Abstract

Sand erosion is the system of unfaltering avoidance of the solid from the surface of the hydroturbine hardware which relies on the concentration, size, hardness of sand particles, stream speed, and properties of material of different parts of turbine and working hours of the turbine. It is one of the major and complex issues in Himalayan area particularly amid storm season. Various investigations on erosion of turbine have demonstrated that the material of turbine apparatus dissolved because of sand particles. This paper depicts the exhaustive examination of silt, disintegration of runner cutting edges, and guide vanes of 300 MW Chamera-II hydrocontrol plant. It has been observed that hardness, size, and shape are vital parameters concerning their impacts on disintegration of water-driven turbines. Ultimately, weight lessening of turbine and subsequent fall in the productivity of force plant because of residue disintegration was likewise investigated.
