To solve the problem of structural water shortage in remote mountainous areas in China, a new type of water lifting device based on the principle of gas-liquid energy conversion was developed. A multi-condition experimental study considering the three factors of head, intake pipe diameter and pump pipe diameter was carried out by adopting indoor model test. Through the analysis of the experimental data and observed phenomena, the relationship between the three influence factors and pump water efficiency is explored, which can provide the experimental basis for the selection of the system parameters in the practical engineering application.
