本文研究固液、气液、气液固多相流对离心泵性能的影响。通过对泵输送这些流体时扬程、效率、功率和汽蚀性能变化的试验结果分析，探索固相、气相对离心泵性能的各别影响和作用机理，有助于离心泵内多相流的深入研究。研究表明固相对离心泵性能的影响是连续的、均匀的，与其浓度相关；气相对离心泵性能影响较大并与含气量及液相流量有关；三相流时的情况更复杂，受气、固相联合作用的影响。
This paper studies the solid-liquid, gas-liquid, gas-liquid multiphase flow on the performance of centrifugal pumps. Based on the analysis of the experimental results of the lift, efficiency, power and cavitation performance of the pump when transporting these fluids, the influence of the solid phase and the gas phase on the performance of the centrifugal pump is explored, which is helpful to the multiphase flow in the centrifugal pump the study. The results show that the influence of solid phase on the performance of centrifugal pump is continuous and uniform, which is related to its concentration. The influence of gas phase on the performance of centrifugal pump is relatively large and related to gas content and liquid phase flow rate. When the three-phase flow is more complicated, Effect of solid phase interaction.
