Comparison table of power and air volume of Roots blower
introduction
The power and air volume of a Roots blower are two important parameters for measuring its performance, and the relationship between the two directly affects the application effect of the blower. This article will explore in detail the comparison table between the power and air volume of Roots blowers, helping users better understand and choose suitable equipment.
Comparison table of power and air volume of Roots blower
1. * * 5 kW Roots blower * *:
-* * Airflow * *: 5 to 10 m3/min
-Pressure: 0.1 to 0.3 bar
2. * * 10 kW Roots blower * *:
-* * Airflow * *: 10 to 20 m3/min
-Pressure: 0.2 to 0.4 bar
3. * * 20 kW Roots blower * *:
-* * Airflow * *: 20 to 40 m3/min
-Pressure: 0.3 to 0.5 bar
4. * * 30 kW Roots blower * *:
-* * Airflow * *: 30 to 60 m3/min
-Pressure: 0.4 to 0.6 bar
5. * * 40 kW Roots blower * *:

-Pressure: 0.5 to 0.7 bar
The relationship between power and air volume
The relationship between power (P) and air volume (Q) can be expressed by the following formula:
\[ P = \frac{Q \times \Delta P}{\eta} \]
Among them\ (\ Delta P \) is the pressure difference of the fan\ (\ eta \) is the efficiency of the fan. For Roots blowers, the higher the power, the higher the air volume, but the specific value is affected by various factors.
Power and air volume adjustment in practical applications
In practical applications, users may need to adjust power and air volume according to specific needs. This can be achieved through the following methods:
1. * * Variable frequency speed regulation * *: By installing a frequency converter, the speed of the fan can be adjusted to control power and air volume.
2. Valve adjustment: Install regulating valves at the inlet and outlet of the fan to adjust power and air volume by changing the cross-sectional area of the airflow channel.
3. * * Replace rotor * *: In some cases, replacing rotors of different sizes or shapes can also adjust power and air volume.
conclusion
The comparison table of power and air volume of Roots blower is an important basis for users to choose and use equipment. By understanding the relationship between power and air volume, combined with application requirements and environmental conditions, users can choose the most suitable model to ensure the operation of the fan.
