Abstract
At present solid-liquid two-phase flow pump faces two big problems: the low efficiency, the short life, then the concentration of the conveyed solid-phase media are the important factors which affect the outside characteristics about this two phase flow pump. This article presents the outside characteristics' experimental research and internal flow field's simulation analysis on AH type slurry pump which is product by Shijiazhuang Shi- Jiang pump industry, discusses the flow rule in the impeller, and summaries the influence of the solid phased particles' concentration on the performance of the slurry pump's outside characteristics. At last, the rationality and accuracy of the numerical calculation method are verified through the way of comparing numerical simulation with experimental results in this two phase flow pump. And the relation between slurry pump's outside characteristics and granule concentration is summarized, which provided theoretical guidance for the slurry pump's optimization design and selection.
