  1. Solar Powered Water Pumping in Senegal Kristen Woznick Andrew Kriebel Ahmed Al Haddad College of Engineering Penn State University 3 December 2012 http://www.practica.org/services/r-d/thermal-solar-pumps/

  2. This presentation covers two yields of the project that is used to provide solar powered water pumping to Senegal Interactive spreadsheet Prototype of a low cost alternative design

  3. A project schedule laid out the steps and timeline for project milestones Research & Background Concept Generation Concept Development Prototyping

  4. The first task was to archive existing solar powered pumps in a searchable database Archive company, model no., lift, output, etc

  5. Started with data base which archives 64 submersible pumps from 9 manufacturers with important criteria Company Model # Input Elec. Max Lift Output @ Max Lift Max Output Lift @ Max Output Weight

  6. What do these input values specify ✓submersible pump ✓head ✓Lift ✓Flow Rate ✓Horsepower

  7. Changes to the database improved functionality with criteria input with the searching function Drop-down menus for the input criteria Macro-enabled “find My Pump” button Output of correct pump that matches the input criteria

  8. Future Considerations We ask: If someone enters a set of requirements that are above one capability, but below another, would you be able to suggest the one that has more than the asked for requirements? 

  9. The second task is to innovate and prototype a solar powered pump to meet the needs of a farm in Senegal 20 cubic meters per day SUN’S ENERGY 1.2 – 1.6 m ENGINE/PUMP ASSEMBLY 20 m CROPS 2 m WATER

  10. Based around a gamma stirling engine, our design was to use the heat of the sun to create the work to drive a pump SOLAR HEAT TO ENGINE GAMMA STIRLING ENGINE SUN IN SOLAR DISH TO CROPS WATER COOLS ENGINE HIGH SPEED LOW TORQUE WORK PULLEY/GEAR LOWER SPEED HIGHER TORQUE WORK PUMP WELL WATER

  11. Using gamma engine models, a Solidworks model was constructed to study the motion Compression Ratios Critical Lengths

  12. A non-walking beam gamma engine was settled upon and modeled as our engine DISPLACER POWER PISTON EXPANSION COMPRESION WORK OUT HEAT COLD

  13. The gamma engine is incorporated into the assembly design with the solar dish, ‘gear’ system, and pump

  14. The gamma engine is incorporated into the assembly design with the solar dish, ‘gear’ system, and pump Solar Collecting Dish Hot End of Engine Cool Side with Water Gamma Engine ‘Gear’ System Water Pipe Mechanical Pump

  15. The gamma engine is incorporated into the assembly design with the solar dish, ‘gear’ system, and pump

  16. The design is easy to assemble, features available materials, and only requires basic machining

  17. The design is easy to assemble, features available materials, and only requires basic machining

  18. The prototype is proof of engine function and pump design, but lacks the torque necessary to function as an assembly ✔ ✔ - X X Gamma Engine Function – Heat to Work Pump Function – Movement of Water Solar Collector Connection Engine to Pump Full Function

  19. To improve performance, it is necessary to make several changes to the design Higher Heat Differential HOT COLD Multiple Cylinders

  20. Small scale prototype led to the development of a Stirling based water pump Interactive pump Database Developed a Concept and a Feasible Design Prototype and Test Concept Future Steps
