Abstract

본 발명은 흡입공과 토출공을 갖고 U자형의 이송홈이 형성된 전방케이싱과 구동모터에 결합된 후방케이싱 사이에 상기 구동모터의 축에 결합된 임펠러가 내장되어 이루어지는 자흡식 펌프에 있어서, 상기 임펠러는 내륜과 외륜, 및 상기 내륜과 외륜 사이에서 상기 내륜을 중심으로 하여 방사상으로 연장되는 다수의 회전날개를 가지되, 상기 회전날개의 회전방향쪽 일측면에는 전방에서 후방쪽으로 소정 각도 경사진 경사면이 형성되고, 후단부에는 이웃하는 회전날개와의 사이에 생성된 개방공간을 일부 가로막는 가압판이 형성되는 것을 특징으로 한다. 본 발명에 따르면, 구조가 간단하면서도 유체에 대한 큰 가압력을 발생시켜 토출압, 토출량을 증대시킴과 함께 유체 흐름에 따른 마찰저항을 감소시킴으로써 펌핑효율을 향상시킬 수 있는 효과가 있다.
