Improvement of Pump Performance and Suppression of Cavitation in a Centrifugal Pump by J-Groove
Access this Article
The purpose of the present study is not only to develop a simple method to improve pump performance but also to suppress the occurrence of cavitation in the centrifugal pump by use of J-Groove. J-Groove is a shallow groove installed on the casing wall in the meridional direction. The application of J-Groove to a centrifugal pump with a new type impeller of "semi-closed impeller" has proved its effectiveness as a useful countermeasure of the unstable pump performance and cavitation. The results show that the combination of semi-closed impeller and J-Groove is applied successfully and improves both the pump performance and suction performance.
