Finite element analysis of wear for centrifugal slurry pump
By applying theory of liquid-solid two-phase flow, the location and process of wear on pump are analyzed. The results are consistent with the real wear situation. On this basic, base on the geometry non-linear theory and material non-linear theory, the wear process on flow components was simulated by ANSYS. The simulation results showed that there will be pits on the surface of flow components due to the impacting of coal particles with certain diameter, shape, impacting velocity and invasive angle; and the largest Von Mises stress will be at the pits. The distortion degree of pits and the largest Von Mises stress will increase with the increasing of coal particle diameter, impacting velocity and invasive angle, and with the decreasing of tip angle. There will be some accumulation at the front-end of impacting when the invasive angle is small.
