  Roots blower Not only is the noise intensity very high, but also has complex and continuous frequency components. In order to quantitatively describe the distribution of its noise energy in the entire audio frequency range, octave filters are often used in noise measurement to conduct spectrum analysis and test on the noise at eight octave frequency bands from 63 Hz to 800 Hz, so as to obtain the noise spectrum characteristic curve of the sound source, that is, the relationship curve between octave sound pressure level and frequency. Today, I will take you to know how to solve the noise problem of Roots blower.

The characteristics of noise spectrum curve of roots blower introduced by roots blower manufacturer include:
First of all, its noise spectrum is wide, that is, there is high noise in a wide frequency range, and low intermediate frequency noise is the main component. When the static pressure is low, that is, the load is small, the peak frequency is usually about 125 Hz at the low frequency; When the pressure rises to the rated static pressure, a new noise peak will appear at the intermediate frequency of about 500 Hz. This shows that with the increase of the working pressure of Roots blower, the medium and high frequency noise will increase significantly. Roots blower
       

Solve the noise problem of Roots blower

The noise intensity and frequency spectrum characteristics of roots blower are not only related to the working static pressure of roots blower, but also to the flow and speed of roots blower. For example, with the increase of flow rate, the noise also increases. When the speed is doubled, the noise of roots blower can increase by about 5~10 dB, especially the increase of medium and high frequency noise.
In addition to the consideration of tuyere noise, the solid sound transmission of the body noise and vibration of roots blower should also be paid attention to according to the site conditions. The roots blower makes great noise when the axial flow roots blower works, and the noise of roots blower also increases with the increase of air volume and air pressure. Generally, there are several methods to solve the noise problem of roots blower:
       

Solve the noise of Roots blower

1、 The noise of the enclosure and motor can be solved by installing a sound insulation cover. The roots blower is placed in an independent roots blower sound insulation room, where sound absorption and insulation are carried out.
2、 A silencer is installed outside the exhaust outlet of Roots blower, with built-in silencer inserts to reduce the noise when passing through the silencer with special structure. Muffler is an effective measure to reduce the radiation from the air inlet and outlet of aerodynamic equipment or the noise transmitted along the pipe.
3、 Louvers outside the ground floor shall be silencing louvers as far as possible. Roots blower
4、 The roots blower is hung with damping spring hanger shock absorber.
The above is the solution to the noise problem of Roots blower. I believe that after reading the above, you should also understand it. I hope it will help you.
