| 摘 要： | 对由矩形流道叶轮、复合式叶轮与大包角后弯叶轮组成的旋喷泵进行全流道数值模拟。研究发现，矩形流道叶轮的压力、速度分布都较均匀，泵的扬程、效率均能达到要求；后两种形式的叶轮的压力梯度分布不均匀，出口处压力分布不理想，速度分布也不均匀。速度分布的不均匀反映出内部流动的不平稳，有回流和大旋涡产生，效率很低。因此，旋喷泵的叶轮选择矩形流道的叶轮较好。

| Abstract: | Through comparing the three types of pumps with three different impellers: impeller with rectangle channel,compound impeller with short and long blade and impeller with warp angle blade,the authors draw conclusions: the distribution of the pressure and velocity in the rectangle flow channels is well-proportioned,the head and the efficiency of the hole pump can meet the requirement;But in other two types of impeller channels,the distribution of pressure's gradient is unstable,especially near the outlet,the u... |
