1. Side Entry Agitator Test Stand: P11251 • From left to right: • Dennis Beatty (ME) – Sealing System • Kurt Lutz (ME/PM) – Thrust & Fluid Force Measurement • Daniel Geiyer (ME) – Torque, RPM & DAQ • Richard Kehn – SPX Representative • Bill Nowak – Xerox Team Advisor • Gregory McCarthy (ME) – Shaft, Motor & Impeller • Joe Bunjevac (ME) – Physical Stand The team would like to thank RIT and SPX for making this experience possible. Special thanks to Richard Kehn (SPX sponsor) and Bill Nowak (team advisor).Added thanks to Chuck Guido (Buffalo Custom Canvas), John Wellin, Ryan Crittenden (FMS Electrician), Dave Hathaway, Steve Kosciol, Rob Kraynik, as well as Dr. Kempski & Dr. Bodeo for technical advising. • Introduction • SPX currently has a top entry agitator capable of measuring torque, RPM, axial fluid forces and tangential fluid forces • Industry has a need for a side entry equivalent • Side entry agitators often used in low viscosity blending applications • Significant benefits in large tanks • Used if top accessisnot possible or when the top needs to remain clear for testing • Needs and Specifications • Measure axial and tangential fluid forces • Measure shaft RPM • Measure shaft torque • Vertical translation distance of 10 inches • Horizontal angle displacement of +/- 20 degrees • Vertical angle displacement of +/- 10 degrees • System Design • Base Plate fixed to floor with four concrete anchors • Curved slot with bronze guides adjusts horizontal angle • Horizontal angle virtual pivot point at tank wall for easier adjustments • Multiple bolt points to fix secondary horizontal plate in place • Four lead screws move main assembly vertically • Slots in rear support mounting point allows for vertical tilt • Analog scales allow for quick estimation of setup position • Motor capable of 1800RPM • Mechanical seal reduces torque loss • Flexible seal allows for assembly to move • Impeller fixed on shaft end via set screw • Two dimensional axis load cell position measures thrust and moment forces • Torque calculated through electric motor • Labview interface controls system and records data • Theory/Analysis/Model/Testing • Shaft’s factor of safety designed to be 1.7 assuming worst possible case • Critical Speed designed to be 2,500 RPM to prevent reaching natural frequency • Load cell mounting plate designed for minimal deflection, less than 0.001 inches • Stand’s factor of safety designed to be 4 to prevent fatigue and failure • Results/Conclusions • Testing to be conducted weeks 9-10 • Adjustability Test • Integration Test • Calibration Test • Dry Static Test • Dry Dynamic Test • Wet Static Test • Wet Dynamic Test • Repeatability Test
