Hydro Turbine Runner is a key component for converting water energy into mechanical energy. The accuracy of the blade profile is an important factor affecting turbine efficiency, output, cavitation and operating life. It is an important indicator to measure the level of turbine manufacturing.
The manufacturing process of the turbine runner blade is complicated and has many processes. Although the production process is very different, it generally includes dozens of processes such as material preparation, blank manufacturing, forming, and heat treatment. Therefore, the manufacturing technology of runner blades is often used as a symbolic indicator to reflect the competitiveness of turbine equipment manufacturers, and is highly valued by hydropower industries around the world.
