Summary The water turbine model can be selected according to the spectrum of the water turbine model, or it can be selected according to the comprehensive map of the water turbine's use range.
The water turbine model can be selected according to the spectrum of the water turbine model, or it can be selected according to the comprehensive map of the water turbine's use range. The selection of the water turbine model is based on the known installed capacity and various characteristic heads of the hydropower station.
1. Select the model based on the water turbine model
According to the determined single machine output and the head range of the hydropower station, a suitable model is selected from the water turbine model spectrum. The range of heads recommended for various models is recommended in the model spectrum. The upper head is limited by the water turbine's structural strength and cavitation characteristics, and the lower head is mainly determined by economic factors. Models suitable for the head range of the power station are optional models.
2.Select the model according to the comprehensive map of the water turbine use range
The comprehensive map of the use range of the water turbine is a graphic drawing the use range of each type of water turbine in a coordinate system with the water head as the abscissa and the output as the ordinate. In the comprehensive map of the use range of water turbines, the use range of each type of water turbine is an oblique box. The two vertical lines of the box are the head range. In the selection, it is determined according to the design head and the single-unit output map. The model of the box where the coordinate point is located is an optional model.
