Axial Fan Balancing Machine

Today there are many different kinds of fans, the main ones: axial, centrifugal, radial, tube axial fan, tangential and exhaust fans. All of them can experience an unbalance. The unbalance is the most dangerous disease, as it is shown in the low-frequency spectrum and the most damaging to the bearings and seals.The fan wheel unbalance occurs due to natural deterioration, which may be enhanced by the presence of solid particles in the pumped air, as well as the adhesion of various materials to the impeller. To avoid the structural damage and severe consequences it is necessary to control the overall vibration level and the vibration at the rotor rotation frequency, and to perform axial fan balancing machine in case of the increase of the rotational frequency component
