The difference in functions between a Roots blower and a centrifugal blower.
Release time:
2022-04-06
They work differently; centrifugal fans use curved blades to throw gas to the casing through centrifugal force, while Roots blowers use two figure-eight shaped blades with a very small gap between them, relying on the compression of the two blades to push gas to the outlet. Due to their different working principles, they generally have different working pressures; the outlet pressure of Roots blowers is relatively high, while that of centrifugal fans is lower. The airflow is also different; Roots blowers are generally used in places where the airflow requirement is not high but the pressure requirement is relatively high, while centrifugal fans are used in places where the pressure requirement is low and the airflow requirement is large. The manufacturing precision is different; Roots blowers require high precision and strict assembly requirements, while centrifugal fans are relatively loose. Of course, there are some minor differences that I won't mention. Roots blowers are a type of high-pressure fan, and Roots blowers are positive displacement fans, where the airflow is proportional to the speed, transporting gas from the intake side to the discharge side. If the load requires a constant pressure effect, a centrifugal fan is used. This is because centrifugal fans are constant pressure fans, where the main working parameter is air pressure, and the output airflow varies with the pipeline and load, while the air pressure changes little. Centrifugal fans have low air pressure. The air compression process usually occurs through several working impellers (or stages) under the action of centrifugal force.
