    摘要: A runner for a hydraulic turbine or pump has a plurality of blades. Each of the blades is defined by a pressure surface, an oppositely facing suction surface, a leading edge and a spaced-apart trailing edge. At least one of the blades has a device for supplying a flow of oxygen containing gas to the trailing edge of the same blade. The device includes at least two separate gas inlet apertures and at least two separate gas passages, each extending from one of the separate gas inlet apertures to a separate group of orifices in the trailing edge of the same blade. Each of the separate group of orifices has at least one orifice to admit gas out of the corresponding separate gas passage to the passing fluid during the operation of the runner.

    摘要: The invention relates to a line system for a water power plant, comprising the following features and components: a turbine having a turbine impeller and a turbine spiral housing, a pump having a pump impeller and a pump spiral housing, the two spiral housings being arranged to run in opposite directions to one another, a shaft on which the turbine impeller and the pumpkin impeller are arranged in a rotationally fixed manner, an electric machine that has a drive connection to the shaft or can connected thereto, the pressure lines of the two spiral housings opening in a common line pressure line, a turbine pressure line for introducing water out of the main pressure line into a pump turbine in turbine operation, a pump pressure line configured as a bend for introducing water out of the pump turbine into the main pressure line in pump operation or back through the turbine pressure line to the pump turbine in a hydraulic short circuit, and a branch part to which the main pressure line, the turbine pressure line and the pump pressure line are connected. The invention is characterized by the following features: the flow cross section of the bend is larger at the outlet therefrom than at the inlet thereto.
