P09454: Design and Testing of Centrifugal Pump Components

1. 2008-2 through 2008-3 P09454: Design and Testing of Centrifugal Pump Components

2. Introduction • Particle Imaging Velocimetry (PIV) uses a sheet laser beam to illuminate particles that cross the sheet. • The particles will diffract the light of the laser and thereby allow for imaging. • Based on the data gathered from imaging these particles, the flow through the system can be visualized.

3. Starting Point • The existing test system was developed for MSD in 2007 -2 & 2007-3 quarters under P08453 • The system consisted of a centrifugal pump that sits within an automated and instrumented flow loop. • The apparatus and pump housing will be fabricated from optically clear materials to allow flow visualization within the pump using Particle Imaging Velocimetry • The system was designed and built with a modular construction so that design variations of impellers, diffusers, and housings may be easily exchanged.

4. Planning

5. Customer Needs • Perform PIV experiments to characterize different flows through the pump system • Use as an teaching tool for undergraduate coursework, projects & labs • Use for Graduate research & projects

6. Deliverables • Design & manufacture interchangeable Impellers & Diffusers (3 items each) • Set up & perform PIV measurement on pump system using new Impellers & Diffusers

7. Mission Statement The purpose of this project is to design & develop interchangeable impellers and diffusers which will work on the existing PIV system in order to characterize different flows through the pump system. Team will deliver 3 impellers & 3 diffusers for the existing system. Furthermore, team will also be responsible for setting up experiments and performing PIV reading using the new impellers & diffusers

8. Constraints • Budget: • Technical Expertise: Not all KGCOE ME students possess the requisite knowledge in Turbomachinery • Time: All deliverables must be performed within the allotted 22 week timeframe • Resources: Impeller and diffuser manufacturing requires precision machining operation • Platform: The project must build upon the existing PIV system (P08453)

9. Assumptions • All roles planned this quarter will be filled during both quarters • Existing test stand can be used and improved for this year’s project • Existing test stand is in acceptable condition • Outsourcing the manufacture of Impellers and Diffusers will not adversely effect the timeliness of the deliverables

10. Work Breakdown Structure

12. Intellectual Property Considerations • Project will be open source, open architecture • Thorough patent research must be carried out prior to starting design phase

13. Team Values & Norms • Punctual • Thorough • Accurate • Professional & Ethical • Committed • Good Communication

14. Team Values & Norms • Punctual • Thorough • Accurate • Professional & Ethical • Committed • Good Communication – • Team members should make a conscious effort to keep all members in the team informed with new information, knowledge and project developments, especially the two leaders

15. Required Resources • Technical learning materials such as Turbomachinery text books, research papers • Access to existing (P08453) PIV pump system • Time with Faculty Guide, Dr. Day • Access to manufacturing resources: CNC machining, Rapid prototyping or outsourcing • CAD & Engineering software packages • EDGE

16. Concept Development

17. Customer Needs • Customers require a upgraded PIV system to perform reading on more sophisticated flow patterns provided by new impellers & diffusers. The new impellers and diffusers must be interchangeable and must fit with the existing pump system.

18. Brainstorming Questions • How can the team best familiarize themselves with turbomachinery concepts? • What material can be used to make the impellers & diffusers? • Which manufacturing method will be used to make the products?

19. Risk Assessment • Technical expertise of ME student might be inadequate for the design task at hand • Time needed for impeller manufacturing will affect the timeliness of deliverables • Existing PIV module may not function as desired

20. Risk Assessment • Flow parameters are not met by the design • Design stage leaks over allocated time due to complications • Manufacturing resources at RIT might be inadequate to produce the required parts • Budget might be insufficient to cover outsourcing of manufacturing

21. Risk Management • Team Lead, Lead Engineer will work with faculty advisor to develop a plan to learn the technical skills required to design turbomachinary • Team lead will look for alternative manufacturing methods to save time, cost ex: rapid prototyping, outsourcing

22. Risk Management • Lead engineer designs a study plan with the assistance of faculty advisor & consultants to learn the required skills • Project lead allocates excess time for manufacturing parts & reallocate labor & resources to expedite other processes.

23. Risk Management • Lead engineer assigns a plan and adequate labor to ensure that the existing will meet required levels of operation • Lead Engineer will reevaluate and prioritize design goals to ensure timeliness of deliverables

24. Risk Management • Lead engineer will reevaluate design to ensure that products can be manufactured using resources at RIT (while meeting specifications) OR • Project Lead and Lead Engineer will work towards outsourcing the manufacturing to outside vendors

25. Risk Management • Project Lead will work with Faculty Advisor to reevaluate the budget OR • Reevaluate the scope of the deliverable to meet the existing budget
