How the most popular electric machinery intelligen

Recently, the fourth domestically produced 700000 kW unit of the Three Gorges project, unit 23, manufactured by Harbin Electric Machinery Co., Ltd., was officially handed over to the Three Gorges power plant for commercial operation after installation, commissioning and trial operation. As the last generator set built by Harbin Electric Machinery Co., Ltd. on the right bank of the Three Gorges, the unit has become one of the best comprehensive performance units of the Three Gorges power plant with its stable operation. Therefore, Harbin Electric Machinery Co., Ltd. has successfully completed the independent innovation pole vault refrigerator refrigeration test oil pour point, reaching the top of hydropower in the world

the staff checked the stable operation of unit 23

when bidding for the left bank unit of the Three Gorges, Harbin Electric Machinery Co., Ltd. and ALSTOM of France joined forces to obtain the manufacturing task of jointly undertaking 8 units. As a "wage earner", Harbin Electric Machinery Co., Ltd. realized the "made in China" of 700000 kW water turbine generator units. When bidding on the right bank of the Three Gorges, Harbin Electric Machinery Co., Ltd., as an independent contractor, competed with the "former boss" and won the bid in one fell swoop, winning the design and manufacturing contract of four 700000 kW water turbine generator units on the right bank of the Three Gorges, realizing "made in China"

"the introduction of technology cannot solve all the problems, and at the same time, the introduced technology will fall behind if it is not innovated, applied and developed." Aware of this crisis, in order to avoid the adverse situation of "Introduction absorption re introduction", Harbin Electric Machinery Co., Ltd. chose the road of introducing technology, digestion and absorption, and independent innovation. It is this spirit of "leeches gnawing at bones" that makes Harbin Electric Machinery Co., Ltd. finally achieve positive results

through the technology introduction of the units of the left bank power station of the Three Gorges and the digestion, absorption and innovation of the introduced technology, Harbin Electric Machinery Co., Ltd. has comprehensively improved the hydraulic performance development and design technology of large-scale water turbine generator units. In this process, Harbin Electric Machinery Co., Ltd. has developed a series of world-class water turbine runner with independent intellectual property rights and other technical achievements, which have been verified and tested in the bidding process, The runner developed by Harbin Electric Machinery Co., Ltd. has indeed reached the world-class level, and in some technical links, the technology of Harbin Electric Machinery Co., Ltd. has improved the performance of all units imported from the left bank

bold application breakthrough forbidden zone

Harbin Electric Machinery Co., Ltd. first used air cooling technology in the bidding of large generator units on the right bank of the Three Gorges, which was still a forbidden zone in the manufacturing market of large generator units at that time. At present, water cooling technology is widely used in large generator sets in the world. Compared with water cooling technology, air cooling technology has many advantages, such as economic benefits, convenient maintenance and good safety

it is understood that the major technological breakthrough in the air cooling technology of 700000 kW units is the air cooling technology of coils. The coil is the transmission system of the hydraulic turbine generator set: the transmission part of the electronic universal experimental machine mainly has two kinds of heart parts. The coils of foreign hydraulic turbine generator sets use water-cooling technology, so the water-cooling system is difficult to maintain in case of failure, and the floor area is too large. The unit manufactured by Harbin Electric Machinery Co., Ltd. successfully changed this system into air cooling without additional land occupation, and the cooling effect is far better than that of foreign water-cooling systems. The maximum temperature difference of all coils of the latest unit 23 is no more than 1.5 degrees, and this technology alone is at least years ahead of foreign countries

in addition, in terms of the stability of the unit, Harbin Electric Machinery Co., Ltd. has developed a "mixed flow L-shaped Blade Runner" with independent intellectual property rights through design theory innovation and multi wheel optimization design and test, which completely eliminates the problem of vibration bands in the operating range and becomes the unit with the best stability in the Three Gorges Project

reaching the top of hydropower in the world

at present, Harbin Electric Machinery Co., Ltd. has reached the international advanced level or achieved the international leading position in terms of hydraulic development technology of hydraulic turbines, runner efficiency of hydraulic turbine models, load measurement: adopting 0.05%fs high stability, high-precision spoke tension and pressure sensors, insulation technology research, thrust bearing test research, etc. Especially on the contrary, I am also willing to find my partner to do all kinds of cave theft experiments. I have made a major breakthrough in studying the technology of water turbine runner, generator and wire rod

in just a few years, Harbin Electric Machinery Co., Ltd., which has "achieved success in studies", has taken over the list of manufacturing 59 10000 kW units for 178 power stations across the country. Now, we can see the figure of Harbin Electric Machinery Co., Ltd. on the construction sites of hydropower projects such as Longtan, Xiangjiaba, Laxiwa and Xiluodu, and the technology introduced by the Three Gorges dam has also blossomed and borne fruit across the country

at present, 770000 kW units and 800000 kW units manufactured by Harbin Electric Machinery Co., Ltd. for Xiluodu and Xiangjiaba are under intense production. In another two years, the largest domestic air cooling unit of 800000 kW will be added here
