Bearing Defect Frequency
A rolling element bearing shows increasing vibration at non-synchronous frequencies. The spectrum shows peaks at 5.4× and 10.8× running speed. What is the likely cause?
Attempts remaining: 3Case ID: case-003
Misalignment Pattern
A motor-pump coupling shows high vibration at 2× running speed in the axial direction. Radial vibration is normal. What fault pattern does this indicate?
Attempts remaining: 3Case ID: case-002
Unbalance Detection
A centrifugal pump shows elevated vibration at 1× running speed. The spectrum shows a dominant peak at 1800 CPM with 0.5 in/s RMS. What is the most likely fault?
Attempts remaining: 3Case ID: case-001
