Precision Shaft Alignment Acceptance for Fans

Fan Alignment for Stable Operation

     Project technicians adopt dial indicators as precision measuring tools to carry out fine coaxiality calibration on the coupling between induced draft fan motor and impeller. Construction personnel measure radial and end-face deviations item by item, fine-tune the equipment base repeatedly, accurately compensate for thermal and cold expansion differences of the unit, and eliminate eccentricity defects in shaft assembly.

     Shaft alignment of fans is the core acceptance procedure for rotating equipment. Accurate calibration can greatly reduce vibration and noise during equipment operation, cut wear of bearings and couplings, and extend the service life of facilities. The project department strictly abides by equipment erection standards, controls assembly accuracy at every position through refined inspection and calibration, and ensures long-term stable and efficient operation of the flue gas and air system.
