Case Study: Vibration Analysis of a Vertical Pump of Cooling System in Fero-Nickel Industry

摘要

The basic goal of this investigation is analyzing the vibration condition of a vertical pump type 165 used fortransportation of a hot water to the tower for natural cooling in fero- nickel industry Feni – Kavadarci – Republic ofMacedonia. For that purpose was used VIBROTEST 60 (Bruel&Kjaer) instrument with appropriate modules. The papershows the procedure for early detection of failure the rolling bearings using vibrating signature of the measurementand analyses the other problems of the elements as results of existing pump cavitation. Some proposal for constructiveintervention on the pump-motor to decrease existing vibration amplitude values are given in the paper.
