针对石油化工行业多数离心泵处于非设计工况下工作的现状，提出了通过改变叶轮外径和叶片包角重新设计叶轮的方法来提高离心泵的效率，并用 Fluent 软件对叶轮内部流场进行模拟分析，得到了叶轮流场速度和压力由吸入口到排出口逐渐增加，分布均匀，没有突变的规律。

In petrochemical industry,most of the centrifugal pumps work in non-design conditions.A method of changing the impeller diameter and wrap angle was proposed in order to improve the efficiency of centrifugal pumps.Then impeller flow field was analyzed using Fluent.It was found that the distribution of impeller field speed and pressure was gradually increased and no mutations occurred from the suction port to the outlet.
