“…The efect of softness on the erosion resistance of rubber elastomers has also been the subject of previous studies. In a study by Zuev et al [36], the efect of slurry temperature on the erosion rate of rubber elastomers was studied. It was found that the erosion rate decreased when the temperature was increased from 20 to 70°C.…”

“…First, a chemical reaction may take place between the lowing luid and the elastomer surface. For example, it was shown by Zuev et al [36] that the erosion resistance of rubber is a function of the resistance of the elastomer to chemical reaction with the aggressive media. It was shown that as the concertation of acetic acid increased in the abrasive medium, the wear rate increased.…”

“…Accordingly, in some previous studies, testing assemblies capable of erosion testing at controlled temperatures by employing an external heat source has been developed. Zuev et al [36] conducted erosion testing at elevated temperatures by controlling the slurry temperature. The increase of slurry temperature from 20 to 70°C improved the erosion resistance of the rubber owing to the improvement in elasticity and softness of rubber at the elevated temperature of 70°C.…”

Material removal caused by the impact and sliding of a stream of particles is a typical wear mode in the oil and gas industry. Protective coatings can be employed to increase the service life of equipment that is exposed to harsh erosive and abrasive environments. Among all the types of protective coatings and liners, polyurethane elastomers have received great atention owing to their excellent wear resistance and comparatively low cost that would allow for large-scale applications. The excellent wear resistance of polyurethane elastomers is a result of their high resilience and propensity to elastic deformation that enables the absorption of impact energy of erodant particles with minimal damage. The relation between the wear resistance of polyurethane and its mechanical properties has been the subject of previous studies. This chapter reviews the research that has been conducted to study the wear resistance of polyurethane elastomers. Testing apparatuses employed, material characterization techniques, evaluations of material removal mechanisms, and parameters with the strongest efect on wear resistance of polyurethane elastomers are herein explored. A review of inite element modelling approaches for in-depth study of the wear phenomenon of polyurethane elastomers is also presented in this chapter.

“…Arnold and Hutchings (1992) studied the erosion wear mechanism of elastic materials and found that erosion wear rate is related to the impact velocity, impact angle, particle size, elastic modulus and fatigue properties of the elements. Zuev and Chelmodeev (1968) discussed the effects of temperature and other factors on the erosion wear of rubber. Zhang and Wang (1993) and others had proposed four kinds of rubber materialabrasive erosion of physical models and physical processes.…”

The study is designed to explore the failure condition of valve rubber. A numerical simulation of solidliquid 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.
