Two methods to improve the pumping efficiency of centrifugal Fan

Jun 01, 2019

The exhaust efficiency of centrifugal fan directly affects the air volume of the fan. Under normal circumstances, the exhaust efficiency of the fan is directly related to the economic cost of our users. Therefore, in order to improve the exhaust efficiency of the fan, the problem of the exhaust efficiency of the fan is directly related to the economic cost of our users. It is often the concern of our users. In order to improve the use effect of fan, it is necessary to know the key factors that affect the fan, and to make a specific adjustment in order to be effective.

First of all, for centrifugal fan, the outer convexity of the partition is directly related to the pumping efficiency of the fan. Because the outer convexity of the partition will make the air flow field extremely irregular, the pumping effect is not good. It is very helpful to improve the pumping efficiency of centrifugal fan by changing the shape of exhaust partition and adopting the shape of layout, and this method is also widely used.

Secondly, the pumping efficiency of the centrifugal fan will also be affected by other factors, such as the outside world. In the stable air flow field, the stability of the exhaust efficiency of the fan can be well maintained. Once the circumferential uniformity and radial uniformity are destroyed, It may cause unconventional flow such as stall of fan.

The way to improve the efficiency of centrifugal fan is to change the shape of the separator and control the environment. Although these methods can improve the pumping efficiency of centrifugal fans, they are not suitable for all fans. Therefore, we should choose the way to improve the fan according to the actual situation and the limitation of the place.www.jnblower.com
