山東裝載機在公路、鐵路以及建筑工程上使用的比較多，在使用裝載機的過(guò)程中是會(huì )發(fā)生很多噪聲，對于這些噪聲又是怎么形成的呢？下面永保機械的專(zhuān)家給大家仔細總結一下。

第一就是山東裝載機發(fā)動(dòng)機的噪聲是裝載機噪音的最大來(lái)源，在正常情況下，柴油機的噪聲是會(huì )隨著(zhù)轉速的增加而上升的。
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. 

第二就是山東裝載機氣體噪聲，排氣噪聲產(chǎn)生的機理就是在排氣閥處，氣體的流動(dòng)是不穩定的，一般會(huì )以壓力波動(dòng)的方式，傳到排氣系統的出口，在尾管出產(chǎn)生輻射噪聲。
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. 

第三就是山東裝載機燃燒噪聲，柴油機工作的燃燒室在短時(shí)間內產(chǎn)生高溫高壓緊燃燒，急速的釋放熱量，這種急劇的壓力是會(huì )引起發(fā)動(dòng)機結構的振動(dòng)產(chǎn)生噪聲。
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.
