Single screw compressor prototype comes from is called "compression conversion device," the patent in 1960 made by the British JWGoodyear Xinmai En France (B.Zimmern) is proposed on the basis of a single screw compressor Cottle · Compressor in 1962, developed the first machine test Qin Wei air compressor, turn the machine crude for 5000r / min, power 7.46Kw, withstood more than 1000h life test. In addition to the characteristics of a single screw compressor rotary compressor has a simple structure, small size and characteristics of the valve assembly without external air compressor, but also has many unique advantages. These advantages are due to the two-wheel screw-symmetric configuration unit volume due to a reasonable volume 2. 1. Structure, demonstrated the gap empty plot 3. low noise and vibration. Single screw compressor power balance is good. Necessity and hydraulic systems for compressed air purification treatment of the cleanliness of hydraulic oil have higher requirements as pneumatic systems for compressed air also have higher requirements. Air discharged from the air compressor can not be directly used pneumatic devices, air compressor intake air containing moisture and dirt from the atmosphere, compressed air after the temperature is increased to above 100 ℃, when the air compressor in the lubricating oil part becomes gaseous. Thus, the compressed air discharged from the air compressor becomes a high temperature gas containing oil, water and dust. If such a compressed air directly to the pneumatic system of air compressor price, due to poor air quality, and the reliability and service life of the pneumatic system is greatly reduced, resulting losses are often much higher than the cost and maintenance cost air source treatment unit , so the correct selection of air handling system is absolutely necessary. Screw air compressor, air compressor, air compressor Qin Wei, Cottle brand authority provided by Compressor Co., Ltd., Xianyang Qin Wei. Xianyang Qin Wei Compressor Co.
