Abstract

본 발명은 캔드 전동기 펌프의 유체순환 장치에 관한 것으로 특히 부하측 베어링과 샤프트 사이로 이물질이 쉽게 들어가지 않도록 하여 침적 현상을 감소시키며 캔 내부에 있는 유체 및 증기의 순환을 원활히 하여 건조운전으로 발생하는 마찰소음을 감소시킬 수 있는 것으로서 샤프트와 연결되는 임펠러 부싱의 중앙에 형성되어 체크볼이 빠지는 것을 방지하는 최대 크기의 내부순환홀과, 상기 내부순환홀과 같이 이물질이 포함된 유체 및 증기를 유출시키는 임펠러 부싱에 형성된 가이드 순환홀을 구비하였다.The present invention relates to a fluid circulation device of a canned electric motor pump, in particular, to reduce the deposition phenomenon by preventing foreign matter from entering between the bearing and the shaft on the load side, and friction noise generated by drying operation by smoothly circulating the fluid and steam in the can. The inner circulation hole of the maximum size is formed in the center of the impeller bushing connected to the shaft to prevent the check ball from falling out, and the impeller bushing for discharging fluid and vapor containing foreign substances such as the inner circulation hole. It was provided with a guide circulation hole formed in.
