摘要
针对青藏线恶劣的自然环境,DF7G型青藏铁路调车机车的辅助系统进行了适应高原的优化设计。对冷却系统、预热系统、燃油系统、机油系统和进气系统分别进行了不同于平原调车的机组选型。在DF7G型模块化机车的基础上,通过优化机组性能,达到提高整车质量,使机车更好地在青藏高原上运用的目的。
In view of rigorous environment in Qinghai-Tibet railway,optimization design of auxiliary system of DF_(7G) shunting locomotive for Qinghai-Tibet is performed.Model selection,that is different from one for plain,has been completed for systems such as cooling,preheating,fuel,oil and air intet systems.Based on DF_(7G) modularized diesel locomotive and by optimizing set performance,the quality of the locomotive,as a whole,has been improved.
