Product Description
One.fan silencer
According to the spectrum characteristic data obtained from the actual test of noise sources of various industrial fans, it is the main basis for designing sound absorbers and fluid channels to determine how much noise reduction is needed in which frequency spectrum ranges. At the same time, narrow rectangular channels with large sound absorption materials are adopted to enhance the absorption effect. In addition, when the noise sources of fans are at the maximum noise level, there are often more than one spectrum value, and the requirements for noise reduction are different for different frequency bands.
For this reason, the series of ventilation duct silencers and fan silencers are of impedance acoustic flow type, and the resistive structure with sound absorption and noise reduction effects on high and medium frequency noise and the resistive structure with sound absorption and noise reduction effects on medium and low frequency noise are adopted.
At the same time, two sound absorption and noise reduction zones of high frequency and low frequency are adopted in the resistive channel to widen the noise elimination frequency band to the maximum extent, so as to achieve good noise elimination and noise reduction effect.1.Introduction of Muffler for Chip (JSGF) Fan
Chip muffler, as the name implies, is equipped with a muffler inside. When the sound flow passes through the muffler, it will be absorbed by the internal muffler cotton. It is a kind of equipment for muffler mainly through the internal muffler. It is suitable for the inlet and outlet of the fan, and the muffler effect is generally required. This model is selected.
The connection mode of chip muffler is generally flange connection, which can be fixed with lugs or feet when installation.
2.Introduction of New Type High Efficiency Compound (JSGZ) Fan Muffler
The new high-efficiency compound muffler is an effective combination of volume expansion and impedance sound absorption materials through appropriate structures. Principle: After the gas (steam) flow is expanded by the internal expansion device, a plurality of steam (gas) flows through the multi-stage silencing device for effective silencing, thus achieving the best silencing effect.
Scope of application: It is suitable for effective noise elimination equipment at the inlet and outlet of clean gas (steam) flow with high noise elimination requirements.
Advantages:
(1)Good noise elimination effect;
(2) Low resistance and high safety;
(3) Long service life and convenient installation.
3.Introduction of JSGS Type Fan Muffler
Multi-tube patented muffler is a new type of structural muffler developed by our company. The muffler is muffled by muffling pipes and is filled with sound-absorbing materials. When the airflow enters the muffler, it first passes through the muffler pipe.
At this time, the airflow contacts the muffler material in the muffler pipe, and it is effectively muffled by the sound-absorbing material in the muffler pipe.
It is suitable for equipment with high requirements for muffler effect, and it is also suitable for effective muffling of more granular objects in the gas (steam) flow.
