FINITE ELEMENT ANALYSIS ABOUT STATOR OF OPPOSED BICONINAL CONE SCREW HIGH-PRESSURE SEAWATER HYDRAULIC PUMP

Abstract

The rubber bush of the stator is not only the damageable parts of the opposed biconinal cone screw high pressure seawater hydraulic pump, and the combining status between the stator and rotor has a significant impact on the performance of the new type pump, so the related research on above problems are carried out. The contact finite element equation of the shell and bush is established and the deformation and stress of the stator's space and plane's model under the force state are compared and analyzed with the finite element method, and discuss whether the plane model could replace the space model on the finite element analysis of the deformation and stress about the stator. The analysis shows that the deformation and stress of the stator's plane model and space model have much difference, so the plane model can't replace the space model on the research of the finite element analysis.
