There may be various reasons for high vibration of centrifugal fans, mainly including the following:
1. Improper installation: If the fan is not installed horizontally or symmetrically, this may result in an imbalance, which can cause vibrations. Unstable installation or a weak foundation can also exacerbate vibrations.
2. Unbalanced fan impellers: Uneven mass distribution of fan impellers, or accumulation of dust, corrosion, or wear on the impellers can lead to unbalanced impellers, which in turn can trigger vibrations. Regular inspection and cleaning of the impeller can reduce this situation.
3. Damaged or insufficiently lubricated bearings: Bearings are a key component in the operation of the fan. If the bearings are badly worn or lacking in lubricant, it will lead to unstable rotation of the bearings, which will cause vibration. Regular maintenance and replacement of bearings are important measures to prevent vibration.
4. Uneven air flow during fan operation: If there is a blockage in the air intake or if the fan access is compromised, uneven air flow can also cause the fan to vibrate irregularly. Ensuring that the air intake of the fan is clear and unobstructed can effectively minimize such problems.
5. Interference from external factors: Changes in the environment around the fan, such as temperature fluctuations or external mechanical shocks, can also lead to increased vibration.
