山东装载机的噪声分析
山东装载机在公路、铁路以及建筑工程上使用的比较多,在使用装载机的过程中是会发生很多噪声,对于这些噪声又是怎么形成的呢?下面永保机械的专家给大家仔细总结一下。
第一就是山东装载机发动机的噪声是装载机噪音的最大来源,在正常情况下,柴油机的噪声是会随着转速的增加而上升的。
The first is that the noise of the engine of the Shandong loader is the largest source of the noise of the loader. Under normal circumstances, the noise of the diesel engine will increase with the increase of the speed.
第二就是山东装载机气体噪声,排气噪声产生的机理就是在排气阀处,气体的流动是不稳定的,一般会以压力波动的方式,传到排气系统的出口,在尾管出产生辐射噪声。
The second is Shandong loader gas noise mechanism of exhaust noise generated is in the exhaust valve, the gas flow is not stable, generally by the pressure fluctuation of the way to the exhaust system of export, in the tail tube radiation noise.
第三就是山东装载机燃烧噪声,柴油机工作的燃烧室在短时间内产生高温高压紧燃烧,急速的释放热量,这种急剧的压力是会引起发动机结构的振动产生噪声。
The third is Shandong loader combustion noise of diesel engine, the combustion chamber to generate high pressure tight combustion in a short period of time, the release of heat rapidly, the rapid pressure will produce noise caused by vibration of the engine structure.
