Tips: What Affacts the Performance of Inflatable Air Blowers?
Is the air pressure of the inflatable air blower fan proportional to the air volume? Maybe we will have such a question some time. As a useful wind energy utilization device, air blowers are now used more and more widely.
So, the number of blades and the installation angle of the small air blower were tested and analyzed. The NACA 4425 blade is used in the test. The blower fan can manually adjust the number of blades and the installation angle of the blade, and work in the relatively stable airflow field of the wind tunnel. The results show that the number of blades has a great influence on the performance of the blower. At low wind speeds, the blower performance is significantly improved with the addition of the number of blades. During this period, the maximum wind energy utilization factor of the six blades is 0.15. The mounting angle is also another factor influencing the performance of the fan. The blower performance has been greatly changed under the three viewpoints of 150, 22.50, and 30.
