完善检修工艺 解决柴油机超压故障

Improve Maintenance Technique to Overcome the Over-pressure in Diesel Engine

通过对机车柴油机超压现象的原因分析,得出导致柴油机超压的原因有:活塞顶裂纹、活塞气环折断、气缸套磨损。自制新工装,制定并完善检修工艺,准确检测出故障部位,解决了机车柴油机超压的故障。

The cause of over-pressure in Diesel Engine includes fracture on piston, fracture of piston rings and cylinder wear. The maintenance technique was improved to determine the obstale and to overcome the over-pressure problem.
