Description:
Blower Muffler Application and Characteristics of Blower Muffler: Blower is a general machine, which applied in a wide range such as electric power,
mine, metallurgy, and chemistry industry. However, the noise that running fans
produce is a harmful source that always influences workers' health and environment,
and furthermore, aerodynamic noise that fan inlet and outlet radiate is a key
factor of environmental pollution and is social effects of pollution.
Industrial fans are continual equipment. The standard of noise for this type of equipment
that ISO stipulates is less than or equal to 90 dB, the same as Chinese
new standard, which is basis for industrial enterprises. However, the noise that
fan inlet and outlet produce would reach from 110 to 120 dB which greatly exceeds
the standard if no taking anechoic measures.
The series of mufflers belong to block acoustic flow type. It is a main basis for
designing configuration of sound absorption flake and wind tunnel to identify the
noise elimination volume needed within frequency spectrum values achieved through
on-site testing noise source for each type of fans. At the same time, package
bedrail circle wind tunnel with strong sound absorptive material for decorative
surface are used to enhance absorptive effect. As we all know, frequency spectrum
values of the noise source that reaches ultimate value is not merely one, but
the sound elimination volume needed varies from frequency spectrum values. So,
the blocked structure of the sound absorption for high and intermediate frequency
has been adopted to achieve good result.
After installing the equipment according to requirements, the ultimate noise value
won't exceed from 85 to 90 dB.
The mufflers are mainly used for centrifugal fans. In addition, we can provide the
custom-made mufflers for LUOCI fans, air compressors and so on, according to the
customers' special requirements. Welcome to inquiry and selection.
