centrifugal fan silencer

- Aug 31, 2018 -

The centrifugal fan silencer (sound) is developed according to the sound-absorbing principle of the sound-damping piece. The muffler has excellent acoustic performance and good aerodynamic performance; the structure is reasonable and easy to install, and it is a large-winding and resistive honeycomb muffler. The resistant section uses a multi-compartment resistant plastic straight tube channel and a cross-shaped sound absorbing sheet to ensure sufficient noise reduction over a wide frequency range. The structure of the muffler is composed of a plurality of parallel unit silencer tubes, and the sound absorbing tube is filled with a porous sound absorbing material to generate a radiated sound for reducing the vibration of the shell wall by the airflow, and a reinforcing rib is arranged on the outer casing.

The new high-efficiency anti-spray resistor series muffler equipment is widely used in power generation, chemical, metallurgy, textile and other industrial factories and mines for various types of boilers, steam turbine exhaust; fans; safety gates and other equipment for noise reduction. This series of muffler is developed according to the anti-fogging principle of anti-, spray and resistance. It has many advantages such as large noise reduction, small volume, light weight, convenient installation and no maintenance. The centrifugal ventilator muffler is developed according to the principle of sound absorbing silencer. The resistant section adopts multi-chamber resistant rubber straight pipe passage and cross-shaped sound absorbing film to ensure sufficient noise reduction in a wide frequency range. . The muffler structure consists of a number of parallel unit silencer arrangements.
