罗茨风机在使用的过程中产生噪音是难免的，那么对于这些噪音来说我们应该如何处理呢？罗茨风机小编带您了解一下。
1、Installation of muffler
In general, the aerodynamic noise radiated from the fan air intake and exhaust ports is 10-20dB(A) higher than the noise radiated from other parts, therefore, when controlling the fan noise, the first thing to do is to install appropriate mufflers on the air intake and exhaust official channels.
The muffler is used on the fan, at present, domestic and foreign countries tend to use the resistive muffler, and the muffler with larger volume and narrower muffling channel has been seldom used, of course, the muffler selection, design and installation should be carried out according to the actual situation.
2. Establishment of acoustic enclosures
The use of acoustic enclosure measures, that is, the entire fan unit with a closed acoustic enclosure surrounded. The technical key is to use what kind of cooling measures to ensure the normal operation of the fan. At present, both at home and abroad to use air-cooled method for **** common. The main forms of cooling are: self-fan ventilation cooling method, negative pressure suction cooling method, hood air circulation ventilation cooling method and external mechanical ventilation cooling method.
3. Modification of the fan room
如果风机组有专门的风机房，则可以结合现场情况，采取将已有的风机房改造成隔声间的方法。即把罗茨风机封闭在风机房内使其噪声传不出去。主要技术措施是采用隔声门、隔声窗、隔声屏障和墙壁隔声，应用合适的吸声材料等。
4, pipe wrapping in order to attenuate the noise radiated from the fan duct, you can rotate the pipe wrapping, compartment noise from the path of dissemination.
5, vibration isolation comprehensive consideration of safety, stability and ease of maintenance and other factors, the design and selection of appropriate vibration isolators, in order to eliminate the rigid connection between the machine and the unit, so as to achieve the purpose of reducing solid vibration noise. Can also dig anti-vibration ditch to replace the foundation vibration isolation, can achieve certain results.
