Compressed air quality increase for rolling stock pneumatic systems based on energy efficiency

The energy efficiency increase problem for railway rolling stock pneumatic systems compressed air preparation is directly connected with its purification and drying technology choice. In the presented materials in the article, the authors find a solution to the problem based on realization analysis of different factors that affect compressed air quality, purification and drying technology choice, as well as based on energy efficiency analysis. To realize the energy-saving events at railway rolling stock compressed air preparation, the authors suggest performing factor analysis influencing on compressed air purification method choice to consider pneumatic system as a module scheme and to employ the modernized construction of the locomotive main tanks.
