Abstract
The aim of this study is to develop a methodology to estimate the wear between rotor and stator of the screw pump, under static and transient conditions, respectively, by using a two- dimensional finite element model. Because the velocity and the contact pressure were varied at the point of contact, it made the problem nonlinear and complicated, as the plane motion of the rotor in the stator. A geometry analysis, which incorporated a finite element method is developed to solve the problem. The variation of wear with frequency, friction coefficient and also with interference is presented and discussed.
