消声器产品的用途及消声器的特点:
消声器是一种通用机械设备，其使用范围很广，电力、矿山、机械、冶金、化工等各行业的生产均离不开消声器。消声器在运转中产生的噪声常常成为影响工人健康和干扰环境的祸源。
该消声器系列产品为阻抗声流型。
消声器就是频率高于20kHz、超出人们耳朵辨别能力并且穿透性很强的声波。消声器的应用有很多，比如用消声器的反射来测量距离，利用大功率超声的振动来清除附着在锅炉上面的水垢，利用高能超声做成消声器来消灭、击碎人体内，而利用超声的反射等效应和穿透力强、能够直线传播等的特性来进行检测也是其中一个很大的应用领域。
消声器的检测应用主要包括在工业上对各种材料的检测和在医疗上对人体的检测诊断，通过它人们可以探测出金属等工业材料中缺陷，可以检测出人们身体的软组织、血流等是否正常。
那么人们是怎么样利用超声来进行检测消声器的呢？现在通常是对被测物体发射超声，然后利用其反射、多普勒效应、透射等来获取被测物体内部的信息并经过处理形成图像。其中多普勒效应法是利用消声器在遇到运动的物体时发生的多普勒频移效应来得出该物体的运动方向和速度等特性；透射法则是通过分析消声器穿透过被测物体之后的变化而得出物体的内部特性的，其应用目前还处于研制阶段；这里主要介绍的是目前应用最多的通过反射法来获取物体内部特性信息的方法。
消声器故障的主要原因是设计、制造、选择或使用不当造成的。这些故障如不及时消除，就会影响消声器的功效和寿命，甚至不能起到安全保护作用。常见的故障及处理方法如下：
（1）泄漏。
（2）到规定压力时不开启。
（3）不到规定压力开启。
（4）排气后压力继续上升。
（5）排放后消声器不回座。
（6）消声器频跳或振动。
想了解贵公司更多的产品欢迎您拨打：13861426778（孙经理）有关更多产品信息参数请访问：http://www.smdlfj.com http://www.lyg095.com http://www.sm0818.com http://lyg0818.com The noise reduction effect of the above-mentioned mufflers can meet the requirements of 《Noise health standards of industrial enterprises》，which have been extensively used in China .
5.Fan silencer(GF-type)
Our company has produced series of fan silencers for noise reduction to use to harness fan on the aerodynamic noise caused by the environment.
We supply variety of axial and centrifugal fans for Inlet/Outlet noise elimination
Fan is a universal mechanical equipment, which is widely used in electricity, mining, machinery, metallurgy, chemical industry, etc.The noise that fan produces in operation often becomes the misfortune source of the health of the workers and the environmental interference.Especially in the living area adjacent to the fan, the aerodynamic noise by radiation from the air intake and air outlet is even more a major factor for environment pollution,which has been the one of the main targets China industrial departments control noise pollution.
Industrial fan is a continuous operation equipment .International Organization for Standardization(ISO) has stipulated that the noise of the fan wouldn't exceed 90dB which is the same with the new standard of China. This is also the basis of industrial enterprises whose continuous noise reaches the standard. However, if we don't take noise reduction measures,when the fan passes in and out of the tuyere , the noise volume radiates to the environment can up to 110~120dB.
Fan silencer products are Acoustic impedance flow pattern..In order to determine how much muffler volume is needed for the design of the acoustic absorption slices structure and fluid channel,this factory basis on the frequency spectrum properties by the actual test of the noise sources at the scene when all kinds fans of power plant are in operation, .Meanwhile,we adopt the narrow rectangular channel of the finishes with a larger sound-absorbing material to enhance the absorption.We know , when the noise source of the fan is at the maximum level,the value of the spectrum is often more than one.For the different frequency bands,its requirement for the muffler volume is also different.To reduce noise,we adopt resistance structure for the high-frequency and mid-frequency noise and anti-structure for the mid-frequency and low-frequency noise..At the same time,in order to achieve the desired muffler effect,this product adopt low-frequency and high-frequency noise reduction areas in the resistance channel for maximizing the width of the noise reduction band .
If installed according to require, the muffler volume will not exceed 85-90 dB. The mufflers described in the manual are applied for kinds of axial and centrifugal fans .In addition,our company has produced utility exhaust mufflers series for gas turbines, Roots blower, air compressor and diesel etc.Welcome customers to consult and order.

"G"means the the first letter of Chinese Phonetic Alphabet of "Guolu"(Boiler)
"F"means the the first letter of Chinese Phonetic Alphabet of Fengji(Fan)
"10"meansFans of the average amount of air volume for the fan nameplate.
Example6:TC-38-30 Series
Soot-blowing pipe muffler.Design Pressure :3.8MPa Displacement:30T/H
4、Ordering and selection tips
The muffler is well-designed according to the steam emission targets and emissions requirements of users ,only the products are in accordance with the emissions targets steam parameters and the displacement can the ideal elimination effect achieve.So, when ordering the muffler the following information must be offered:
① Turbine models, capacity boiler, steam pressure and temperature
② The use of targets
③ Displacement:T/H
④ The the original diameter, thickness of exhaust pipe
⑤ If requiring our company to install , the original installation plans of the exhaust pipe should be provided.
Installation Notice
1、Muffler should be installed perpendicular to the plant top, Show in Chart3: with steel brackets to fix muffler blocks and plant.
2、In order to increase wind resistance, silencer-bearing support has been used. So, in front of the muffler exhaust pipe, it should have a segment of expansion bend to absorb heat expansion.If the original exhaust pipes have been installed with the hydrophobic plate in the vertical direction , the expansion bend needn't be installed.
3、The reduced water pipes or drainage hole has been designed at the bottom of muffler body.the orifice should be examined to ensure that unobstructed.
4、If exhaust pipe through the plant platform hole, a rain-cover should be made up by thin steel plate.
5、For security doors, in principle, a security door which has single-seat and two-seater is distributed a muffler. For the two-seater, the exhaust pipe can be fixed into a main pipe when installed.However,for the two-seater door with a large exhaust volume , two mufflers can be installed.
6、The mufflers for the deaerator and steam jet aspirator with the little exhaust volume should be designed as a tubular shape ,so the installation will be more convenient.Installed as shown in Chart4.Muffler installed along the vertical direction of the wall/column of the main plant.The outfall of muffler should towards to the direction of the roof. It should be noted that the muffler factory has been fixed stent. If it used a sliding installed stent, the fixed stent can not to be used
