答：之所以标配消音器，主要是因为罗茨丝瓜视频黄色下载消音器的作用!消音器是控制空气动力性噪声外部传播的有效设备，在内部进行声学处理可以大大减少噪声的产生和传播，不会影响气流的通过。安装消音器后，设备的噪声量应达到20-40dB(A)，主观感觉响度相应减少50-90%的效果。

　　罗茨丝瓜视频黄色下载消音器的类型：

　　1.电阻式消音器具有吸收中高频声、加工制造简单等特点，一般用于空调丝瓜视频黄色下载、压缩机、燃气轮机、鼓丝瓜视频黄色下载等丝瓜视频黄色下载类消声。

　　2.抗性消音器具有针对性强、对中低频吸声效果好、不使用吸声材料等特点。通常只能用于小型管道排气消声，如汽车、船舶、柴油机等的排气消声。

　　3、阻抗型消音器具有噪音频带宽、使用安全等特点。主要用于音级高但频率低的中频宽带噪音的消声。汽轮机、除氧器、扩容器、小排量的安全阀排汽等。

　　4、小孔消声器具有低中频宽带消声性能，小孔直径增加吸声系数，低孔间隙增加吸声带的宽度，孔板深度可以改变共振吸声峰的位置。小孔型消音器具有设计严格、吸收频带宽、电阻小、耐高温、寿命长等优点。一般用于锅炉、压缩机等高压设备的排气放空。

　　5.抗喷阻复合消音器具有消音频带宽、使用范围广、消音量大、耐高温高压、不怕水汽及油雾的优点。基于我国著名声学家马大猷的小孔喷注消声理论研制成功，目前是我国**结构的排气消音器，各电站普遍选择使用。

　　6、通孔阻散型消音器具有排气畅、耐高温、抗干扰等优点。通常用于安全阀、排气阀、汽轮机和吹管等排气消声。

　　A: the standard silencer is mainly due to the function of Roots blower silencer! Muffler is an effective equipment to control the external transmission of aerodynamic noise. Acoustic treatment inside can greatly reduce the generation and transmission of noise and will not affect the passage of air flow. After installing the silencer, the noise level of the equipment shall reach 20-40db (a), and the subjective perceived loudness shall be reduced by 50-90%.

　　Type of Roots blower silencer:

　　1. Resistance silencer has the characteristics of absorbing medium and high frequency sound and simple processing and manufacturing. It is generally used for noise elimination of air conditioning fans, compressors, gas turbines, blowers and other fans.

　　2. The resistant silencer has the characteristics of strong pertinence, good sound absorption effect for medium and low frequency, and no sound-absorbing materials. Generally, it can only be used for exhaust silencing of small pipelines, such as automobiles, ship, diesel engine, etc.

　　3. The impedance muffler has the characteristics of noise audio bandwidth, safe use and so on. It is mainly used for silencing if broadband noise with high sound level but low frequency. Steam turbine, deaerator, flash tank, safety valve with small displacement, etc.

　　4. The small hole muffler has the performance of low medium frequency and wide-band silencing. The small hole diameter increases the sound absorption coefficient, the low hole gap increases the width of the sound absorption band, and the depth of the orifice plate can change the position of the resonance sound absorption peak. The small hole silencer has the advantages of strict design, wide absorption frequency band, low resistance, high temperature resistance, long service life and so on. It is generally used for exhaust and venting of boilers, compressors and other high-pressure equipment.

　　5. The anti blowout composite silencer has the advantages of audio frequency elimination bandwidth, wide application range, large silencing volume, high temperature and high pressure resistance, and is not afraid of water vapor and oil mist. Based on the small hole injection silencing theory of Ma Dayou, a famous Chinese acoustician, it has been successfully developed. At present, it is the exhaust muffler with the latest structure in China, which is widely used in all power stations.

　　6. The through-hole dissipative muffler has the advantages of smooth exhaust, high temperature resistance, anti-interference and so on. It is usually used for exhaust silencing of safety valves, exhaust valves, steam turbines and blowpipes.

　　Friendly tips: the roots blower produced and sold by our factory can not only be equipped with silencer as standard! And you can customize the sound insulation cover according to your needs!
