Abstract

At a power station, the turbine experiences high sediment content and operates under complex and challenging conditions. It has been operating under unstable conditions for an extended period. The overflow components have suffered significant abrasion due to the combined effects of sediment abrasion and cavitation, posing a significant safety hazard and seriously compromising the safe and stable operation of the power station. This article discusses the technological updating of the overflow components at this power station, examines the causes of sediment abrasion and cavitation, and outlines the effective protective measures implemented during the technical, to provide valuable experience for future sediment abrasion resistance efforts at multi-sediment river power stations.
