극저온용 2단 임펠러 액중펌프 역설계에 관한 연구

Abstract

This study represents basic research for the development of submerged pump technology applicable totransfer and storage of a cryogenic liquids. Its purpose is to secure baseline design data by applying reverseengineering to the process of developing a submerged cryogenic pump. The two-stage model included in theARTICK Series LNG Submerged Pump produced by Vanzetti of Italy was selected for analysis fordevelopment of a localized product, and was disassembled for reverse engineering. The pump wasdisassembled after analyzing its processing/assembly characteristics such as shrinkage of fittings. In addition,the materials used in manufacturing of the main components were analyzed, and the ingredients wereconfirmed. As a result, a design drawing for each component required for product development was securedvia foundational design, and a test product was manufactured by maximizing the application of appropriatedomestic technologies.
