On February 28th, the hydro-turbine cylinder valve independently developed by Harbin Electric Machinery Co., Ltd. passed the appraisal of experts from China Machinery Industry Federation, China Three Gorges Corporation, and China Huaneng Group. The conclusion is: This product fills the historical gap of Harbin Electric Power's project and reaches the national leading level.
As the company's first self-developed large-scale cylinder valve, Harbin Power owns the independent intellectual property rights of the product. According to reports, in June 2004, Harbin Electric signed a contract with Guizhou Beipanjiang Hydropower Development Co., Ltd. for 4 sets of Illuminated Water Valves. After the waterless operation of the simulated power station, the valve switching test, the valve closing test, the valve opening and closing test, the valve fully open stability test, etc., the indicators meet the design requirements, good synchronization performance, safe and smooth operation process, No jamming phenomenon.
This research work has surpassed the mechanical synchronous adjustment technology in the past and it uses the advanced synchronous electrohydraulic adjustment technology. In the experiment, a computer data acquisition and processing system was used to verify the consistency between the actual movement trajectory of the product and the internal control system. Experts believe that the successful development of the first cylinder valve has a high starting point and unique characteristics, signifying substantial progress in Harbin Power's technological R&D capability and manufacturing level in the field, laying a solid foundation for the future manufacture of large-scale units.
It is reported that China will soon have a Zaduo, Xiluodu and other giant power plants that require such products will be put into operation. Harbin Electric will further strengthen its technological innovation and strive to achieve even better performance in the future.
