螺杆空压机和活塞空压机的概述
Overview of screw air compressor and piston air compressor
随着施工企业的发展，各施工单位对机械设备的性能、环保等方面越来越重视，设备配置也朝着环保、节能的方向发展，本文简要对LS20-150螺杆式压缩机和4L-20/8活塞式压缩机的性能作如下比较分析。
With the development of construction enterprises, all construction units pay more and more attention to the performance and environmental protection of mechanical equipment, and the equipment configuration is also developing in the direction of environmental protection and energy saving. This paper briefly compares and analyzes the performance of ls20-150 screw compressor and 4L-20 / 8 piston compressor as follows.
压缩机是以空气为介质的重要动力设备，在国民经济各行业及国防建设中应用十分广泛。国内外信息表明，以螺杆式压缩机代替活塞式压缩机，是国际上空气动力用压缩机发展的最新趋势。目前美、日及西欧等发达国家的螺杆压缩机市场占有量己达90%以上。九十年代以来，我国通用机械压缩机制造业已经批量、规模化生产螺杆式压缩机，螺杆式压缩机在改善生产条件，降低环境噪声，提高气源质量，保障生产正常进行，减少维修时间及费用等诸方面均有着活塞式压缩机无法比拟的优点。
Compressor is an important power equipment with air as medium, which is widely used in various industries of national economy and national defense construction. Information at home and abroad shows that replacing piston compressor with screw compressor is the latest development trend of aerodynamic compressor in the world. At present, the market share of screw compressor in developed countries such as the United States, Japan and Western Europe has reached more than 90%. Since the 1990s, China's general mechanical compressor manufacturing industry has produced screw compressors in batches and on a large scale. Screw compressors have incomparable advantages over piston compressors in improving production conditions, reducing environmental noise, improving air source quality, ensuring normal production and reducing maintenance time and cost.
