Do you know the reasons why the processing of square and round ventilation ducts produces noise?
What are the causes of noise during the processing of square and round ventilation ducts?
Causes of noise during the processing of square and round ventilation ducts
Square and round ventilation ducts are essential infrastructure for indoor ventilation and reducing the concentration of harmful gases. What should you do when noise occurs in square and round ventilation ducts?
1. Stop noise from ventilation and cooling equipment through transmission methods. Equip the cooling equipment vents with appropriate silencers, the ventilation and cooling equipment with shock absorbers, connect the vents with plastic pipes, and soundproof the exhaust pipe ventilation ducts. This includes soundproof housings for industrial ventilation and cooling equipment, lining the outer shell of ventilation and cooling equipment with sound-absorbing materials, setting up a dedicated ventilation and cooling equipment room, installing soundproof doors and windows, installing other sound-absorbing equipment, and setting up a ventilation and cooling equipment monitoring center.
2. Reduce noise at the sound source of ventilation and cooling equipment. In areas with stringent noise control standards, select low-noise ventilation and cooling equipment. Under the working air volume and standard pressure of different types of standard ventilation and cooling equipment, airport airfoil blade rotary evaporation ventilation and cooling equipment has lower noise, while forward blade rotary evaporation ventilation and cooling equipment has higher noise. Appropriately reduce the transmission ratio of the ventilation and cooling equipment used to manufacture square and round ventilation ducts. The rotational noise of the ventilation and cooling equipment accounts for the cube of 10 inner rotations per minute of the fan impeller, and the vortex noise accounts for the cube of 6 (or 5) inner rotations per minute of the fan impeller.
3. Immediately inspect, repair, and maintain according to the maintenance schedule. Immediately remove, dismantle, and replace damaged parts. Clear any abnormalities and establish low-noise operating procedures.
Noise Control Solutions for Exhaust Pipe Centrifugal Fans:
Centrifugal fans are widely used in metallurgical industries, chemical enterprises, and major construction projects. They play a very automated role in promoting industrial production and accelerating infrastructure construction. However, the significant noise produced during the operation of centrifugal fans severely damages the acoustic environment, human hearing, and mental and physical health. It hinders normal production and daily life. Noise sources of centrifugal fans: The noise generated by centrifugal fans under a certain load mainly includes natural gas drive noise and reflected noise. The tensile strength of natural gas drive noise is relatively large, and it is an important component of centrifugal fan noise.
