Analysis of Factors Affecting the Performance of cross flow blower

(Summary description)The cross flow blower uses a relatively long barrel-shaped fan impeller to work. The diameter of this barrel-shaped fan blade is relatively large. Because of the large diameter, a relatively low speed can be used on the basis of ensuring the overall air circulation. Thus, noise due to high-speed operation is reduced.

Information

  The cross flow blower is also called a cross flow blower. The impeller is multi-blade, long cylindrical, and has forward multi-wing blades.

Cross flow blower

  1. The cross flow blower uses a relatively long barrel-shaped fan impeller to work. The diameter of this barrel-shaped fan blade is relatively large. Because of the large diameter, a relatively low speed can be used on the basis of ensuring the overall air circulation. Thus, noise due to high-speed operation is reduced.

  2. The fan blades of the cooling fan are carefully calculated, and the distance between the fan blades is intentionally disordered, presenting a situation of "unequal distance": this is also very simple, it is to try to make the sound produced by the rotating fan wheel and the air "Irregular" becomes "a piece" of wind, rather than wind that is concentrated on a certain frequency band.

  3. The impeller of the high-quality cross flow blower has been dynamically balanced: just as the wheels of the car need to be dynamically balanced, the wind wheel of the air curtain machine also needs to do this work. In short, it is to maintain the balance of the wind wheel in the running state. , reduce noise, and prolong fan life.

  4. Use high-quality cross flow blower blade manufacturing materials: The cooling fan impeller in the air curtain is very long. If such a barrel-shaped fan blade is made of inferior materials, it can save a lot of costs, but it cannot be rotated. How long will it be deformed!

  5. Use a high-quality cross flow blower: the wind wheel is driven by a motor. If the motor is of poor quality, it cannot run normally or is weak to start, it will not work.
