Abstract
The overall performance of the hydro turbine decreases with the increase in the erosive wear. Erosive wear of hydro power turbine components depends on various parameters such as silt concentration, silt size stream velocity and working time. In the current study, an experiment was carried out with Pelton turbine in actual flow conditions to investigate the outcome of silt size and silt concentration on the erosive wear of the Pelton turbine bucket. Examinations have been performed by the specimen of silt, gathered from Chamera Lake in Himachal Pradesh. The silt size varied from 90 to 450 , generally silt concentration fluctuated from 2000 to 8000 , stream velocity differed from 25.4 to 27.3 / and working time was 8 hours. In light of exploratory information, correlation has been produced as far as normalized wear (W) as a component of silt parameters and working parameters. Maximum erosion in Pelton bucket was observed on the splitter and some part of notch, and this result was a comparison with Finite Element Analysis simulation. Correlations for the erosive wear rate with operating parameters have been developed. The correlation established in this review can be utilized to anticipate the normalized wear with an error of ±12. 8%.
