Whether the speed of Roots blower is high or low, What is the speed of Roots blower related to:

High or low rotation speed of Roots blower

Generally, the speed of roots blower determines its own noise level, so it should select the type selection of roots blower with low return speed. At the same time, if there are requirements for the flow of roots blower,
We should try our best to choose the Roots fan type with wider blades or larger size, but the price of this type of fan is often high. The high speed means that the Roots blower has a small volume, and the same air volume naturally requires several more turns

Whether the rotation speed of roots blower is high or low is better, and what is the rotation speed of roots blower?

The rotating speed should be no more than 2000 rpm. The quality is very stable, but the noise is higher. From the perspective of life, the rotating speed is lower, but the price is cheaper. Choose according to your own situation.

In addition, it also determines the service life. Because of the wear of the rotor and casing of roots blower, the roots blower with the same parameters and different rotating speeds will have a longer service life than the roots blower with the same parameters and different rotating speeds. And then
Wind speed (flow): when the casing volume is the same, the flow of the fan with fast speed is larger than that of the fan with slow speed. So we try to fix the speed of Roots blower to meet our needs.

The judgment standard of rotating speed depends on the size and model of the fan. Small fans can rotate at a higher speed, mainly because of the accuracy of the dynamic balancer when Roots blower is manufactured. The higher the accuracy, the greater the speed,

High or low rotation speed of Roots blower

Whether the speed of Roots blower is high or low, what effect will it have on the service life of Roots blower?

But at present, the precision of dynamic balancing instruments in the world is limited and large Roots blower The speed should be lower. A small Roots blower can rotate faster. When selecting Roots blower, try to select medium and low speed, so as to increase the service life of Roots blower.

The above information is provided by Roots blower manufacturer: the speed of Roots blower is fast
