Abstract
In this paper,in order to simulate the clearance change caused by the wear of three screw pump during operation,a finite element model of three screw pump flow field with clearance change was established,and the independence of flow field grid was verified.The flow field was simulated by Fluent software,and the dynamic simulation analysis of three screw pump under different clearances was realized,and the distribution results of fluid pressure field and velocity vector in the pump under different clearances were obtained.The results show that different types of clearances have different influence intervals on the pressure distribution of the flow field.Different types of clearances have different regions where leakage and backflow occur.Among them,the clearance between teeth has the most obvious pressure drop effect on the flow field,and the normal clearance has the most obvious effect on the outlet flow of the flow field.关键词
