摘要:Self-priming pump [1] as the core equipment for flood fighting and emergency rescue, play an important role in flood prevention and other fields. Plenty of scholars pay a lot of attention on the performance improvement of selfpriming pump. Wu et al. [2] proposed five different blade profiles impellers to study the energy performance of selfpriming pump. Zhou et al. [3] investigated the influence of the reflux hole on the transient startup performance of the self-priming centrifugal pump. Yao et al. [4] employed the Fluent to analyse the gas-liquid two-phase unsteady characteristic of vertical self-priming pump, which could provide the reference to the design method of high-head vertical self-priming pump.
