Finite Element Analysis and Comparison of Screw Pump Models in Uniform Pressure

Abstract:

This paper establishes the two-dimensional model, three-dimensional simplified model and three-dimensional of the single-screw pump stators ,and accomplishes their displacement and stress analysis in even pressure inside the stator using ANSYS software. This paper analyzes the comparison results of the combined displacement, equivalent stress and shear stress cloud in the XY plane of single screw pump stator’s three different models. The results manifest the significant differences of the three models for finite element analysis. This study validates that finite element analysis of three-dimensional model leads closer to the true situation.
