A Review of the Research on the Influence of Cavitation and Abrasion on Hydroturbine Performance

Large and medium sized water conservancy projects generally have comprehensive benefits such as flood control, water supply, irrigation and power generation. As the main hydraulic power generation equipment, the safe and economic operation of hydroturbine generator sets is of vital importance. For a hydroturbine affected by the flow of water in the running process, the paper explores the cavitation and abrasion phenomena, analyses the phenomenon of resource waste, energy waste and material waste caused by unreasonable protection of water turbine, and introduces relevant protective measures. These results further enhance the understanding of the corrosion resistance of the hydroturbine and could be used to optimize the hydroturbine protection techniques.
