In recent years, China has achieved globally remarkable accomplishments in hydropower development. Among these, the invention and application of the automatic turning device have played a crucial role in ensuring stable and efficient operation of generating units, as well as enhancing the overall quality of hydropower projects—thus contributing significantly to the high-quality growth of China's hydropower industry.
In hydropower projects, turning the rotor is a critical operational procedure for inspecting and adjusting components related to the hydro-turbine generator set. This task is complex to perform and demands precise control over the unit’s rotor and stator, making it prone to equipment damage. As a result, for a long period of time, the rotor-turning process was carried out manually—resulting in high labor intensity and extended project timelines.
In 1992, Pang Zijing, an expert in hydropower engineering, successfully developed the first-generation automatic turning device, significantly reducing the time required for the turning process. In 2006, Pang Zijing founded Qingdao Zhengli Power Equipment Co., Ltd. Since its establishment, the company has continuously innovated and advanced the development of automatic turning devices, driving their steady evolution and improvement. Today, these cutting-edge automatic turning systems have been successfully implemented in over 300 major projects, including the Three Gorges Project on the Yangtze River, Liujiaxia Dam, Xiaolangdi Project, Fengman Hydropower Station, Xin'anjiang Dam, the Guangdong-Hong Kong Water Supply Project, and the Pearl River Delta Water Resource Allocation Project.
