Technology introduction and cooperative production
1979, Shaanxi Drum introduced a set of axial compressor technology from Sulzer Company (now Mann-Turbine Company) in Switzerland through licensing trade, and has independently designed and manufactured nearly 700 axial compressors since the 1980s. This technology is widely used in metallurgical blast furnace, catalytic cracking, nitric acid, fermentation, pharmacy, PTA and other industries.
1994 Shaanxi Drum signed a cooperative production agreement with the former Sulzer Company of Switzerland. After Sulzer Company was merged into Man-Dobo Company in 2002, it continued to sign an agreement with Man-Dobo Company for cooperative production of centrifugal compressors. In recent years, Shaanxi Drum has purchased several advanced basic stages of Zhenqi centrifugal compressors from Germany and St. Petersburg University in Russia. Shaanxi drum not only pays attention to design technology, but also attaches great importance to the improvement of manufacturing technology and processing and manufacturing level Since 2000, Shaanxi Drum has invested more than 70 million yuan to upgrade its equipment, which makes the processing and manufacturing level of Shaanxi Drum at the leading level in the fan industry. At the same time, specialization and cooperation network will be established, domestic specialized processing resources will be fully utilized, Shaanxi drum production capacity will be greatly improved, and all cooperative production transformation projects will be completed according to the contract requirements. Through the implementation of cooperative production transformation project, Shaanxi has mastered the processing and manufacturing technology of large-scale air separation centrifugal compressor.
Shaanxi Drum has upgraded and improved the original imported technical calculation software for many times, and successfully transformed the imported technology into its own technical pneumatic calculation software with world-class level. Master the pneumatic design technology of air and nitrogen oxides, synthesis gas, ammonia, carbon dioxide, circulating gas and other special media compressors.
System technology and complete technology
Shaanxi drum is the earliest enterprise in the industry to study and apply system technology and complete sets of technology. Through the study of process system and complex unit, Shaanxi Drum has mastered the system technology related to compressor and the complete set technology of complex unit. For example, Shaanxi Drum has designed more than 200 large-scale complex devices, including more than 40 nitric acid devices; More than 30 sets of large-scale projects of 600,000-ton PTA plant have been contracted, including Kincaid's 270,000-ton/year nitric acid plant project. The instrument and automatic control technology of Shaanxi Drum originated from the introduction of technology. After years of continuous development combined with domestic reality, it has been recognized and praised by domestic customers, especially the performance of large and complex units and the cooperation with process devices. The reliability, integrity, rationality and advancement of automatic control system always maintain the leading position in the industry. For example: PTA plant, nitric acid plant, catalytic cracking plant, air separation plant, etc. , undertake design, application software programming, system debugging and trial operation, user training, etc. Instruments and automatic control systems imported from abroad.
