تشخیص ناهم‌محوری کمپرسور سانتریفیوژ با استفاده از پایش وضعیت و اصلاح آن

Troubleshooting rotating machine by condition monitoring (CM) has many advantages, such as reducing maintenance and repair costs, reducing downtime, preventing unplanned stop, prolongs the life of the equipment. In general, the most common mechanical defects that cause inappropriate vibration behavior include misalignment, shaft bending, loosening of rotating parts, improper installation, misalignment, failure of couplings, and improper installation of bearings. In this research, the effect of soft foot on compressor electric motor vibrations was investigated. Therefore, the vibrations of the electric motor of the air compressor in the oxygen plant of Zarand Iranian Steel Complex were compared, before and after the modification of soft foot of the electric motor . After the initial measured vibrations were higher than the value recorded in the history of the equipment, the obtained data were analyzed and the alignment and soft foot of the compressor were re-checked.
According to the observations, the soft foot of the electric motor was modified. The results show the improvement of the vibration behavior of the electric motor after modifying the of the soft foot
