3 Series of turbine products
3.1 Product series
For the product series of small and medium-sized axial-flow and mixed-flow turbines, please refer to the "Table of product series of small and medium-sized axial-flow and mixed-flow turbines". 3.2 Device type
For the device type of axial-flow and mixed-flow turbines, please refer to Figure 1. 3.3 Size series
The diameter size series of small and medium-sized axial-flow and mixed-flow turbine runners is specified as: 25, 30, 35, 42 (40), 50, 60, 71, 8480), 100, 120, 140, 160, 180, 200, 225, 250, 275, 300, 330cm. 3.4 Scope of use
The scope of use of the small and medium-sized axial flow and mixed flow turbine product series is shown in Figure 2. The scope of use of each series of turbines is shown in Figures 3 to 20. 4 Turbine product model representation
The turbine product model consists of three parts. The first part is the turbine runner model, the second part is the turbine device type, and the third part is the turbine runner diameter size (cm). The three parts are connected by a connection symbol "_\".
