1, the company designed and manufactured muffler used to reduce the fan, the export of aerodynamic noise.
2, muffler installation, from the muffler into the (mouth) 1.5 meters to 2 meters should be no obstruction, and pay attention to avoid other noise sources, so as not to affect the normal use of muffler effect.
3, muffler and fan connection flange diameter is inconsistent, can be coupled with the transition tube, but the equivalent angle should not be greater than 30 °. Connect the flange should avoid rigid connection, and pay attention to seal, to prevent leakage, leakage.
4, muffler can be installed according to actual needs in any position in the space, but should pay attention to the support of the muffler. Muffler can not withstand external weight.
5, muffler should be installed in the air flow channel smooth section, in particular, to avoid installation in the pipe elbow.
6, through the muffler gas dust content should be less than 100 mg / standard cubic meters, or to install the air filter, so as not to affect the use of results.
7, through the silencer media is not allowed to contain water mist, oil mist and corrosive gases. The medium temperature should not be less than 150 ℃.
8, muffler used after a period of time. If the fouling effect is reduced, can only use dry brush to remove dust, and can not rinse with water.
9, muffler in the transport and to be installed before to take moisture, anti-fouling measures, so as not to affect the normal use of the future effect.
10, to meet the above conditions of use, the life of the muffler is usually up to 8-10 years.
F type muffler
Muffler is because the domestic more mature resistance composite muffler, which is mainly used to reduce the various high-pressure centrifugal fan import and export of aerodynamic noise, especially for the fan industry 9-19,9-26 and other models of high-pressure centrifugal fan The
F-type muffler is divided into A, B two forms. A-type ends are flanges, can be used in series in the pipeline, B-type one end of the flange, the other end of the rain suction hood. Can be used for the use of exhaust.
F-type muffler using air flow 2000-66000m3 / h, the use of temperature below 150 ℃, muffler up to 20-25dB (A), the resistance loss is less than 300mmH2O (294pa).
