Vibration Analysis is used to detect early precursors to machine failures, allowing machinery to be repaired or replaced before an expensive failure occurs. The vibration analysis is a very important technique. It is based on the high information content provided by the machine vibration signals that are an indicator of a machine condition, used for the diagnosis of faults. Vibration analysis is widely used for detection and monitoring incipient and severe parts, like bearings, shafts, couplings, rotors, motors, etc. Some problems that are usually detected by vibration analysis are unbalance, misalignment, bent shaft, rolling bearing faults, eccentricity, resonance, looseness, rotor rub, fluid film bearing instabilities, gear faults, belt/sheave problems.
Six cost benefits of vibration analysis:
•Reduces equipment costs
•Reduces labor costs
•Reduces lost production time
•Increases efficiency of employee time
