In addition to generating relatively large air volume, axial flow fan also has air extraction function. In the process of air extraction, it will produce great suction. However, we still have some methods to strengthen the air extraction efficiency of fan. What are the specific methods?
1. The convexity of baffle plate is indirectly related to the frequency of axial flow fan. Changing the shape of the induced draft plate and adopting the arrangement method are very useful for improving the frequency of the fan. Because of the convexity of the baffle, the flow field of the atmosphere becomes extremely unregulated, and the air entrainment effect becomes worse.
2. A stable cyclone can maintain the stability of fan frequency. If the symmetry of circumferential position and radial position are destroyed, it can cause urgent activity scenes, such as fan stall. The discharge frequency of axial flow fan is affected by the reaction of external energy.
By changing the shape and setting the cyclone, we can strengthen the extraction efficiency of the axial flow fan through the above operations. So as to bring more favorable conditions for improving the service efficiency of the fan.
