Summary:The present invention relates to an integrated multi-stage inducer in which a plurality of blades having different sizes are formed in a multi-stage integrated shape. According to the integrated multi-stage inducer of the present invention, which includes blades extended from one side to the other side of a shaft, the blades comprise a front end portion formed on the front side, a rear end portion formed on the rear side of the front end portion and having a greater radius than the trailing end of the front end portion, and a transition portion whose radius and thickness continuously change between the trailing end of the front end portion and the leading end of the rear end portion. The front end portion, the rear end portion, and the transition portion are integrally formed. Therefore, the present invention prevents the overall length of a shaft from being extended while adopting a small-diameter auxiliary inducer to improve the suction performance of a pump, thereby preventing an increase in the weight of a system and improving the dynamic stability of the shaft system. 본 발명은 크기가 다른 복수의 날개가 다단의 일체형으로 형성된 일체형 다단 인듀서에 관한 것으로, 본 발명의 일체형 다단 인듀서는 축의 일측에서 타측으로 연장 형성되는 날개를 포함하는 인듀서에 있어서, 날개가 전측에 형성되는 전단부, 상기 전단부의 후측에 형성되며, 상기 전단부의 끝단 보다 큰 반경을 갖는 후단부, 및 상기 전단부의 끝단에서 후단부 시작단 사이에서 반경과 두께가 연속적으로 변화하는 천이부가 일체로 형성되어, 펌프의 흡입성능을 향상시키기 위해 직경이 작은 보조 인듀서를 채용하면서도, 전체적인 축 길이가 연장되는 것을 방지하여, 시스템의 무게가 증가하는 것을 막을 수 있고, 축계 동력학적 안정성을 향상시킬 수 있다.
