生产中用管道输送流动介质(气体、液体)时,由于种种原因,介质在管道内形成揣流而产生管道噪声。此类噪声随管道的分布而传播,影响范围较大,应重视予以控制。 管道噪声的控制措施一般较复杂,且往往因生产工艺和条件的限制而增加了控制难度。最简易的方法是在管道外壁敷设隔声层,达到降噪的目的。 Pipeline production in the production of mobile media (gas, liquid), due to various reasons, the medium formed in the pipeline hides and produces pipe noise. Such noise spread with the distribution of the pipeline, the impact of a larger range, attention should be given to control. Pipeline noise control measures are generally more complicated, and often due to the constraints of production technology and conditions to increase the control difficulty. The easiest way is to lay the sound insulation layer on the outer wall of the pipeline to achieve the purpose of noise reduction.
