Abstract: ​​

The seminar is concerned with the detection and analysis of anomalies in the petrochemical plants using an electronic diagnostic expert system. The major objectives were to develop a double air-gap sensor method of detection for petrochemical pump, and to model such a system using an analytical technique. A detailed two-dimensional mathematical and physical model has been used, producing a general expression of the missing electromagnetic field from sensors occupying any radial position in the air-gap of the pump and describing the important physical phenomena occurring on the energy conversion system. Signals were processed and analyzed using FFTA . Finally, considerable attention has been paid to the harmonics present as the detection scheme was used in conjunction with a microprocessor based data acquisition unit for powerful on-line monitoring which examines selected harmonics continuously.
