The current market in the strong guidance and support of national policies, along with the transition to the world machinery manufacturing power, the rapid development of our air compressor industry. With the expansion of industry consolidation, especially in the context of the financial crisis, the market share has gradually concentrated to a small number of competitive enterprises, the production concentration of the air compressor industry gradually rising trend. Moreover, in the original production of many state-owned enterprises on the air compressor air compressor manufacturers Which is good, private enterprises have sprung up everywhere, foreign beachhead into the Cottle compressor manufacturers, China's air compressor market has formed a state-owned and private and foreign separate categories of competition, competition is increasing. China is one of the world's fastest growing industry, so the air compressor manufacturing is irreplaceable; as long as the industry still exist, industry is still developing, the market share of air compressors will never fall, to provide technical related machinery and equipment manufacturing industry will not be replaced. Although in recent years, with the acceleration of technological progress, all kinds of new technologies, new materials, new equipment in the field of air compressors abound. Competitive alternative to the existing air compressor manufacturer is a serious challenge. From our present situation, an alternative competition for the new entrants to the market provides a good entry point and potential competitive advantage. The main fault 1, piston oil-free air compressor piston rings and packing devices are aircraft without greasing. Under normal circumstances, after essentially pure compressed gas free of oil, but because of the oil scraper ring often scraping the oil is not complete, sealed well, often resulting in oil filler device even went on the piston ring, so that the compressed gas oil. In addition, the exhaust temperature is high, sometimes up to 200 ℃; cooler clogging famous compressor manufacturers, so that the cooling effect is not good; piston ring touches the oil, are particularly vulnerable to wear and tear; beat leak valve; cylinder liner wear. 2, screw-type air compressor screw air compressor malfunction little, as long as regular maintenance of oil separator, air and oil filters, etc., will be able to ensure their normal operation.
