問:為什么你們廠生產(chǎn)的羅茨風(fēng)機(jī)要標(biāo)配消音器啊?

答:之所以標(biāo)配消音器,主要是因?yàn)?span style="color: rgb(255, 0, 0);">羅茨風(fēng)機(jī)消音器的作用!消音器是控制空氣動力性噪聲外部傳播的有效設(shè)備,在內(nèi)部進(jìn)行聲學(xué)處理可以大大減少噪聲的產(chǎn)生和傳播,不會影響氣流的通過。安裝消音器后,設(shè)備的噪聲量應(yīng)達(dá)到20-40dB(A),主觀感覺響度相應(yīng)減少50-90%的效果。
羅茨風(fēng)機(jī)消音器的類型:
1.電阻式消音器具有吸收中高頻聲、加工制造簡單等特點(diǎn),一般用于空調(diào)風(fēng)機(jī)、壓縮機(jī)、燃?xì)廨啓C(jī)、鼓風(fēng)機(jī)等風(fēng)機(jī)類消聲。
2.抗性消音器具有針對性強(qiáng)、對中低頻吸聲效果好、不使用吸聲材料等特點(diǎn)。通常只能用于小型管道排氣消聲,如汽車、船舶、柴油機(jī)等的排氣消聲。
3、阻抗型消音器具有噪音頻帶寬、使用安全等特點(diǎn)。主要用于音級高但頻率低的中頻寬帶噪音的消聲。汽輪機(jī)、除氧器、擴(kuò)容器、小排量的安全閥排汽等。
4、小孔消聲器具有低中頻寬帶消聲性能,小孔直徑增加吸聲系數(shù),低孔間隙增加吸聲帶的寬度,孔板深度可以改變共振吸聲峰的位置。小孔型消音器具有設(shè)計嚴(yán)格、吸收頻帶寬、電阻小、耐高溫、壽命長等優(yōu)點(diǎn)。一般用于鍋爐、壓縮機(jī)等高壓設(shè)備的排氣放空。
5.抗噴阻復(fù)合消音器具有消音頻帶寬、使用范圍廣、消音量大、耐高溫高壓、不怕水汽及油霧的優(yōu)點(diǎn)。基于我國著名聲學(xué)家馬大猷的小孔噴注消聲理論研制成功,目前是我國**結(jié)構(gòu)的排氣消音器,各電站普遍選擇使用。
6、通孔阻散型消音器具有排氣暢、耐高溫、抗干擾等優(yōu)點(diǎn)。通常用于安全閥、排氣閥、汽輪機(jī)和吹管等排氣消聲。
友情提示:我們廠生產(chǎn)銷售的羅茨風(fēng)機(jī)不僅可以標(biāo)配消音器!而且可以跟您的需求定制隔音罩哦!

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 automobile, 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!
