عیب یابی علت خرابی زودهنگام بیرینگ الکتروموتورهای واقع در پمپ خانه کارخانه احیاء مستقیم شماره 2 شرکت جهان فولاد سیرجان

Condition monitoring has many benefits, including reduced maintenance costs, reduced downtime, and extended equipment life. Non-destructive testing (NDT) techniques assess equipment conditions without affecting their structural performance, thus playing an important role in diagnosing equipment health.Among the various techniques investigated for condition monitoring applications, vibration-based techniques are the most popular because the measured vibration from the equipment contains physical information that directly reflects the severity of the fault.n this study, among 7 almost identical pumps located in the pump house, the direct regeneration plant No. 2 of Jahan Foolad Sirjan Company was examined, considering the identical operating conditions and the similarity of faults in all of them, using the vibration analysis technique and FFT diagram analysis.It was shown that a common fault in high frequency vibrations and 100 Hz sidebands can be caused by electrical faults, leading to bearing failure and reduced tonnage production.After identifying the defect and making detailed plans to strengthen and modify the earthing system of this equipment, it reduced high-frequency vibrations and prevented premature failure of these pumps.
