Abstract

Because of emission control of greenhouse gas, shipbuilders, especially those in Korea, are pushing forward to introduce eco-friendly ship-building technology utilizing LNG. However, Technical skills of domestic shipbuilders in manufacturing the cryogenic pump designed to supply LNG for vessels are so low that technical skills for design and manufacturing of core parts are in urgent need. Therefore, This study described about the Rotor as a core part of cryogenic submerged centrifugal pump for ship LNG supply system. We wish to utilize for the basic data to develop the technology for the Rotor as deducing the optimal outcome with the experimental and the analytical methods in material selection.

온실가스 배출규제에 따라 국내 조선소를 중심으로 LNG연료로 추진되는 친환경 선박기술 도입에 박차를 가하고 있는 실정이다. 그러나, 선박의 LNG 연료공급을 위한 극저온 펌프 (Cryogenic Pump) 제작의 국내 기술력은 매우 미흡한 현실로서 핵심 부품의 설계와 제작기술이 절실한 시점이다. 그리하여, 본 연구는 선박용 LNG 공급시스템용 극저온 잠액식 원심펌프의 핵심부품인 로터에 대하여 기술하고자 한다. 따라서, 재료선정을 위한 실험적 및 해석적 방법을 통한 최적결과를 도출하여 기술개발의 기초자료로 활용하고자 한다.
