1. What are the preventive measures for sound insulation and noise reduction of centrifugal fans? In terms of noise control and sound insulation, we can choose sound insulation hood and anechoic chamber to control the noise source in a closed space and control its diffusion. Using the sound-absorbing board in the anechoic chamber or anechoic hood, outsourcing or filling the project can effectively and safely protect the noise formed during the operation of the centrifugal fan, and better ensure the expected effect of sound insulation and noise reduction of the centrifugal fan.

2. What are the preventive measures for sound insulation and noise reduction of centrifugal fans? -Sound absorption and noise reduction: Sound absorption materials and silencers can be used for sound insulation and noise reduction of the ceiling and sound insulation cover of the above-mentioned sound insulation room, so as to ensure that the centrifugal fan can achieve the expected sound absorption and noise reduction effect. The sound-absorbing materials that can be selected are sound-absorbing board, sound-insulating cotton and polyester fabric sound-absorbing board. The related parts of centrifugal fan can adopt built-in muffler or mixed combined muffler to solve the difficulty of noise propagation at the noise source.

3. What are the preventive measures for sound insulation, noise reduction and noise reduction of centrifugal fans? -Use shock absorbers or shock absorbers. If the noise of the reliability analysis of the centrifugal fan is too large, you can choose to use shock absorbers, shock absorbers or shock-absorbing fixed brackets, which can prevent the centrifugal fan from generating vibration and noise at the working stage, and on the other hand, the shock absorber of the turbo fan can reduce the noise from the transmission mode.
