Recommendation: characteristics of Roots blower and structure principle of muffler
According to different uses and different industries, Roots blower It can be used in a variety of systems in industrial production and life Roots blower It has many advantages and features, so it can be used for For example, sewage treatment aeration, cement production desulfurization oxidation fan, food processing, grain transportation, aquaculture can be used to increase the oxygen in fish ponds, increase the density of fish fry, and increase the number and density of aquaculture. There are also pneumatic conveying Roots blower It is mainly used in the transportation of feed lime powder, monosodium glutamate, bean skin and silica, starch fish meal and other powder materials, liquid slurry chemical aeration and mixing, which is widely used. Up to now, no one can fully explain the use of Roots blower. To Dali, steel mills, power plants, cement, chemical industry, foundry, flour and other national economic departments will use, apply In various fields and industries.
1、 Main features
1、 Roots blower The internal impeller does not need friction, because there is no friction when the impeller is running in the body and does not need internal lubrication, so the gas discharged is pure oxygen without oil. It is an ideal mechanical fan to provide clean oxygen for chemical industry, food industry, etc.
2、 Roots blower Is a positive displacement blower, in the use process, the air volume changes little with the pressure. But the air volume will change with the speed of the fan. Therefore, the pressure selection range is wide, and the air volume can be selected by selecting the fan speed.
3、 Blower High speed rotation, the clearance between the rotor and the rotor, between the rotor and the main body is small, the leakage is less, and the volumetric efficiency is high.
4、 Blower Its structure determines that the mechanical friction loss is very small. Because only the bearing and gear pair have mechanical contact in material selection, the rotor, housing and gear have sufficient mechanical strength. Stable operation and long service life are the main features of blower products.
5、 Blower The rotor is statically and dynamically balanced. The fan runs smoothly and has the least vibration, which is also one of the biggest advantages.
Nothing is absolute, Roots blower There are advantages, but there are also disadvantages. The biggest disadvantage is high noise, which is called mechanical tiger. We have designed and installed muffler parts for Roots blower, which greatly reduces the noise value. Roots blower The noise source, the spectrum value is often more than one is, but for different spectral bands, its muffler requirements are different, let's have a look Roots blower muffler The principle and structure of the system are as follows
Structure and principle of muffler
Roots blower muffler It is developed according to the noise reduction principle of noise barrier. The muffler has excellent acoustic performance and good aerodynamic performance. The structure is reasonable and easy to install. It is a kind of honeycomb muffler with large air volume. The multi chamber rubber straight pipe channel and cross shaped sound absorption plate are used to ensure sufficient sound attenuation in a wide frequency range. muffler The structure consists of many parallel muffler tubes. A porous sound absorbing material is arranged in the silencing tube. In order to reduce the radiation sound caused by the vibration of shell wall caused by air flow, a reinforcing rib is arranged on the shell. The fan muffler, centrifugal fan muffler and induced draft fan muffler all adopt the principle of resistance sound absorption and noise reduction with good effect of neutralization and high frequency broadband characteristics, and have good effect on low, medium and pulsation characteristics. Noise reduction principle and microporous muffler and impedance composite muffler. Therefore, the muffler series of ventilation duct and blower are impedance acoustic flow type. Resistance structure is used to absorb and reduce high frequency and medium frequency noise, and to reduce medium and low frequency noise. In order to achieve good noise reduction effect, the high frequency and low frequency sound absorption and silencing areas in the resistive channel are widened.
The above is Roots blower And Roots blower The principle of noise reduction system muffler, for the new contact or about to contact Roots blower We can pay more attention to our website. We will bring you more news and technical articles about roots blower in the future.
