装载机排气为何会产生噪声呢?

一般来说，装载机产生的排气噪声，主要是排气系统辐射出来的总噪声，它包括三个方面：一个是管壁的辐射噪声，一个是消音器壁的辐射噪声，还有一种是尾管出口的启动辐射噪声。
In general, the exhaust noise Shandong loader, is mainly the total noise radiated from the exhaust system, it includes three aspects: one is the radiation noise of the pipe wall, a radiation noise silencer wall, there is a start

radiation noise of tail pipe outlet.  

装载机产生噪声的原因，是在装载机柴油机工作过程中，在排气阀的地方，气体流动不稳定，气流以压力波动的方式传到了排气系统的出口，在尾管出口处，连速度波动产生了不规则噪声，我们也可以简单的理解是排气系统内气流不稳定引发了排气噪声。
Shandong loader noise, is in the loader working process of diesel engine, the exhaust valve in place, gas flow instability, the airflow to the pressure fluctuation of the way to the exhaust system outlet pipe outlet in the tail, even the speed fluctuation produced irregular noise, we can simply understand air exhaust system instability caused exhaust noise.  

装载机产生轻微的噪声是正常的，如果一旦产生产生异常的噪声，必须停机检查，必要时要找专业维修师傅排查原因。
Shandong loader to produce a slight noise is normal, if there is an abnormal noise, it must be shut down, if necessary, to find a professional maintenance of the cause of the investigation.
