Description
Technical Field
The utility model relates to a silencer subassembly technical field specifically is a high strength silencer screen panel.
Background
The silencer is also called a silencer, is widely applied in modern industry, particularly after a series of national energy-saving and noise-reducing standards are released, enterprises pay attention to the development and operation of various energy-saving, emission-reducing, noise-reducing and noise-reducing projects, and the silencer is a special device for preventing noise transmission and allowing airflow to pass and can effectively block the sound transmission and allow the airflow to pass and control the noise. The method is widely applied to the fields and industries of electric power, mines, metallurgy, energy, petroleum, chemical engineering, textile, medicine, food, building materials, coal, municipal engineering and the like, and is deeply welcomed by the majority of users. The silencing principle of the silencer is that the proper combination of the cavity and the pipe is utilized to achieve two functions for silencing. One is to use the abrupt change of the pipe section (i.e. the change of the acoustic reactance) to reflect the sound wave propagating along the pipe back to the sound source direction, so that the sound energy is reflected back to the original place. Secondly, the reflection of a plurality of interfaces is utilized to make the original first forward-transmitted sound wave return to the original point and return to the forward transmission again, the point is merged with the second forward-transmitted sound wave which is not reflected, the two waves are equal in amplitude and differ by an odd multiple of 180 degrees in phase, and therefore the two waves interfere with each other and are offset. A silencer ((Muffler)) is a device that prevents sound from propagating while allowing airflow to pass through, and is an important measure to eliminate aerodynamic noise. The silencer is a device for reducing noise, which is arranged on an airflow channel of air power equipment (such as a blower, an air compressor, a boiler exhaust port, a generator, a water pump and other equipment with high noise at an exhaust port) or in an air inlet and exhaust system.
