Detailed Product Description: | Nanjing diesel generator set | muffler principle - resistive muffler resistive muffler (Industrial type muffler) is the use of porous sound-absorbing material, in a manner arranged in the pipe, when the air flow through the resistive muffler, the sound waves will cause sound-absorbing material voids the air and the small fiber vibration. Due to friction and viscous resistance, sound energy into heat energy absorbed, and thus play a role in silencer. Resistive Resistive muffler muffler is the use of sound waves in the sound-absorbing material or a porous sound absorbing structure in the spread, due to friction and the sound energy into heat and dissipated, so that the noise propagation along the pipeline and decay with distance, so as to achieve the purpose Muffler muffler. Absorbing materials commonly used in glass fiber yarn, low carbon steel wire, felt or the like. Such high-frequency noise muffler right muffler has a good effect, and low frequency noise elimination performance is poor. Resistive muffler is to absorb acoustic energy muffler. Using a wide range, at an intermediate frequency or high frequency noise attenuation and for the case of small flow resistance may be used. Depending on requirements, can take different forms of sound-absorbing materials and structures. For usual air conditioner, can be used in the pipe wall lining layer of glass fiber structure, the thickness of about 2.5cm. Large wind tunnel or jet engine test between the exhaust port design complexity, can be installed in the pipeline parallel plates stacked absorbers or spatial array of acoustic cylinder and so on.
