The characteristics of the fan type axial flow fan blades

The blade and hub

  1. New type cast aluminum wing blade and hex bolt lock on cast aluminum wheels within;
  2. Blade Angle according to the change of parameters in the field does not need to remove can be adjusted directly;
  3. Wheel hub ratio (wheel diameter and the ratio of the diameter of the impeller) performance and the influence of the energy efficiency of the fan is a lot, so highly emphasized in the product design appropriate than hub.

Leaf blade arrangement

  1. As an ordinary send exhaust fan, the clearance between the cylinder and the fan blade tip is less than 3 mm;
  2. As the fire smoke exhaust fan, the clearance between the cylinder and the fan blade tip is not more than 5 mm;
  3. Impeller adopts the design of the non equidistant between 275 and 400 mm, overlapping to reduce vibration and noise, to avoid the resonance, the noise of the wheels and running of the impeller.
