Every rotating impeller has small differences in weight distribution caused by casting, welding, wear or dust build-up. At speed, that imbalance becomes a force that shakes the whole machine.
Signs your fan is out of balance
- Visible vibration of the casing, base or ducting
- Bearings that run hot or fail early
- Rising noise or a rhythmic humming
- Loose bolts and cracked foundations or welds
Static vs dynamic balancing
Static balancing corrects weight in one plane and suits narrow, disc-like rotors. Dynamic balancing measures and corrects imbalance in two planes while the rotor spins, which is the right method for most industrial impellers and fan rotors.
Benefits
- Longer bearing and motor life
- Lower vibration, noise and energy loss
- Fewer breakdowns and less unplanned downtime
- Safer operation at higher speeds
When to balance
After a new impeller is made, after repair or re-coating, after heavy wear or build-up, and whenever vibration trends upward during routine checks.
