Abstract

We aimed to develop a non-clogging submersible slurry pump with two blades to replace the conventional vortex pump. To do this, we simulated the effect of parameters such as the blade angle $\beta$ and the blade-length angle $\alpha$ on pump efficiency. We used the commercial codes ANSYS CFX and BladeGen. The results showed that the best blade shape was obtained for $\beta$ = $30^{\circ}$ and that the pump efficiency was proportional to $\alpha$ in the simulated range.

본 연구는 볼텍스 형태를 대신하는 원심형태의 비 막힘형 2엽 수중 슬러리 펌프 임펠러를 개발하기 위해 수행하였다. 이를 위해 먼저 펌프 설계에 있어 중요한 변수로 입구면 날개각(blade angle)과 날개 길이 각(blade length angle) $\alpha$를 선정하여 이들이 펌프의 효율에 미치는 영향을 살펴보기 위해 상용 코드인 ANSYS CFX and BladeGen을 사용하여 해석을 수행하였다. 그 결과 입구면 임펠러 날개 형상은 $\beta$값이 $30^{\circ}$ 로 일정한 값을 가질 때 가장 높은 효율을 가지게 됨을 알 수 있었으며, $\alpha$값은 효율에 비례하는 특징을 가짐을 관찰할 수 있었다.
