Since 2005, the core technology level of screw mainframes in China has been significantly improved. The screw mainframe rotor type and structural design have made great progress, and the mainframe design and manufacturing have been localized.
At present, China's compressor manufacturing industry has formed a series of micro compressors, power compressors and process compressors, about 500 different specifications, nearly 20 structural types, and more than 30 compressed gas media.
By 2019, there were more than 480 compressor manufacturers above designated size, and more than 120 enterprises with output value of 20 million to 2 billion yuan. The domestic screw compressor mainframe exceeds 350,000 units per year, the air compressor complete machine output value is more than 50 billion yuan, and the output value of various types of compressors is over 70 billion.
After 70 years of development, China's compressor manufacturing industry has formed a strong industrial system with complete categories, largest scale, independent technology, good reputation and double the production capacity of all foreign markets. Quality and technology rank among the best in the world and become an important pillar industry for the development of the national economy.
