Factors affecting the air volume of industrial large fans:
1. The blade diameter of the industrial large fan, under the same conditions, the larger the diameter of the blade, the larger its coverage and the greater the air volume.
2. The design of industrial large fan blades, the design of blades will also affect the wind speed, most fans adopt three-dimensional structure, variable section streamlined blades follow the actual design of equal length, moving along the length direction of the blades from the center point. The tip of the leaf moves, and the width of the leaf gradually narrows, from root to tail width of 29.8 to 19.2 cm. This ensures that the entire blade runs in the average wind direction and that there are no hollows in between, which improves wind efficiency.
3. The angle of industrial large fan blades, the angle of industrial large fan blades will also affect the air volume, most of the fan blades are three-dimensional, and the conical air flow is composed of unique blades tilted upwards 3 degrees is 30% higher coverage, and the invalid coverage area of each fan exceeds 1500 square meters.
