Muffler muffler weight impedance chip impedance muffler muffler Lu Sheng air conditioning ..

WBX-type muffler is a perforated plate as a member, is a pure metal muffler structure. Muffler with stable performance, small pressure loss, low noise airflow regeneration, resistant to moisture, high temperature resistance, air scour and so on. The muffler is suitable for ventilation silencers at high temperatures, high speed, wet conditions, especially for a clean environment, such as food, medicine and various halls of ventilation and air conditioning systems mufflers. Details impedance muffler by resistive structure and resistant structure constituted in accordance with certain combinations. Resistive muffler is the use of porous sound-absorbing materials to reduce noise. The sound-absorbing material is fixed to the inner wall of the gas flow passages arranged in a certain way or in the pipeline, constitute the resistive silencer. When sound waves enter the resistive muffler, part of the acoustic energy is converted into heat friction dissipated in the pores of the porous material, the sound waves passing through the muffler weakening. Resistive muffler as if the pure resistance on the electrical circuit, sound-absorbing material similar to resistance. Therefore, people put this silencer called resistive muffler. Resistive muffler muffler effect of high-frequency, low frequency silencing effect is poor.
