Abstract

The study is designed to explore the failure condition of valve rubber. A numerical simulation of solid-liquid two-phase flow was carried out by using the Euler model and FLUENT. We examined the influence of solid concentration, punching, taper angle and lift on pump-rubber erosion. An increase in solid concentration and punching rises the velocity of the flow field through valve play and the erosion wear is much dangerous. With an increase in taper and lift angle of the pump valve, the speed of the flow field decreases in the valve play and the erosion wear is weakened. The numerical simulation results agree well with the experimental observations, which verifies the reliability of the calculation method for pump-valve rubber failure and provides a reasonable basis for structure optimization.
