Take you closer to the central enterprises
- In the new stage of development, central enterprises have become an important force in building a strong brand
Equipment manufacturing is the backbone of a country's manufacturing industry. At the recently unveiled "Central Enterprise Equipment Manufacturing Innovation Achievement Cloud Exhibition", 21 central enterprises displayed the latest representative achievements of high-end equipment intelligent manufacturing on the "cloud". Come and see which central SOEs have made a stunning appearance.
600 km/h high-speed maglev transportation system
After five years of tackling key problems, China's 600 km/h high-speed maglev transportation system, which was developed by CRRC and has completely independent intellectual property rights, was successfully rolled off the production line on July 20, 2021. This indicates that China has mastered the complete set of high-speed maglev technology and has the engineering capability.
The high-speed maglev with a speed of 600 kilometers per hour is currently the fastest achievable ground transportation. Calculated according to the actual travel time of "door-to-door", it is the fastest mode of transportation within a range of 1,500 kilometers.
It is understood that the high-speed maglev transportation system has successfully overcome key core technologies, the system has solved the problems of speed improvement, complex environment adaptability, localization of core systems, etc. A major breakthrough in engineering technology.
The world's largest diameter full-section hard rock roadheader "Caucasus"
The world's largest diameter full-section hard rock boring machine "Caucasus", developed by China Railway, is rapidly excavating the road tunnel project from Kovisheti to Kobi in the north-south transportation corridor in Georgia. After the completion of this tunnel, the travel time of this section of the road will be shortened from 1 hour to 20 minutes, which will effectively promote the development of the local economy and benefit the local people.
The "Caucasus" is completely designed and manufactured in China by Chinese standards. The roadheader has a diameter of 15.08 meters, a total length of 182 meters, a total weight of 3,900 tons, a maximum thrust of 22,600 tons, and a total power of 9,900 kilowatts. The shining "Made in China" is making every effort to promote the construction of the Belt and Road Initiative.
According to Chen Yun, Secretary of the Party Committee and Chairman of China Railway Group, in addition to the "Caucasus", the company has also independently developed the first domestic high-altitude and cold large-diameter hard rock roadheader "Snowy Pioneer", and the first domestic building component assembly robot "Red A series of "great powers" such as the "Sand" have launched key core technologies such as the construction technology of high-speed railways with a speed of 400 kilometers per hour and the construction technology of railways in alpine and high-altitude areas.
"Gonggong" leads bridge construction technology into the 3.0 era
Behind the "infrastructure maniac", "hard-core" technology is inseparable. The pile-beam integrated intelligent bridge building machine "Gonggonghao" developed by China Railway has realized a new bridge construction mode of factory prefabrication, lean management, modular assembly and intelligent erection, leading bridge construction technology into the 3.0 era.
"Gonggong" uses the Beidou positioning system to drive piling, and realizes a complete set of "aerial" operations for drilling holes, piling, beam erection, and pier assembly. It is suitable for traditional construction methods such as shallow lakes, swamp wetlands, environmental protection areas, and urban bustling areas. The construction of the area can not only greatly improve the construction efficiency, but also reduce the construction dust and noise.China's first "Xuanji" system "Intelligent Manufacturing Chain" was completed and put into production
A few days ago, CNOOC's first intelligent production line of rotary steerable drilling and logging while drilling "Xuanji" system was completed and put into production in Foshan, Guangdong, marking that the "Xuanji" system independently developed by China has officially entered a new stage of large-scale industrialization.
The successful development of "Xuanji" system technology is a revolutionary and subversive technological breakthrough in the field of China's oil drilling and logging. The system can precisely control the drill bit thousands of meters deep underground to "target" the oil layer, "smell" the oil-smelling drill, and even "remotely drive" the drill tool to stably travel 1,000 meters horizontally or obliquely in the thin oil layer of 0.7 meters. The above, at the same time, can realize real-time analysis of stratigraphic data, which is an important magic weapon to greatly reduce the development cost of oil and gas fields and efficiently develop offshore oil and gas resources, representing the highest level of drilling and logging technology development in the world today.
As of March 2022, the "Xuanji" system has been successively applied in the Bohai Sea, South China Sea, East China Sea and major land oil and gas fields, and has been extended to Iraq, Indonesia and other countries.
Beidou networking, high-speed rail speeding, "eyes of the sky" looking at the sky, "dragons" exploring the sea... In recent years, central enterprises have been based on technology and self-reliance, focusing on industrial transformation and upgrading, promoting the transformation from Made in China to Created in China, China Speed to China Quality, The transformation of Chinese products into Chinese brands has achieved a series of breakthrough and landmark achievements.
Tan Zuojun, deputy director of the State-owned Assets Supervision and Administration Commission of the State Council, said that facing the future, state-owned and central enterprises will promote the integrated development of innovation chains, industrial chains, and supply chains, and strengthen the endogenous power of "China's intelligent manufacturing"; accelerate industrial transformation and upgrading, and broaden the "China intelligent manufacturing". Achieving the path; anchoring the development goal of building a world-class enterprise, striving to be the vanguard of "intelligent manufacturing in China". Editor / Xu Shengpeng
