The vibration of centrifugal fan is a common concern of users and manufacturers

The vibration of centrifugal fan is a common concern of users and manufacturers. Excessive vibration, will make the bearing temperature rise, wear intensifies, serious will also make the anchor bolt fracture, bearing box cracking, and even make the impeller cracking and disintegration. The best way to reduce the vibration is to move the balance: the balance of the impeller and the whole balance. Why the impeller in the dynamic balancing machine to reach the standard, but also to the whole machine balance, because the fan vibration is generated by the periodic interference. According to the formula of mechanical vibration: X=-F/K, in the range of elastic deformation, the magnitude of vibration X is directly proportional to the interference force F, and inversely proportional to the rigidity of the system K.
