The air volume of a 30kw Roots blower is usually between 20-40m3/min, but the specific air volume depends on multiple factors, including the pressure, speed, model, impeller size, and effective volume of the blower. The following is a detailed analysis of the airflow of a 30kw Roots blower:
1、 The relationship between air volume and pressure
The air volume of the fan will vary with changes in wind pressure. Taking a 30kw Roots blower with a diameter of 150 as an example:
1. When the wind pressure is 14.7kpa, the air volume can reach 29.48m3/min.
2. When the wind pressure rises to 58.8kPa, the air volume may decrease to between 15.70-18.03m3/min.
3. This indicates that as the wind pressure increases, the air volume will correspondingly decrease.
2、 The relationship between air volume and rotational speed
In the same type of blower, the higher the motor speed, the greater the air volume. Therefore, by adjusting the speed of the motor, the air volume of the fan can be adjusted to a certain extent. However, please note that when adjusting the speed, it is necessary to ensure that the fan operates within the rated speed range to avoid damage to the fan.
3、 The influence of model and impeller size
The differences in fan model, model, and impeller size can also affect the airflow of the fan. Different models of 30kw Roots blowers may have different air volume parameter configurations. Therefore, when making a purchase, users should choose the appropriate fan model and brand according to their specific needs.
4、 The impact of effective volume
There is a gap between the two impellers of the Roots blower, which can cause some air to leak back into the front pipeline through the gap during compression. The larger the gap, the greater the leakage, which affects the airflow of the fan. Therefore, in the design and manufacturing process, it is necessary to reasonably control the clearance between the impellers to improve the volumetric efficiency of the fan.
5、 Measurement of actual air volume
In order to accurately understand the actual air volume of a 30kw Roots blower, various measurement methods can be used, such as using an anemometer to measure the air velocity at the outlet and calculating the air volume based on the outlet cross-sectional area, or installing flow sensors on the inlet and outlet pipes of the blower to read gas flow data. These methods can help users better understand the performance parameters of the fan and meet practical needs.
In summary, the air volume of a 30kw Roots blower is affected by multiple factors. Users should choose the appropriate blower model and brand according to their specific needs during the selection and use process, and conduct regular maintenance and upkeep to ensure the normal operation of the blower and extend its service life.
