Causes of Vibration in Centrifugal Fans7.0

There are many causes of vibration in rotating machinery; let us examine the causes of vibration in centrifugal fans. 8. Irregular knocking during reverse operation During shutdown, irregular knocking noises from the unit are only observed when the gear clearance in the gearbox increases or the mechanical connections are inadequate. Recommendations to Prevent Recurrence Vibration issues pose a significant risk to the smooth operation of our machinery. We must find a one-off solution to prevent frequent occurrences of vibration issues. Bearing Housing Foundation Bolts Loose bearing housing foundation bolts may increase vibration, so we must prevent fasteners from becoming loose. To avoid frequent loosening, we must check the following points. The size of the foundation fasteners must not be too small. Foundation fasteners must be fitted with flat washers and spring washers of the correct size. The alignment of the bearing housings must be checked to ensure that each fastener is centred. Fasteners must be fitted with a lock nut to permanently resolve the issue of bolts frequently coming loose. Routine inspection of fasteners to prevent vibration problems.
