Ways to improve the suction efficiency of centrifugal fans
The air extraction efficiency of a centrifugal fan directly affects the air volume of the fan. Under normal circumstances, the air extraction efficiency of the fan is directly related to the economic cost of our users. Therefore, in terms of improving the air extraction efficiency of the fan, it is often Our users are most concerned about. We have also said in the previous issues that if we want to improve the performance of the fan, we must know what are the key factors that affect the fan, and making targeted adjustments is the king. Now China Centrifugal Fan supplier is here to introduce two ways to improve the extraction efficiency of centrifugal fans.
First of all, for centrifugal fans, the convexity of the partition is directly related to the air extraction efficiency of the fan. Due to the convexity of the partition, the air flow field is extremely irregular, making the air extraction effect poor. Changing the shape of the suction baffle and adopting the layout is very helpful for the improvement of the suction efficiency of the centrifugal fan, and this is also a widely used method.
Secondly, the air extraction efficiency of centrifugal fans will also be affected by other factors such as the outside world. In a stable air flow field, the stability of the air extraction efficiency of the fan can be well maintained. Once the circumferential uniformity and diameter are damaged Directional uniformity may arouse unconventional flow phenomena such as fan stalls.
The above are just personal opinions compiled by the editor. Although these methods can improve the air extraction efficiency of centrifugal fans, they are not suitable for all fans. Therefore, you still have to choose the way to improve the fan based on your own actual situation and location restrictions.
