  • Vol. 21 - Issue 2, 2014

A major challenge for maintaining hydro plants on silt-laden rivers is the effect on machinery of large quantities of sediment with hard abrasive mineral fragments. This article discusses some case studies in Nepal, including the effects of the assembly design of components on the maintenance of Francis turbines. Some new concepts are discussed which are aimed at optimizing the assembly design, and thus minimizing the outage time during maintenance.
