Methods to improve the suction efficiency of centrifugal fans

1. For centrifugal fans, the convexity of the diaphragm is directly related to the air extraction efficiency of the fan, because the convexity of the diaphragm will make the air flow field irregular, making the air extraction effect unsatisfactory. Changing the shape of the suction baffle and adopting the layout form is of great help to improve the suction efficiency of the centrifugal fan, and is also a relatively common method.

2. The suction efficiency of the centrifugal fan is also affected by external factors. In a stable airflow field, the suction efficiency of the fan can be kept stable. Once the circumferential uniformity and radial uniformity are destroyed, the fan may be damaged. Stalls and other flow phenomena.
