Presentation Transcript

  1. SAMPLE SLIDES OF THE 1-DAY SEMINAR FOR PUMP USERS As you will notice there are few words on these slides, your trainer will provide you with his experience which will make these images come alive providing you with the opportunity to reflect and ask questions, the more the better. All of the presentation slides are available in a binder supplied with the seminar.

  2. Pump systems

  3. A BRIEF HISTORY

  4. Pressure is independent of the shape of the reservoirs

  5. Low pressure helps to suspend the fluid

  6. A pump system acts as a reverse siphon

  7. Demo for low pressure at the high point of a piping system

  8. The energy required of the pump

  9. Specific energy or head

  10. The total head or total specific energy required of the pump

  11. Pump performance curves

  12. Vapor pressure

  13. Experiment to boil water at room temperature

  14. Operating principle of a centrifugal pump

  15. Section of a centrifugal pump

  16. Performance curves

  17. NPSH depends on: The elevation of the surface of the suction tank The pressure in the suction tank The friction loss in the suction line The vapor pressure of the fluid at the operating temperature

  18. Selecting the right impeller diameter

  19. Measurements on demo system

  20. 3. Evaluate these situations in terms of good, medium or poor? Ans: _____ Ans : _____ Ans : _____

  21. 4. Give your opinion on the piping layout at the pump suction in terms of good, medium or poor? Ans : _____ Ans : _____

  22. SOLUTION TO THE ELBOW TOO CLOSE TO THE PUMP SUCTION PROBLEM

  23. USING AN EXCENTRIC ELBOW

  24. Pumps in parallel - Instability

  25. Minimum submergence of the pump suction piping

  26. The effect of air (or gas) entrainment in the pump suction

  27. Causes and problems associated with pump systems • • Excessive vibration causing damage to the impeller due to: • - cavitation

  28. Causes and problems associated with pump systems • • NPSH or low pressure at the inlet

  29. Opportunities with higher return

  30. High efficiency motors

  31. Opportunities with higher return
