柴油机某部位出现故障时,常常会伴随机件运转发出异常响声。柴油机在运转状态下,其“异响”多样、复杂,难以分辨,给机械维修人员常带来许多麻烦,从而延长维修时间。但只要在平时的维修过程中注意总结、掌握其规律性,就能辨认出因磨损而使间隙增大所发出的噪声:如小零件相撞击,则音调高、量弱、清脆、尖锐和 When a part of a diesel engine fails, it often emits an abnormal noise when the part runs. Diesel engine in operation, its “abnormal sound” diverse, complex and difficult to distinguish, to the mechanical maintenance staff often bring a lot of trouble, thereby extending the repair time. But as long as the usual maintenance process to pay attention to summarize, to grasp the regularity, we can identify due to wear and tear caused by the increased gap noise: such as small parts collide, the pitch is high, the amount of weak, crisp, sharp and
