Vibration analysis is like giving your equipment a check up from the doctor. Vibration is the only tool in a predictive maintenance toolbox that can accurately detect equipment problems like imbalance, misalignment, eccentricity, resonance and looseness that lead to bearing failure. In much the same way a stethoscope is placed on you by a doctor, placing a sensor on the bearings of a piece of equipment like a pump or motor can help maintenance understand its operating condition.
These vibration readings are recorded to monitor and help plan for maintenance repairs.
As these level trend upwards and into alarm the data is then viewed in one of 2 formats- a waveform (which is the raw form of the data) or a spectrum (which is like an end view of the waveform).
For example if the pump had an imbalanced situation the waveform would show a complete cycle in one complete rotation of the shaft.
If this waveform cycle was viewed from the end we could see the once per revolution cycle more clearly. This is called a spectrum and is the primary tool used in equipment failure diagnosis.
