Effect on Bearings in Rotating Components by Vibration Analysis: A Case Study in Steel Plant

Abstract

In the present work, the condition of machines and structures are determined by the condition monitoring technique of rotating machineries through vibration analysis. Here, the amplitude and frequencies of vibrating machines play a key role in the judgement of predicting the condition of the machineries. Henceforth, we have selected critical equipment for the testing which includes mill stands of bar rod mill (BRM-2) from the steel manufacturing industry. Now the amplitude of the equipment was taken by using vibrometer at different parts of the equipment, then by the FFT analyzer, the comparison was made between the parameters like amplitude versus time and amplitude versus frequencies. At the end with the help of the plots obtained the critical part of the equipment which was responsible for vibration was identified. Finally, with the remedial methods, the vibration was reduced to the acceptable level.
