High Temperature And High Pressure Muffler

Resistant muffler structure: Usually contains components such as expansion chambers and resonance cavities. By changing the cross - sectional area of the air flow channel, phenomena such as reflection and interference of sound waves occur during the propagation process, thus consuming sound energy. For example, when sound waves enter the expansion chamber from a pipe with a smaller cross - sectional area, the sound waves will be reflected, and part of the sound energy is reflected back, reducing the sound energy propagating forward. Resistive muffler structure: It is filled with high - temperature - resistant sound - absorbing materials inside, such as ceramic fiber, glass wool, etc. When sound waves pass through, they interact with the pores of the sound - absorbing materials, and the sound energy is converted into heat energy and absorbed. Some mufflers also have multiple layers of throttle orifice plates to reduce the gas pressure. At the same time, they cooperate with the resistive muffler structure to further enhance the muffling effect. Composite muffler structure: Combines the resistant and resistive muffler structures to form a resistance - jet - absorption composite muffler. This type of muffler has the advantages of both, has a wide muffling frequency band, can effectively reduce noise within a relatively wide frequency range, and can withstand high - temperature and high - pressure air flow environments.
