The study proposes a design method for multiphase pump that optimizes pressure rise and efficiency through controllable velocity moment under different inlet gas volume fractions, reducing pressure fluctuations in the impeller.
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.
