多相混输泵是海洋油气资源开采的关键技术，必须努力保证其高效、稳定运行。提出了一种结合奇异性方法的多相混输泵可控速度矩设计方法，确定了无因次可控参数的取值范围。在IGVF（进口气体体积分数）= 0%时，优化泵I的压力升和效率比基准泵分别提高了11.9 kPa和3.6%，叶轮内压力脉动最大幅度降低了23.1%。在IGVF = 10%的工况下，优化泵II的压力升和效率比基准泵分别提高了7.6kPa和4.51%，叶轮平均压力脉动强度降低了47.53%。优化泵的优化机理是以最优速度矩分布抑制了转子与定子的相互作用和气液相互作用。
The multiphase pump is the key technology for offshore oil-gas resources exploitation, and great efforts should be made to guarantee its high-efficiency and stable operation. In the present work, a design method of controllable velocity moment in combination of singularity method is proposed for multiphase pump, and the ranges of dimensionless controllable parameters are determined. Under IGVF (inlet gas volume fraction) = 0%, the pressure rise and efficiency of optimization pump I increase by 11.9 kPa and 3.6% in comparison of baseline pump, respectively, and the maximum amplitude of pressure fluctuation in impeller decreases by 23.1%. Under IGVF = 10%, the pressure rise and efficiency of optimization pump II increase by 7.6 kPa and 4.51% in comparison of baseline pump, respectively, and the average pressure fluctuation intensity of impeller decreases by 47.53%. The optimization mechanism is that the rotor-stator interaction and gas-liquid interaction are suppressed in optimization pump with optimal velocity moment distribution.
