Abstract
Description
Claims (2)
- 흡입되는 용수의 유량을 감지하는 유량 감지수단과,펌프의 내부와 외부를 연결하는 공기유통로를 개폐하는 전동 개폐수단과,상기 유량 감지수단을 통해 감지된 흡입 유량과 기 설정된 기준 흡입 유량을 비교하여 상기 펌프의 운전상태를 판단하여 구동을 제어하되 공운전이 판단되면 상기 펌프 내부의 공기 배출 신호를 출력하는 공운전 판단수단과,상기 공기 배출 신호에 따라 상기 전동 개폐수단을 통해 상기 공기유통로를 개방하여 상기 펌프의 내부 공기를 외부로 배출시킨 후 상기 공기유통로를 패쇄시키는 공기 배출수단을 포함하여 구성된 것을 특징으로 하는 펌프의 공운전 방지장치.
- 제 1 항에 있어서,상기 펌프 내의 수위를 검출하는 수위 검출수단을 더 포함하여 상기 전동 개폐수단은 검출된 펌프 내의 수위에 따라 상기 공기유통로를 패쇄시키는 것을 특징으로 하는 펌프의 공운전 방지장치.
