Origin:
The function of the discharge muffler from China manufacturer is to reduce the exhaust noise by gradually reducing the exhaust pressure and attenuating the pulsation of the exhaust pressure.
The working principle of the discharge muffler from China manufacturer:
The muffler is made of aluminized steel plate or stainless steel plate. Usually the muffler consists of a resonance chamber, an expansion chamber and a set of porous tubes. Some mufflers are filled with heat-resistant sound-absorbing materials, most of which are glass fibers or asbestos. The exhaust gas flows into the expansion chamber and the resonance chamber through the porous pipe. During the process, the exhaust gas continuously changes the flow direction, gradually reduces and attenuates its pressure and pressure pulsation, consumes its energy, and finally reduces the exhaust noise.

According to the principle of interference, the discharge muffler from China manufacturer has two basic noise reduction methods: absorption type and reflection type. The absorption muffler reduces the energy of the exhaust gas through friction on sound-absorbing materials such as glass fiber, steel fiber, asbestos; the reflection muffler has multiple harmonic cavities connected in series, and the harmonic cavities are connected with porous reflection tubes of different lengths. Multiple reflections, collisions, expansion and cooling in the harmonic cavity to reduce its pressure, vibration and energy.
