摘　　要：为提高混凝土泵的吸料性能,提高泵送效率,采用数值模拟的方法研究料斗内搅拌叶片的个数和形状对吸料性能的影响,并进行试验验证。选用的搅拌叶片形式分别为3片式叶片不开孔、2片式不开孔和2片式开孔等3种,研究结果发现增加叶片个数能够加强搅拌作用,提高料斗内混凝土的流动速度,进而提升吸料性能,但叶片是否开孔对吸料性能影响不大。In order to improve suction performance and pumping efficiency of concrete pump,numerical simulation method is used to study the influence of number and shape of mixing blades in the hopper on suction performance,and it is verified by tests.The three types of selected mixing blades include 3-piece blades without holes,2-piece blades without holes and 2-piece blades with holes.The research results show that increasing the number of blades can enhance mixing effect,improve flow speed of concrete in the hopper,and then improve suction performance,while whether the blades are with or without holes has little effect on the suction performance.
