With the rapid development of the economy in recent years, industry concentration has increased, supply further concentrated to large enterprises, industrial air compressor to the layout of the gradual development of a reasonable situation. By promoting the strategic restructuring of the economy, many companies out poor quality, excellent companies have identify the location, highlight the main industry, bigger and stronger, to the powerful combination of technology and equipment to assume major national projects. In related policies, in response to the global financial crisis on China's economy in early 2009, the country has developed a series of economic stimulus programs that focus on industrial restructuring and rejuvenation including downstream petrochemical, metallurgical, including gas compressor Ten industries. China has experienced a compressor start, grow in two phases, has entered the stage of stable development. With the rapid development of air compressor industry, the air compressor market concentration gradually increased, gradually formed a group of leading companies, these enterprises to continuously improve the competitiveness of industry consolidation. Although the rapid development of China's compressor industry, but the industry still has some problems. At present, China air compressor market, foreign companies still occupy the lion's share of the market. Because our technology is weak, foreign high-end products in the market to occupy certain advantages; and small-scale enterprises, the distribution of scattered, low industrial concentration; the lack of high-end technology, the large proportion of low capacity; product homogeneity. In recent years, the global energy crisis, resulting in energy and raw materials prices are rising, rising costs for manufacturing companies to bring pressure on operators, resulting in shrinking profit margins, the demand for air compressor reduction. 2010 market capacity of the air compressor is about 20 billion yuan, is expected to remain stable future growth, market capacity in 2015 will exceed 30 billion yuan. Compressor technology development trend of China in recent years, with the rapid development of electronic technology, applications compressor technology has been rapidly expanding, and in a variety of automated production line has been widely used. Development of pneumatic robots and flexible automatic technology, the combination of compressor technology and microelectronics technology, modern control theory, so that the air compressor technology into the switch control system "closed loop - the ratio - Servo" control system, so that the control accuracy is a qualitative improvement. Today, air compressor technology has become one of the key technologies of industrial drives and control. Modern air compressor technology is moving small, lightweight, mechatronics direction, various low-power, non-oil, development and application of precision pneumatic components, air compressor technology makes this development has far far from breaking the original applications, at the high end of microelectronic chips, bio-engineering, medicine, food, and military control has been widely used. Future trends compressor industry is now the government machinery industry increased emphasis degrees, the air compressor industry will become a rapidly developing situation pomp.
