| Abstract: | Cavitation is a kind of greater destructive hydraulic phenomena, which is one of the common factors for threatening safe operation of hydraulic turbine. D568-F17 model turbine of Minzhi Hydropower Station was chosen to carry out energy test. According to the results of energy test, the appropriate conditions were selected for cavitation test. And then, it is predicted the cavitation characteristics of the prototype turbine based on the model test results of cavitation. The experimental results show that the highest efficiency, rated efficiency and weighted average efficiency of the prototype turbine all meet the requirements of related technology of hydropower station. Rated critical cavitation coefficient and incipient cavitation coefficient also meet the requirements of related technology of hydropower station. |
