Due to the strong noise produced in the process of suction and exhaust of Roots blower, it is called "sound tiger" in mechanical products, which seriously restricts the development of production. If we want to use roots blower in production activities, we must take some noise reduction measures.
According to the characteristics of Roots blower, the noise control of blower mainly starts from sound absorption and sound insulation, and takes the following measures: establishing sound insulation cover, installing muffler, pipe binding, using hose and connection, using sound insulation doors and windows, pasting sound absorption materials, etc.
Through the installation of muffler at the inlet and outlet of Roots blower with serious noise, the sound absorption and sound insulation are targeted. This method is simple and easy to operate, has strong adaptability to the fan, and does not change the structure and precision of Roots blower. This noise reduction method is an effective and widely used noise reduction measure for Roots blower.
Based on the data from the actual test spectrum characteristics of various industrial wind turbine noise sources, mainly based on the absorber design and fluid channel to determine the required noise reduction ability of the spectrum range. At the same time, a narrow rectangular channel and a large surface of sound absorption material are used to enhance the sound absorption effect.
