HOW DYNAMIC BALANCING RESOLVES UNBALANCE FAULT IN ROTATING PARTS

Firstly, unbalance-related issues are common causes of vibration in industrial fans, impellers, and other rotating parts of equipment.

Therefore, unbalance occurs when a rotating part’s center of mass or its inertia axis, is no longer aligned with the part’s center of rotation or its geometric axis. This fault causes an unsteady movement of rotating parts from side to side.

Dynamic balancing services

Above all dynamic balancing is a procedure whereby rotating parts are balanced either by addition or removal of mass while the part is in motion. This procedure can either be done on a single plane or two planes.

In addition, we always recommend rotating equipment to balance per the international ISO reference standard for quality balancing. Contact us today.

The below images shows vibration and balancing results before and after dynamic balancing services for different rotating equipment 

1. balancing of Crusher Fan with motor pump

dynamic balancing of Crusher Impeller
High Vibration of 25.24mm/s was measure from crusher and upon spectrum analysis, unbalance was noticed @16.540mm/sec. A single correction weight of 49 grams was added to the fan and vibration significantly reduced to 4.10mm/sec, with unbalance @0.841mm/sec.

2. balancing of A Flash Dryer

Total vibration of 43.995mm/s was observed, during an initial solo run of the dryer, and the highest peak from the derived spectrum was on the fundamental frequency 1X. Trial weight was calculated, and two correction weights of 139g @ 319.5 and 8.960gr @ 59.4 were added to the impeller. Total machine vibration reduced to 0.913mm/sec after balancing.

3. balancing of impeller Fan

High vibration @ 19.135mm/Sec was observed during the Motor initial test run and unbalance @13.176mm/sec. We added Six correction weights on the fan blade, and total vibration was significantly reduced to 3.69mm/sec, with residual unbalance @0.695mm/sec.
