March 28, Dongfang Turbine Co., Ltd. independently developed supporting the million-kilowatt-class ultra-supercritical unit feed water pump turbine test success. Reporters at the East Turbine Turbine Division test site to see the scene, with the steam turbine speed gradually increased to the target value, the control panel shows the performance indicators fully meet the design requirements, in warm applause, from the Design Institute, Power Plant And other industry experts and users have witnessed this historic moment, marking the future construction of China's million-kilowatt-class ultra-supercritical thermal power units, is no longer the import pump-turbine dominated the world situation. Feedwater pump turbine is one of the main components of thermal power plant cycle, especially in the high-parameter large-capacity ultra-supercritical unit occupies an important position, its safe and reliable operation, a direct impact on the operation of the entire power plant equipment. Because of its high requirements in terms of safety and reliability, automation level and load adaptability, it is only one of the few companies in the world that a million-kilowatt turbine feed water pump turbine can be designed and manufactured. In recent years, in order to achieve energy conservation and emission reduction and improve primary energy utilization, the market demand for ultra-supercritical million-kilowatt efficient generating units is more and more. In order to occupy commercial opportunities and technological commanding heights as soon as possible, from 2006, In the digestion of the past 300,000 kilowatts, 600,000 kilowatts to the introduction of steam turbine technology on the basis of self-developed million-kilowatt turbine pump, thanks to years of accumulated technical strength and tens of millions of inputs, with less than a year Dongfeng It completed the development and design, and completed by the end of 2007. According to experts, the aircraft technology is leading in the domestic advanced world and has completely independent intellectual property rights, the overall program design using the model with the world's advanced level of flow design technology and new structural design technology, with large power capacity , A wide range of speed to adapt to changes in conditions of operational performance, high safety and reliability advantages, especially the last stage moving blades height reached 411mm, creating an international precedent. According to the machine user Datang International Chaozhou Power Generation Co., Ltd. Deputy Minister of Expansion Yang Kai lock revealed that the aircraft in accordance with the design and manufacture of fast-moving unit will be shipped in April to the power plant in general, can be put into operation during the year. Zhang Zhiying, general manager of Dongfang Turbine Co., Ltd. said that the successful development of the first Million-Feedwater Pump Turbine not only filled the gaps in the domestic market, but also had a wide range of application prospects in the market. It also enabled Dongfang's technological development to a new level, with leading products in the horizontal and vertical On the formation of series, the next step for the development of air-cooled million-series water pump turbine to lay a solid foundation.
LED point light source is a new kind of energy conservation and environmental protection decorative light, using LED cold light source, the built-in microcomputer chip, can be arbitrary programming control, multiple synchronous change, monochromatic changes can also be realized synchronous colorful gradient, jump, scanning, running water light color change effect and multiple LED point light source form a lattice screen.All kinds of pictures, text and animation effects can be changed. It is a supplement of linear light source and flood lighting, which can meet the design requirements of the point line surface.
