Study on Advanced Maintenance Scheme of the Compound Cooler for Electric Locomotive

介绍电力机车复合冷却器工作原理、分类与结构特点,分析、研究复合冷却器的应用情况和存在的主要问题,提出复合冷却器高级修技术方案,并在检修作业中实施。实际检修效果表明,采用电力机车复合冷却器高级修方案检修复合冷却器,不仅能有效排查复合冷却器4类典型故障的质量风险点,还可提高复合冷却器检修质量,延长复合冷却器寿命,降低检修成本。

The paper introduces the working principle,classification and structural characteristics of the composite cooler for electric locomotive,analyzes and studies the application and main problems of the composite cooler,and puts forward the advanced maintenance technical scheme of the composite cooler,which is implemented in the main⁃tenance work.The actual maintenance results show that using the advanced maintenance scheme of the composite cooler for electric locomotive to repair the composite cooler can not only effectively check the quality risk points of the four typical faults of the composite cooler,but also improve the maintenance quality of the composite cooler,extend the life of the composite cooler and reduce the maintenance cost.
