摘　　要：文为深入研究近年来在农业排灌应用中广受关注的气力提升泵的提升特性,本文基于Fluent软件,建立了不同进气角度下的三维物理模型,分析了不同进气角度、浸没比条件下气力提升泵的提升特性差异。结果表明:进气角度对气力提升泵液体流量、液体体积分数、径向速度及提升效率均有明显影响,最优进气角度为10°;高浸没比时,气相分布流型为明显搅拌流,优于低浸没比时的环状流。In order to deeply study the lifting characteristics of pneumatic lifting pumps which have received widespread attention in agricultural drainage and irrigation in recent years,three-dimensional physical models under different intake angles are established based on Fluent software,and the differences in lifting characteristics of pneumatic lifting pumps under different intake angles and immersion ratios are analyzed.The results show that the intake angle has a significant impact on the liquid flow rate,liquid volume fraction,radial velocity and lifting efficiency of the pneumatic lifting pump,and the optimal intake angle is 10°;the gas phase distribution flow pattern at high immersion ratio is obviously stirred flow,which is superior to the annular flow at low immersion ratio.
