HXD2型机车风源净化系统的合理配置浅析

摘要

The reasonable allocation of internal parts of locomotive wind source purifying system has a directly impact on air quality of loco⁃motive wind source purifying system. The article described that allocation and selection of internal parts of locomotive wind source purifying system such as filter, blow-off valve, dryer etc which affect the air quality. Dryer selection and regeneration air consumption rate was de⁃scribed particularly. Through the results of dryer type test, improving that the allocation of HXD2 locomotive wind source system is reason⁃able, and the existing air quality of wind source system meet the air using requirements.%　　机车风源净化系统内各部件的配置合理性，直接影响机车风源空气质量的好坏。介绍了影响空气质量的机车风源系统内各部件（如过滤器、排污阀、干燥器等）的布局原则与选择方法，侧重介绍空气干燥器的选型和再生耗气率计算。通过HXD2机车干燥器的型式试验结果，验证了其风源净化系统的配置合理性，并能满足HXD2机车的空气质量要求。
