本文简单介绍了ND_5型机车柴油机动力组结构特点,重点介绍了ND_5型0108号机车柴油机左七,右七两个动力组故障破损情况。分析了故障产生的原因是气缸盖裂纹漏水造成的。文中还呼吁有关部门加强对轮乘制机车的保养检查工作,合理制定ND_5型机车牵引吨位,防止强化使用ND_5型机车柴油机,使其故障能早期发现,早期预防。
This paper briefly introduces the structural characteristics of ND5 locomotive diesel engine dynamic group, and focuses on the fault damage of the left seven and right seven diesel locomotives of the ND_5 0108 locomotive. Analysis of the cause of the failure is caused by the cylinder head cracks leaks. The article also called for the relevant departments to strengthen the inspection and maintenance of wheel-set locomotive maintenance and reasonable development of ND_5 locomotive traction tonnage to prevent the intensified use of ND_5 locomotive diesel engine so that the failure can be detected early and early prevention.
