The hazard of airflow backflow in the flow path of the centrifugal fan impeller? 1. Reflow itself is ineffective power, consumes power, and reduces fan efficiency; 2. Reflow is a turbulence that produces noise; 3. The returning gas occupies the flow channel, reduces the flow channel area, changes the wind speed and the airflow inlet and outlet angle, and reduces the fan efficiency; Therefore, the impeller design should minimize the backflow of the airflow. Reduce the reflow in design: 1. Simulate the optimal gas flow line to define the flow channel geometry; 2. Make good roundness and rounded surface on the production, and reduce the gap of the joint; 3. The change in fluid velocity increase or decrease in the streamline geometry should be slowed down, and should not be increased or slowed down rapidly; 4. Where the pressure difference between the inside and the outside is large, try to increase the pressure loss and try not to make the backflow; 5. Increase the number of blades as appropriate to reduce the distance between the pressure surface and the suction surface.
