摘要： A runner for a hydraulic turbine or pump, comprising a plurality of blades (2, 22), each blade (2, 22) being defined by a pressure surface an oppositely facing suction surface, a leading edge (3, 23) and a spaced apart trailing edge (4, 24), at least one of the blades (2, 22) having means for supplying a flow of oxygen containing gas to the trailing edge (4, 24) of the same blade (2, 22) wherein said means comprise at least two separate gas inlet apertures (6.1, 6.2, 26.1, 26.2) and at least two separate gas passages (5.1, 5.2, 25.1, 25.2), each extending from one of the separate gas inlet apertures (6.1, 6.2, 26.1, 26.2) to a separate group of orifices (7.1, 7.2, 27.1, 27.2) in the trailing edge (4, 24) of the same blade (2, 22) whereas each of the separate group of orifices (7.1, 7.2, 27.1, 27.2) comprises at least one orifice to admit gas out of the corresponding separate gas passage (5.1, 5.2, 25.1, 25.2) to the passing fluid during operation of the runner.
摘要翻译：包括多个叶片（2,22）的水力涡轮机或泵的流道，每个叶片（2,22）由压力表面和相对朝向的吸力表面限定，前缘（2,23）和间隔开的后缘（4,24），所述叶片（2,22）中的至少一个具有用于向其后缘（4,24）供应含氧气体流的装置其中所述装置包括至少两个单独的气体入口孔（6.1,6.2,26.1,26.2）和至少两个单独的气体通道（5.1,5.2,25.1,25.2），每个气体通道从所述单独的气体入口孔气体入口孔（6.1,6.2,26.1,26.2）与相同叶片（2,22）的后缘（4,24）中的单独一组孔（7.1,7.2,27.1,27.2）相连，而每个单独的一组孔（7.1,7.2,27.1,27.2）包括至少一个孔口，以允许在转轮运行期间将气体从相应的单独的气体通道（5.1,5.2,25.1,25.2）中排出至通过的流体。
