Bearing Inner Race Fault Detection
A defect in the bearing (BPFI) internal raceway was identified in the S11D @vale single line project, modulating at a frequency of 10.78 Hz. The defect was diagnosed as a crack in the internal track, and the team involved in the monitoring, planning, and execution of the activity is congratulated for ensuring the integrity of the asset.
Good afternoon!
I hope you are all well!
Sharing with you an assertiveness that occurred in the S11D @vale single line project (TCLD), in the vibrational analysis in the bearing 231 68 CCK W33 C3, drum 01 driven from TR-1085-KS-02, we identified a defect in the bearing (BPFI) internal raceway, modulating at a frequency of 10.78 Hz, as mentioned in the open report, the post intervention and perimeter of the replaced bearing, A crack was diagnosed in the internal track as shown in the photo in the image, evidencing the crack and attenuations in the vibrational values, I would like to congratulate everyone involved in the monitoring, planning and execution of the activity, fundamental to ensure the integrity of the asset as a whole.
technique in the vein!
