一、Structure form
1、TYF muffler is the principle of impedance compound muffler, which USES sound absorption material drop into heat energy, use channel interface mutations and resonant cavity to make certain frequency or part of the reflection spectrum of noise or within the cavity resonance occurs, make this part of the noise can't spread. TYF type silencer by using superfine glass wool, absorption column tube ventilation and cross piece to highlight the principle of impedance compound muffler.
2、TYF muffler is a total of 11 kinds of specifications, each kind of specification is divided into type I and II in two forms. Type I to end with a flange, the other end with a waterproof cap. Type II both ends with flange, can be directly used in the pipe,
3、Muffler, when installation should be column section is located in the upstream wind resistance property。
二、USES: mainly used for 9 -, 9-19 and 26 machine supporting the acoustical noise reduction of high-pressure centrifugal fan, also applies to 9 -, 9-19 and 26 type high pressure centrifugal fan muffler selection, can be directly used in closed room air inlet and outlet pipe.
(1)Apply to the air volume 2000-50000 m3/ h, (2) apply to the temperature of120 ° C.
