Bicoherence Analysis of Tailing Pump Vibration Data at Suncor
Enayet Halim, PhD student in Chemical Engineering
Supervisor - Dr. Sirish Shah
The vibration signal carries the signature of faults in most rotating equipments, and early fault detection is possible by analyzing the signal using different signal processing techniques. Faults in pumps, usually wears in pump impellers, leave their signature on the vibration signal and generally manifest themselves as a non-linear transformation in the signal. Bicoherence analysis detects and quantifies the presence of non-linearity in the signal and thus indicates the severity of the fault in the pump.
