From 1992 to the present, for 30 years, Pang Zijing has always given all his life to his own automatic turning gear business, and has carried out four upgrades to make it more perfect. Today, he is proud of his achievements, but at the same time says that he cannot stop his progress because of his success.

On December 30, "China Brand Archives" broadcast a documentary program entitled "The Power of Persistence", focusing on Qingdao Zhengli Power Equipment Co., Ltd., the silent defender of China's hydropower industry. Through in-depth interviews with the company's general manager Pang Zijing and the former director of Fengtan Hydropower Plant Yang Changxi, the touching stories of struggling in the field of hydropower were shown, and the audience felt the power of those who silently persevered for China's hydropower industry.

Pang Zijing, an old man with gray hair but still young and energetic, has been on business trips almost 300 days a year for the past 30 years. In the interview, he admitted that his family did not understand and his friends did not support him, but he stuck to his faith and did only one thing in his life-to fight silently for the cause of hydropower.

In 1997, Pang Zijing and Yang Changxi met for the first time. At that time, Pang Zijing shared the application of automatic turning gear at the technical exchange meeting, which aroused Yang Changxi's strong interest. The encounter opened a close cooperation between the two in the hydropower industry.



Hydropower industry in China has a hundred years of history, is one of the world's largest hydropower countries, hydropower operation has been dependent on manpower. However, this traditional turning method has the problems of high labor intensity, long time and large economic loss, which has brought great troubles to the hydropower industry.

Yang Changxi described this problem in the interview: the labor intensity of the turning wheel is high, which requires a lot of manpower, ranging from four days to 30 days. At the same time, there are high risks, ranging from minor injuries to serious injuries, and even casualties.

Pang Zijing's automatic turning gear came into being. In the interview, he reviewed the ideas that were brewing in his mind in 1992, and with the desire to solve the problem of adjustment and maintenance of the hydraulic turbine unit shafting, he began a long road of research and development.



In 1998, Pang Zijing brought the first automatic turning gear to the Xiangxi Fengtan Hydropower Station in Hunan Province, but the first use ended in failure. At this critical moment, the support and encouragement of Fengtan Hydropower Station became the driving force for Pang Zijing to revitalize. He returned to Shandong with the equipment to carry out renovation and upgrading.



After a year of painstaking research and improvement, Pang Zijing once again returned to Fengtan Hydropower Station with the improved automatic turning gear. This time, everything went smoothly, and the automatic turning gear was successfully applied to the overhaul of the turbine. Since then, Pang Zijing's automatic turning gear has been widely used in hundreds of hydropower stations across the country.

During the interview, Yang Changxi recalled the moment when the gear broke, but he also expressed his belief in the feasibility of this technology. This technology not only solves the problem of the traditional turning method, but also improves the efficiency, and does not have any unsafe incidents during use.

From 1992 to the present, for 30 years, Pang Zijing has always given all his life to his own automatic turning gear business, and has carried out four upgrades to make it more perfect. Today, he is proud of his achievements, but at the same time says that he cannot stop his progress because of his success.

Through the wonderful presentation of the documentary, we saw a touching story of an ordinary person in China's hydropower industry who paid silently and pursued innovation. Pang Zijing's persistence and efforts show how an individual can remain persistent in the face of difficulties and setbacks and constantly pursue innovation and progress. This is not only a documentary about technological innovation, but also a true portrayal of human nature, faith and struggle.
