Research on Key Manufacturing Technology of Baihetan Zero-counterweight Runners

The runner of hydro turbine is a key component of energy conversion. Hydropower manufacturing enterprises have been seeking design and process technology improvements to improve the manufacturing accuracy of runner, and the pursuit of runner zero-counterweight is one of the important indicators. Although the runner manufacturing process has a complete process and technical support, it is still very difficult to achieve the zero-counterweight manufacturing of runner. Through the quality testing and inspection in the whole process of runner manufacturing of Baihetan Hydropower Station, and the strict control analysis of process data and main processes, the zero-counterweight manufacturing of turbine runner with long-by-short blade in Baihetan Hydropower Station is realized, which can provide references for the key technology of zero-counterweight or less counterweight runner manufacturing.
