dc.description.abstract In Khartoum Refinery Company (KRC) Pump 1104B suffers of high vibration level. Many corrections had been done to find out the problem but failed. Vibration analysis techniques is used to find out the root causes of the pump vibration. New data collected from the pump, indicates high vibration in the pump drive end (DE). After collection data, was uploaded to software in which set up database of measurement points. Spectrum analysis; was used. The analysis result indicates that the angular contact bearing in the pump drive end has been failed. During this work theoretical analysis through mathematical model had been done with the assumption that good bearing has good oil film damping coefficient to restrict the rolling elements movement while the shaft is rotating the damping loss percentage illustrate the bearing status and its residual life time can be estimated through Providing the program with the bearing ball mass and diameter in addition to the equipment rotational speed in RPM to find out the maximum amplitude that will illustrate no damping coefficient x-axis in rms. The root cause of vibration was found the comparison between the theoretical investigations and the measuring data show closed similarity. The visual inspection results after bearing box dismantling is angular contact bearing defect which confirmed the theoretical &software analysis of finding vibration root causes. Bearing replacement was carried out. New data collected from pump bearing drive end and sent to vibration analyzer to verify the repair. These results can lead to apply this mathematical analysis with the equipment’s if their software not available to find out the root cause of vibration because the vibration phenomenon is same. en_US
