Professional secrets: the working mechanism and characteristics of Roots fan, centrifugal fan and Roots fan how to choose

With the continuous progress of industrial technology, the application of various fan equipment in industrial production has become more and more extensive. Centrifugal fans and Roots fans, as common fan equipment, play an important role in the industrial field. In this paper, the working mechanism and characteristics of the Roots fan in-depth mystery, while analyzing the characteristics of centrifugal fans and Roots fans, to provide readers with a reference for the selection of fan equipment.

First, the working mechanism of Roots fan

Roots fan, also known as "root fan", it is a centrifugal exhaust fan without screw. The working mechanism of Roots fan is very unique, it adopts the double rotor rotating at the same time, through the continuous suction and exhaust, the gas will be transported to the set position. Inside the Roots fan, two rotors equipped with blades bite each other and by rotating the air is sucked in through the inlet and then discharged. Since the air pressure inside the Roots fan is generated by the two side-by-side impellers, it ensures stability during operation. The working mechanism of Roots fan is the basis of its efficient work.

Characteristics of Roots fan

Compared to other types of fans, Roots fans have unique characteristics. Firstly, Roots fans produce less pulsation during operation, which is important for conveying applications where airflow is a requirement. Secondly, Roots fans can work without oil, which greatly reduces maintenance costs. In addition, the simple structure of Roots fans makes them less prone to failures and has a long service life. Finally, Roots fans have a high pressure ratio and can be used to convey high pressure gases. These characteristics make Roots fans widely used in many fields.

Third, the characteristics of centrifugal fans

Compared with Roots fan, centrifugal fan is also a common fan equipment. Centrifugal fans generate airflow mainly through centrifugal force, and then the gas is drawn in and discharged through the rotation of the fan blades. Compared with Roots fan, centrifugal fan has the advantages of simple structure, small volume and low price. However, centrifugal fans also have some shortcomings, such as noise, susceptible to return air, low efficiency.

Fourth, centrifugal fan and Roots fan how to choose

In the actual selection of fan equipment, you need to consider the specific use of occasions and needs. If the stability and pulsation of the airflow requirements are high, and the requirement to transport high-pressure gas, then the choice of Roots fan is a good choice. And if for the lower cost requirements, the stability of the airflow requirements are not high, you can choose centrifugal fans. In addition, you also need to take into account the maintenance cost of equipment, energy consumption and other factors, after comprehensive consideration to make the best choice.

Fifth, the application areas of Roots fan

Due to its unique working principle and characteristics, Roots fan has a wide range of applications in various fields. First of all, Roots fans are widely used in sewage treatment plants for oxygenation and gas transportation. Secondly, Roots fans can also be used in mining, chemical industry, electric power and other fields for conveying raw materials, exhaust gas treatment, gas circulation and so on. Therefore, Roots fan plays a very important role in modern industrial production.

Six, centrifugal fan application areas

Centrifugal fan has a wide range of applications in industrial production because of its simple structure and convenient operation. Centrifugal fans are often used in ventilation, air conditioning, boilers, dust removal and other fields. In the field of building ventilation and material transportation, centrifugal fans also have a wide range of applications.

VII. Conclusion

To summarize, Roots fan and centrifugal fan are both common fan equipment, playing an important role in industrial production. Through its working mechanism and characteristics of the mystery, can help you better understand these two kinds of equipment, and in the actual choice can be based on demand to make the right choice. I hope this article can provide readers with some help, thanks for reading!
