Identifying "peak" frequencies (1X, 2X, harmonics) and sidebands.
Operating a single pump reduced the back pressure significantly (from 30 ft to 10 ft of water), causing the pump to operate outside its design parameters and into a cavitation zone .
Monitoring changes in overall vibration levels over time to establish "normal" baselines and trigger alerts when levels exceed ISO or industrial standards. Common Machinery Faults and Their Signatures Fault Type Frequency Signature Typical Direction Unbalance 1x Turning Speed (TS) Radial (Horizontal/Vertical) Misalignment 1x, 2x, and 3x TS Axial and Radial Mechanical Looseness ½, 1½, 2½, etc. or harmonics Bearing Defects Non-synchronous (BPFO, BPFI) High frequency / Broadband Gear Mesh Issues TS x Number of Teeth Radial and Axial
