本专利技术是一种轴流、斜流式水轮机叶片控蚀装置,该装置能有效地防止转轮叶片背面气蚀作用,而且能有效地增强转轮叶片的耐泥沙磨损能力。结构特点是在转轮叶片的背面用螺栓和偏心套筒安装控蚀叶片,它是一个长方形,横截面为流线型,相对于转轮叶片的进口角和出口角能够调整,相对位置也能够移动。该装置供水力发电站、水利工程使用。
The patented technology is an axial flow, diagonal flow turbine blade erosion control device, which can effectively prevent the cavitation erosion on the back of the runner blade, and can effectively enhance the anti-sediment wear resistance of the runner blade. The structural feature is that the control erosion vane is installed on the back of the runner blade by means of a bolt and an eccentric sleeve. The utility model is a rectangle with a streamlined cross-section and can be adjusted relative to the inlet angle and the exit angle of the runner blade, and the relative position can also be moved. The device for hydroelectric power stations, water conservancy projects.
