Huge industrial fans are popular among customers because they don't occupy the space of the workshop and save energy. So, what kind of huge industrial fans is good? The blades of the fans are the key elements. Next, we will analyze the characteristics of the blades of huge industrial fans with excellent functions from the following aspects: blade spacing, the total number of blades, blade smoothness, and blade material.
1. Regular blade spacing of huge industrial fans
Too small blade spacing will lead to airflow excitation and the increase of the conflict of the blade surface, which reduces the fan speed. Too large blade spacing will lead to insufficient wind pressure. Keep correct blade spacing is a basic element.
2. High blade smoothness of huge industrial fans
It is an index that is not influenced by design factors. The smoothness of the blade mostly depends on the big fan manufacturer's formed mold and post-processing. Besides the factor of blade curve, the unevenness on the blade will cause turbulence and increase conflict, which will reduce the efficiency of the fan, increase its wear and tear as well as increase the working noise. Therefore, the smoothness of the blade surface is strictly controlled.
3. The blade of huge industrial fans is made of aluminum-magnesium alloy with fine and average quality
Generally, the blade made of aluminum alloy has obvious tenacity. It can not receive a large level of physical deformation, and will also vibrate in the process of pushing the air, but the vibration is small. The other serious vibration is caused by the uneven refinement of blade quality and the eccentricity between the center of mass and the axis of rotation. When the fan blade area (mass) or eccentricity is large, the fan and even the radiator will vibrate, which will affect the chassis of a huge industrial fan.
