Summary:The invention discloses a water pump type selection method of a large-scale pump station low-lift pump device. The invention belongs to the technical field of hydraulic engineering and fluid mechanical engineering. The model selection method is scientific and has a clear principle, the flow Q0 and the lift H are designed through a known pump station; the flow Q of a single water pump is solved byselecting the number Z of units of 2-3 schemes; aDJUSTING ND VALUES, the specific speed similar to that of an excellent pump device is obtained; the most critical water pump nD value and the specificrevolution of the pump device are designed to establish a quantitative relation through the pump device model test database, so that the water pump model selection process is stylized, the optimal model selection of the water pump device is quickly realized, the model selection efficiency is improved, and the model selection quality is improved. 一种大型泵站低扬程泵装置的水泵选型方法，属于水利工程和流体机械工程技术领域，本发明选型方法科学，原理清晰，通过已知泵站设计流量Q、扬程H，通过选取2～3个方
