柴油机的增压空气采用空气直接冷却技术在大功率内燃机车上应用已经有较多报导,它既改善了内燃机车的运行性能又提高了运用的可靠性,本文通过内燃机车空冷装置主要部件空—空冷却器和空冷风扇的设计,对主要参数选择进行分析,供空冷装置设计参考。(一) 空—空中冷装置简介与组成1.空—空中冷装置简介目前机车柴油机进气都进行不同程度的增压,经过增压的空气均经中间冷却后进入柴油机,以提高进气平均有效压力和进气密度,达
Diesel engine using direct air cooling air cooling technology in high-power diesel locomotive has been more reported that it not only improves the operating performance of diesel locomotives and improve the reliability of the use of the main components of the air-cooled diesel locomotive air-to- Air cooler and air-cooled fan design, the main parameters of the choice of analysis for the design of air-cooled devices for reference. (A) air - air-cooled device profile and composition 1. Air - air-cooled device Introduction At present, locomotive diesel engine intake are varying degrees of supercharging, after the pressurized air are intermediate cooling into the diesel engine to improve the average intake Effective pressure and air intake density up to
