风机他的噪声环保又是体现的，噪声他包括的内容也有许多，像是气氛动力性噪声、结构噪声、机械噪声等等。这个气氛动力性噪声他其实是一种非稳定性气体的活动。当气体和气体或许气体和物体他们之间有感动那么会有噪声。他是由旋转噪声和涡流噪声一起组成的。风机他的气氛动力性噪声能够把噪声还有涡流噪声让他们进行混淆，这个机械噪声主要还是经过风力风机他的机壳来向四周进行辐射，电机他的噪声是比较小的。
The noise and environmental protection of a fan are also reflected, and the noise also includes many aspects, such as atmospheric dynamic noise, structural noise, mechanical noise, and so on. This atmospheric dynamic noise is actually an activity of an unstable gas. When there is a connection between gas and object, there will be noise. He is composed of rotating noise and eddy current noise together. The dynamic noise of the wind turbine's atmosphere can confuse the noise and eddy current noise, and this mechanical noise mainly radiates around the wind turbine's casing, while the noise of the motor is relatively small.
咱们刚刚装置的离心风机他的风量常常是比较大的，这样等到风机在装置好以后正式的开始运行后，他在进行操作的时分会有大小的改动，太大或许太小咱们都可以用相应的方法来进行解决，像是把风机的流量进行调整，把管网的阻力流量进行调整等等。要是叶片通过以后，气体他的压力快速的进行起伏，那么叶片他会连续的进行改动，会有许多的压力脉动呈现，会有很大的气流不匀称性，进而到处都有噪声。
The air volume of the centrifugal fan we just installed is usually relatively large, so when the fan starts to run formally after installation, there will be major and minor changes in its operation. If it is too large or too small, we can use corresponding methods to solve the problem, such as adjusting the flow of the fan and the resistance flow of the pipe network. If the pressure of the gas fluctuates rapidly after the blade passes through, the blade will undergo continuous modifications, resulting in many pressure fluctuations and significant airflow asymmetry, resulting in noise everywhere.
