Claims (3)
- 나선형식의 날개를 지니며 펌프 상류측에 일체로 설치되는 인듀서에 있어서:날개 끝단의 와동에 의한 영향을 줄이기 위해 입구에서 회전방향으로 전향하는 스윕(S)을 지니며, 발생한 기포를 내부에서 터뜨리기 위해 충분한 압력 상승을 갖도록 확대시킨 통로(P)를 구비하는 것을 특징으로 하는 공동현상 제거 구조의 펌프 인듀서.
- 제 1 항에 있어서,상기 인듀서의 스윕(S)은 스윕각(θ)(θ0)이 허브(Rhub)에서 끝단(Rtip)까지의 관계식으로 변화하는 것을 특징으로 하는 공동현상 제거 구조의 펌프 인듀서.
- 제 1 항에 있어서,상기 인듀서의 통로(P)는 정해진 길이 L, 입구각일 때 축방향 변화량 Z가 θ의 함수의 관계식에 의해 그 유로단면적이 점진적으로 증가되는 것을 특징으로 하는 공동현상 제거 구조의 펌프 인듀서.
