Dynamic balancing is a precision maintenance service aimed at correcting the unbalance of rotors and rotating assemblies <\/strong>in order to reduce vibration, mechanical stresses, and structural fatigue during operation.<\/p>\n

In industrial plants, it is typically applied to fans, pumps, blowers, motor rotors, turbines, couplings, pulleys, rollers,<\/strong> and other equipment where an uneven mass distribution generates undesirable dynamic loads.<\/p>\n

We perform vibration and phase data acquisition, verification of prior mechanical conditions, calculation of correction weight and angle<\/strong>, execution of corrections in one or more planes, and final validation through new measurements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Not always. It depends on the asset, the risk level, and the intervention method. Many cases are resolved in situ<\/strong> with a short shutdown or within a scheduled outage window; for highly critical equipment, the work plan must be coordinated with Operations and Safety. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

No. It corrects the component associated with unbalance, but it does not replace the diagnosis of other causes such as misalignment, looseness, resonance, cavitation, bearing defects, or electrical issues. That is why it is advisable to measure both before and after the intervention. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Shop balancing offers a high degree of control when the rotor can be disassembled; in-situ<\/strong> balancing adds value when disassembly involves high cost, risk, or equipment unavailability. The choice depends on rotor size, accessibility, criticality, and safety conditions. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

It is validated by comparing vibration levels before and after the intervention, operating stability, and compliance with balancing tolerances applicable to the rotor and the machine. In addition, a technical record of measurements, corrections, and the final equipment condition must be kept. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

It depends on the rotor geometry, its length-to-diameter ratio, running speed, and how the mass is distributed. For rigid and narrow rotors, single-plane balancing may be sufficient, whereas longer rotors or those with more complex dynamic behavior usually require correction in two planes to reduce both unbalance forces and moments. The decision should be supported by amplitude and phase measurements, as well as the criteria of the ISO 21940 series. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Before balancing, it is advisable to confirm that there is no significant mechanical looseness, severe misalignment, bent shaft, dominant structural resonances, advanced bearing damage, variable dirt buildup on the rotor, or process instability. It is also important that the machine operates under conditions that are as stable as possible in terms of load and speed. If these conditions are not reviewed, balancing may correct only part of the problem or lead to poorly repeatable results. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
