It has been widely used in the treatment of life sewage, urban sewage sludge, high viscosity liquid and even solid-liquid two-phase flow for its simple structure, long lifespan and simple maintenance. But in the manufacturing process, the gap between the rotor surface and the pump body is determined based on the designer ’s experience without specific data analysis. In this paper, based on the analysis of the linear mode shape of the arc-trileaf type cam rotor pump, the two dimensional model of the rotor pump is established. By using Fluent software, the distribution of flow field in the rotor pump with different gaps between the rotor su
