矿用柴油机自身诊断系统(OBD)主要局限于有传感器的部件和系统中,多数故障无法用OBD判断,且许多故障属于“软故障”和非典型故障。矿用设备外形高大,柴油机高强化、负荷重,运转时噪声大,超期服役导致一些部件和系统内污垢沉积严重,为故障诊断增添诸多困难。因此,笔者就“传统法”对柴油机进行故障诊断谈几点看法。1掌握柴油机基本知识和典型故障的特点矿用柴油机结构复杂,新机型不断涌现,必须不断更新知识,钻研相关柴油机构造、使用维修手册 The OBD of mining diesel engines is mainly confined to the parts and systems with sensors. Most of the faults can not be judged by OBD, and many faults belong to “soft fault” and non-typical fault. Mining equipment tall appearance, high-strength diesel engine, heavy load, noise during operation, extended service caused some of the components and systems within the serious dirt deposition, fault diagnosis to add a lot of difficulties. Therefore, the author on the “traditional law ” on the diesel engine troubleshooting talk about several points. 1 mastered the basic knowledge of diesel engine and the typical fault characteristics Mining diesel engine complex structure, new models continue to emerge, we must continue to update their knowledge, study related diesel engine structure, the use of maintenance manual
