History of centrifuge: the 18th century industrial revolution, with the rapid development of the textile industry, in 1836 there have been cotton dryer. 1877 In order to meet the needs of the cheese processing industry, invented a separator for separating the milk. Development of the 20th century into the compressor, with the development of comprehensive utilization of oil, the requirements of the water, solids, tar-like materials, etc. is removed so that the use of heavy oil as fuel. 50 years of successful development of the automatic slagging slagging disc separator piston, to the 1960s evolved into the perfect product. With Modern environmental protection, waste management needs of the development prospects of the mine air compressor, the requirements of industrial wastewater and sludge dewatering process are high, thus causing the decanter centrifuge, disc separator and a three-foot further development of bottom discharge centrifuge. Especially the development of horizontal spiral unloading settlement centrifuge rapidly. With the continuous development of the national economy of various industries, various types of centrifuges are constantly upgrading, and new types of centrifuges are emerging. Screw compressor experienced the following periods: 1937, Alf Lysholm in SRM company successfully developed two types of screw compressors experimental prototype, and achieved satisfactory results. In 1946, in Scotland, the British company James Howden compressor development, the first to get a license from the production of screw compressors Swedish SRM company. Subsequently, Europe, the US and Japan companies are starting to get this license from Sweden SRM company, engaged in the production and sale of screw compressors. First developed the screw compressor is oil-free screw compressors. 1957 injected screw air compressor into the market applications. 1961 and the successful development of the refrigeration compressors and oil-injected screw compressor screw technology. Then with the rapid development of Chinese economy, more and more attention to the state of the machinery industry, such as mining machinery and petrochemical machinery. Along with the development of these machines, the development of the industry is also in full swing compressor, air compressor repair, air compressor accessories has also been a rapid development. Air compressor industry has emerged from the traditional industries, with strong support of science and technology and innovation to make reform commission basis points. Air compressor has become the representative of entrepreneurship. Qin Wei since the plant since the scroll compressor compressor prospects, focused on piston compressor, screw air compressor, permanent magnet frequency conversion air compressor, air compressor parts, etc., to lead the development direction of the industry, with more than patent rights. German technology made in China, North Manchester compressor play a role in the market pillar mid-stream, the North West air compressor will become a pillar industry of China's air compressor industry, and promote sustainable economic development, promote China's economic rapid development. Qin Wei Air (FIG), the development of screw air compressor, air compressor developed by Compressor Co., Ltd. Xianyang Qin Wei. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) to provide "air compressor and accessories, general machinery parts," such as business, the company has "Wei Qin brand, Coatler card (C?te children)" and other brands. Focus on compression, separation equipment and other industries, have higher visibility in Xianyang. Welcomes inquiries, contact: Liu.
