820 Theory and Practical Application of Pump Technology
For whom intended This course is intended for personnel involved in specifying, selecting, purchasing or using pumps. Degreed engineers whose primary training is not in this field will benefit, as will technicians, quality assurance inspectors and manufacturing engineers. Course 820 will also benefit managers and supervisors in charge of these functions.
Brief Description of Course The course commences by introducing pump types and parameters, then covers cavitation and hydraulic phenolmena. Centrifugal pumps are covered in detail, followed by pump operation and performance curves, pump operation and mechanical issues and pump seals. The instructor addresses bearing problems, lubrication and failure analysis before moving on to pump imbalance, alignment and coupling.
The presentation then delves into into pump foundations and mountings as well as pumpjacks and blowout preventers. Avoiding pump seal failure and troubleshooting are covered before a detailed unit on maintenance, including predictive maintenance and management. The course concludes with thermography, oil analysis and pump materials.
DIPLOMA PROGRAMS This course is required for TTi’s Piping, Valves and Pump Specialist (PV&PS) Diploma Program. It may be used as an optional course for any TTi specialist diploma program.
