Abstract

본 발명은 펌프에 관한 것으로, 종래의 펌프는 사용용도에 따라 즉, 깊은 우물용인 경우에는 웨스코타입의 펌프를 사용하였고, 이송용으로는 원심 타입의 펌프를 사용하였는 바, 각각의 경우에서 상대적으로 양정이 클 때는 유량이 작은 것이 문제였고, 유량이 크면 양정이 작아지게 되어 적절한 펌프의 사용에 어려움이 있었는 바, 웨스코 타입깃(14)과 원심 타입깃(15)이 형성되어 있는 임펠러(16)와, 유체를 상기 웨스코 타임깃(14)으로 유도하는 1차흡입구(17)와, 유체를 상기 원심 타입깃(15)으로 유도하는 2차흡입구(18)와, 상기 1,2차흡입구(17)(18)를 선택적으로 개폐하는 플로팅볼(19)을 포함하여 구성한 본 발명을 제공하여 중량 원심타입 펌프와 웨스코타입 펌프의 장점을 살리는 임펠러와 유로전환구조를 실시하여 펌프 가동시에는 양정을 높여 주고, 펌프의 정상상태 진입 후에는 유량을 높이도록 함으로써 보다 효과적인 펌핑작업을 실현하도록 한 것이다.The present invention relates to a pump. According to the conventional pump, a wesco type pump is used in case of a deep well, and a centrifugal pump is used for transfer. The problem was that the flow rate was small when the head was large, and the head was small when the flow rate was large. Therefore, it was difficult to use an appropriate pump. The impeller 16 having the wesco type feather 14 and the centrifugal type feather 15 was formed. And a primary suction port 17 for guiding fluid to the wesco timepiece 14, a secondary suction port 18 for guiding fluid to the centrifugal type feather 15, and the primary and secondary suction ports 17. Provides the present invention comprising a floating ball 19 to selectively open and close the (18) to implement an impeller and flow path switching structure to take advantage of the centrifugal pump and Wesco type pump to raise the head at the time of pump operation Give, pump After entering the steady state of to increase the flow rate to achieve a more effective pumping operation.
