Shaanxi Drum axial compressor design and manufacturing technology into the forefront of the world

During the "10th Five-Year Plan" period, Shaanxi Blower (Group) Co., Ltd.'s annual output value rose rapidly from 300 million yuan to 2.5 billion yuan, and the main economic indicators were double-digit growth, ranking among the top 500 machinery enterprises in the country. So far, Shaanxi Drum has provided a total of more than 10,000 sets of wind turbines for the country's economic construction, filling more than 20 technological gaps and developing more than a hundred new products. It has formed its own core technology and has maintained its leading position in the world of similar devices in axial compressors and industrial process energy recovery power generation equipment.
By changing the traditional business ideas, Shaanxi Drum has explored and practiced a commercial operation mode that relied on scientific and technological innovation and management innovation, and successfully implemented the transformation, that is, from a single fan manufacturing to a turbine machinery core, providing customers with system integration. Large-scale enterprise groups and systems services.
It is understood that since the introduction of the design and manufacturing technology of the A- and AV-type full-static vane adjustable axial compressors of the Swiss Sulzer Company in 1979, Shamboo has absorbed more than 10 years of innovation and reinvented it, and it has fully realized localization by 1991. . Up to now, the company has achieved 524 (sets) and 189 sets (sets) of axial compressors and industrial process energy recovery power generation equipment that have been independently developed using technologies and imported, digested, and reinvented foreign technologies. In 2005, the annual output of axial compressor reached 90 sets, which broke the world's highest record of 32 axial compressors produced by Sulzer of Switzerland. In September of the same year, the product was awarded the title of “China Famous Brand”. At present, the domestic market share of the product is above 95%.
Axial flow compressors are highly efficient and energy-saving products. They are 10% more efficient than general centrifugal compressors and have good economic and social benefits. They can meet the metallurgical industry's 300 to 5,800 cubic meters of blast furnace and petrochemical industry, 600,000 to 4 million tons/year. Catalytic cracking equipment and supporting needs in the pharmaceutical industry, chemical industry, large air separation plants, aviation industry, liquefied natural gas facilities and other fields. The AV100-17 axial compressor, which is supplied to Shougang's 2580 cubic meter blast furnace, effectively increased the blast furnace smelting intensity and increased the production of hot metal. The annual added production value was 200 million yuan, and the new profit and tax was 5 million yuan.
Industrial process energy recovery power generation equipment is an energy-saving and environmentally friendly product that the country vigorously promotes. Shaanxi Drum continues to innovate in energy recovery turbines, equipment distribution power generation systems, and engineering complete sets, forming a number of patents. In accordance with the needs of users, Shaanxi Drum has developed the world's leading furnace top pressure automatic control technology, wet and dry TRT technology, adjustable first-level vanes, and full-static adjustable blade technology. Shaanxi Drum has therefore been identified as the only research and development base for environmental protection and energy saving recovery turbines. Recently, the country has formally included Shaanxi Drum Industrial Process Energy Recovery Device as one of the major technical equipments required for installation in the national “Eleventh Five-Year” ten energy-saving projects.
At the end of October 2005, Shaanxi Drum successfully won the bid for Brazil's Gerdal 1750 cubic meter TRT project and became China's first company to export TRT devices. At present, two TRT turbine units are being designed and manufactured for the 3,200 cubic meter blast furnace of TATA Steel of India with a recovery power of 15,000 kW.
