What are the methods to eliminate noise from oilless air compressors?
Oil-free air compressor is a production auxiliary equipment with the characteristics of smooth rotation and high efficiency. So do you know what methods to eliminate noise from oilless air compressors? Below is our share.
1. Oil-free air compressor sound insulation cover
In many workplaces with high environmental requirements, the noise requirements for oil-free air compressors are often very high. In this case, the noise radiated by the casing of the air compressor and its mechanical construction must be sound-insulated. For example, the entire oil-free air compressor is equipped with a sound insulation cover. Secondly, the design requirements for the sound insulation enclosure must also ensure its sealing performance in order to obtain better sound insulation effect.
The sound insulation cover can be designed to be disassembled, retaining the access door and observation window, and leaving enough heat dissipation space for the unit. Only by installing mufflers at the inlet and outlet can this type of sound insulation cover meet the noise elimination requirements of oil-free air compressors.
2. muffler mounting
When installing an oil-free air compressor, you can lead the air inlet to the outside and install a muffler. Since the recent noise has low-frequency characteristics, the types of mufflers that can be installed include: impedance composite muffler, micro-perforated plate conforms to muffler, pipe muffler, etc.
3. sound absorption by air storage tank
Because the working principle of an oil-free air compressor is to continuously compress and transport gas into the gas storage tank, and after the compressed gas enters the tank, it will vibrate under the action of the pulse of the air flow. When the gas vibrates, it is accompanied by strong noise, which stimulates the storage tank shell vibration radiates noise. In addition to adopting sound insulation methods, this noise can also be hung on the inner wall of the gas storage tank to use the sound absorption effect of the sound absorption device to hinder the formation of sound waves in the tank, thereby achieving the purpose of noise reduction.
The above methods for eliminating noise from oilless air compressors are shared here. I hope this article will be helpful to everyone. If you still need to know more about oil-free air compressors, you can come to us to understand, and we will have professionals to answer you!
