1. The United States joined the new technology, with over 30 years history of R & D into production, the output value of 43 million, the annual output of 800 units. .2 Northwest ranking first in the industry. Owned Cottle 'licensing screw air compressor manufacturing technology has reached world-class level, 3 national key projects have been selected in the Three Gorges, the Qinghai-Tibet railway is the national professional production, One base compressor developed high performance air compressor brand configuration, a European import brands hosts oil-free compressor, large rotors, low speed design. 2.SKF precision bearings, high-quality seals, reliable brand air compressor supply, energy saving, long life 3. famous brand four motor, F class insulation rating, IP54 degree of protection, the use of reliable, high-quality Baosteel cold rolled plate cover with baking temperature 250 ℃, bring ultra-long anti-corrosion, durable and efficient energy-saving and low operating costs, 1. Highly intelligent, automatic adjustment for optimal operational state body, 2. energy efficient while air compressor brand offer, extend the life of the body, more than 4000 hours maintenance intervals major 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 clogged, 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. Oil-free air compressor brands, well-being brand air compressor, compressed air provided by the Xianyang Qin Wei Qin Wei Compressor Co., Ltd.. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) strong, credible, Xianyang in Shaanxi compression, separation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Qinwei Air into the brilliant and you work for a better future!
