柴油机正常运转时具有一定规律性、均匀及轻微的噪声。当柴油机遇到安装、调整不当,保养、维修不及时,修理质量低劣,使用操作不当,零部件磨损,配合间隙增大或零部件突然损坏等情况时,就会出现异常机械响声。不同零件、不同部位和不同工况,其声源发出的异响在声音和频率等方面有所区别。本文介绍了各种机械异响的声响特征,分析了其产生的原因,提出了检查和排除的方法。
Diesel engine has a certain regularity during normal operation, uniform and slight noise. When the diesel engine encountered installation, improper adjustment, maintenance, repair is not timely, poor quality of repair, improper use of improper operation, parts wear and tear, with increased clearance or parts suddenly damaged, etc., there will be abnormal mechanical noise. Different parts, different parts and different working conditions, the noise emitted by the sound source in terms of sound and frequency are different. This paper introduces the sound characteristics of various mechanical abnormalities, analyzes the reasons for the occurrence of mechanical abnormalities, and puts forward the inspection and elimination methods.
