭의 직선 모양이다. 설계 후 3차원 프린팅으로 노즐 시제품을 제작하였고 이를 브라스팅 머신에 장착 후 세정 성능실험을 수행하였다. 해석 후 얻은 광폭 크기와 실험 후 시편 표면에서 얻은 세정된 광폭 크기가 거의 같았다. 이로부터 대면적 표면처리를 위한 브라스팅 노즐의 설계가 유효함을 확인하였다.
