How to distinguish roots blower from centrifugal blower?

I believe that we will use many fans in our work. Similarly, there are many classifications of fans. Many people do not understand them Roots blower It is not clear from the centrifugal fan. Today, Xiao Bian will take you to understand the difference between the two?

1、 Different performance characteristics
Compared with the pressure of centrifugal fan, the pressure of roots blower is generally greater than that of centrifugal fan. Compared with the air volume, the flow of centrifugal fan is greater than that of roots blower. Roots blower is mostly used in aquaculture, coal chemical industry, cement, sewage treatment, smelting, building materials, power and other industries.
2、 Different manufacturing precision
     

 How to distinguish roots blower and centrifugal blower

Roots blower requires high precision and strict assembly requirements, while centrifugal blower is relatively loose.
3、 Constant flow: Roots blower is used if the load requires constant flow effect. Because Roots blower is a constant flow fan, the main working parameter is the air volume, and the output pressure changes with the change of pipe and load, and the air volume changes little.
4、 Pressure
The selection pressure of centrifugal fan is generally below 980PA, while the pressure range of Roots blower is 9.8kpa-98kpa. Generally speaking, centrifugal fan
The pressure is less than the pressure of roots blower.
5、 Flow
Due to different working conditions, centrifugal fans mainly provide flow, followed by pressure; Roots blower needs to overcome certain pressure. In comparison, the flow is smaller than that of centrifugal fan.
I believe that after reading the above, you should also understand the difference between Roots blower and centrifugal fan.
