Abstract:Side channel pump is a radial vane pump between positive displacement pumps and centrifugal pumps, and it entitles this name since the pump has a semicircular side channel around the impeller vanes. Usually the side channel pump is subject to a super low specific speed and has self-priming ability. Even though the pump has a small size and low flow rate, its head is quite high. Compared with centrifugal pumps, this new kind of pumps is better used to transport gas-liquid two phase fluids under extreme conditions and even nearly in the critical state. The components and working principle of side channel pump are introduced firstly, then the motions of fluid inside the pump is illustrated. Further, the current situation of study on side channel pumps is discussed according to time sequence, especially the work conducted abroad and in China is paid significant attention. Finally, the development trend of study on the side channel pump is prospected. The key issues in the study on side channel pumps include pump design optimization, theoretical head model development, investigation into internal flow pattern and vortex evolution mechanism in the pump by using advanced instrument such as PIV and LDA and new multifunctional products innovation.
