内燃机车冷却系统的工作状态是否良好,对内燃机功率的正常发挥和机车的安全运行有直接的影响。冷却系统工作状态恶化的主要因素是冷却系统受热面上结生水垢和金属材料的腐蚀。目前,我国内燃机车上所使用的冷却液是采用离子交换水加红矾,它对钢、铁、铝等仍有较严重的腐蚀,同时还需要有较大的水处理 Whether the working condition of the diesel locomotive cooling system is good or not has a direct impact on the normal performance of the internal combustion engine and the safe operation of the locomotive. Cooling system working condition deterioration is the main factor cooling system heating surface scaling and corrosion of metal materials. At present, the coolant used in diesel locomotives in China uses ion exchange water plus red alum, which still has more serious corrosion on steel, iron and aluminum, and also needs larger water treatment
