터보형 펌프의 내부조건 변화에 따른 성능실험 연구

The Performance-Experiment Study according to a Variation on an Inside Condition of Turbo Type Pump

For the improvement of turbo type pump, this study has been carried out a servies of experiments as a section-shape transformation of performance and discharge port and we made change the number such impeller blades in the case of variation on pressure and flow rate further the turbo type pump. The useful findings of the study is as follows. 1. In order to increase the flow rate of discharge, the cross section of discharge should be equal or greater than that of discharge circumscribed circle to the normal direction of circumference, and the flow friction can be reduced by making the cross sections of suction and discharge ro fuather shape. 2. 12 blades of pump wheel gets best efficiency in this pump. 3. For the most suitable efficiency proves to be 90o of exit angle to impellerexperiment of vane is recommenced.
