The course presents a systematic approach to the basics of mechanical troubleshooting,. It first adopts a general approach to the importance of pumps, bearings maintenance and its main motives, then it explains what is meant by maintenance types, like preventive maintenance, corrective and adaptive maintenance and the skeletons of maintenance systems. Design, operating, and design pumps, bearings will be explained. Measurements, maintenance and the required misruling devices for pumps and bearings will be deeply involved in this course with some applications in other mechanical utilities.

Upon completion of this course, participants will gain also an understanding of basic utilities maintenance like Ammeters, Voltmeters, Wattcmeters, Power factor meters, Oscilloscopes, also they will be aware of troubleshooting problems and the associated actions to be taken, specially in the cases of equipment failure.

1. Electrical, mechanical, and chemical Engineers.
2. Senior technicians who work in the electrical control and power utilities.
3. Technicians who would like to refresh their knowledge.
4. Mechanical and chemical Engineers who are interested in control subjects.
