货运机车用压缩机型式对比分析及选型

Comparison and Selection of Compressor Type for Freight Locomotive

通过对活塞式空气压缩机和螺杆式空气压缩机技术参数及使用性能的对比分析,明确两种类型压缩机之间的差异。在此基础上,对列车用风进行详细计算,确定列车用风量的大小,再根据用风量的大小确定压缩机排气量的大小,最后对货运机车设计中压缩机选型提出参考建议。

This thesis, through the comparison of technical parameters and performances between piston air compressor and screw air compressor, determines the differences of the two types of compressors. Based on this, it puts forward advices on the choice of compressors during the design of tain by air outputs of compressors, which are defined by the required air volumes that are decided through detailed calculation of air volumes for frieight locomotive.
