MSD II –Managerial Presentation Spring 2009 P09454: Design & Testing of Centrifugal Pump Components

Design Team: Rishitha Dias - ISE – Project Manager Kevin Klucher - ME – Lead Engineer John Hayles - ME Reme Meck - ME Ammar Jangbarwala - ME

Project Background: Project Family: Sustainable Technologies for the Global Marketplace Project Track: Flow Visualization Sponsor: Dresser-Rand Corp. Faculty Guide: Dr. S. Day

Project Deliverable: The goal of the project is to design, build, test and deliver to KGCOE, a centrifugal pump system for particle imaging velocimetry (PIV) studies, which can be used both as a teaching tool for undergraduate students as well as a research tool for graduate and faculty researchers.

Customer Needs: Primary Customers:  Faculty & Graduate Researchers  Undergraduate Instructors Customer Needs / Target Specifications:  Generate Multiple Flows~ 3 Unique Impeller Designs ~ 2 Unique Diffuser Designs  PIV Compatibility>85% Transmissivity of Pump Components  Lab Teaching Tool< 5 min Component Swap Time > 0.45” Tool Clearance Measureable Flow, Pressure & Power. Parts must withstand a drop from 42”

Schedule: Product development Phase Current Stage of Design Phase 1 Phase 2 Phase 3 Phase 4 MSD I MSD II Planning Concept Development System Level Design Testing & Refinement

Schedule: Project is on Schedule  Component Manufacture Complete  Pump Assembly Complete  Flow Testing Complete  Documentation Complete

 Characterize Various Flows  5 Impellers & 2 Diffusers available to generate curves  Interchangeable Components  Assembly/Disassembly averages 3.5 minutes Performance:  Measure Pressure, RPM & Flow  Built into GUI functionality  Control Flow, RPM, Pressure  GUI Controls & Valves  PIV Compatible  Clear Acrylic Components

Results:

Test Results As head rises, the flow decreases, demonstrating basic pump curve relationships. With the addition of a vaned diffuser, the head generated is increased versus flat ring diffusers.

Discussion Pump provides 10x the options (impeller and diffuser) with 65% faster component switch time Head generated is up to 60% greater than previous system benchmarks Flow rate is not up to maximum theoretical value of 22.3 gpm. However, ~ 25% increase over previous iteration Diffuser made a large difference in the amount of head generated, up to a 27% increase for the basic 102 impeller New designs can be rapid prototyped and tested in the test loop within several days based on standard dimensions used for the components
