Who Should Attend?
This course is intended for all Engineers and technical staff involved in centrifugal and positive displacement pump operation, maintenance or engineering.
Course Outlines:
Hydrodynamics Applied to a Pumping System
Pump Performance
- Flow in a pump, velocities triangle, internal flow, and energy losses
- Theoretical and practical head: characteristic curve
- Other characteristics: efficiency, power, NPSH required
- Changes in characteristics vs. rotation, viscosity, impeller shape, cavitation
Pipe System
- Liquid flows in pipes: friction losses
- System curve, the resistance of flow and throttling control
- Operating point: normal and maximum capacities, change in fluid characteristics and incidence on operating conditions
- Case study: the study of a reflux line and its pump
CENTRIFUGAL PUMP TECHNOLOGY AND SELECTION
