Abstract
The aim of this paper is to predict the wear life of the parts of centrifugal pump for slurry transportation, used in a shield tunneling work, in order to set up the pump parts management and supply system. In this study, some factors affecting the wear of pump parts, including grain size distribution, quartz content, amendment roundness of slurry particles and the pump rotational speed, are considered. Based on the study about these factors, equations estimating the wear amount of frontliner and impeller are proposed. These estimation equations are also applied to anather case.
