Abstract:
A flux distribution measuring apparatus measures distribution of flow rates of a flowable medium. The measuring apparatus includes thin metal wire(s) for scanning a flowable medium and lead wires connected to the thin metal wire(s), wherein a voltage difference is detected between adjacent lead wires while the measuring apparatus scans the flowable medium in the direction perpendicular to a flow path of the flowable medium. The voltage differences are generated due to temperature changes in the thin metal wire(s) while scanning the flowable medium having different flow rates. The measuring apparatus visualizes the distribution of flow rates of a flowable medium using a computer which receives and processes the voltage differences detected.

본 발명에 따르면, 본 발명에서 가장 도전적인 이슈는 보수 엔지니어가 그들의 현재의 성능시험 테스트 결과에 기초하여 진공펌프의 교체를 위한 적절한 시간의 판단을 가능하게 하는 시스템적 방법을 찾는 것이였다. 게다가, 현재 얻어진 진단분석 결과와 초기(또는 표준) 데이터 집합을 비교하는 것은 보수 엔지니어가 도출된 펌프 성능 지표에 따라 대상 진공펌프의 교체여부를 결정하는 것을 가능하게 하는 것으로 보여진다. 또한, 현재 진공펌프의 도출된 펌핑 속도 지표는 대체로 감소하는 것으로 보고된다. 이러한 양적 진단 분석 결과는 그들의 현재 성능 수행 결과에 기초하여 진공펌프의 교체를 위한 적절한 시간을 판단하는 것을 가능하게 할 뿐만 아니라, 저 진공펌프의 예보유지의 안정성 및 신뢰성 또한 개선시킬 것으로 예상된다.
