Common Fault Analysis and Optimization Suggestions for Design and Manufacturing of Impulse Turbine
According to the characteristics of hydropower resources in China,large-scale impulse hydropower stations will be an important direction for future hydropower development.At present,there are still many problems in design,manufacture and production operation.The authors summarize the common faults that have occurred in domestically produced impulse turbines,such as turbine vibration,cavitation and erosion of flow passing components,cracking of flow passing components,needle mechanism failure,intake ball valve failure,etc.The causes of the faults are analyzed,and the optimization suggestions of design and manufacturing are put forward,which can provide reference for the design,operation and maintenance of similar power stations.
