5. Safely convert compressor from 6 to 2 stages Safely install compressor Create a functional interface to log and trend data 1 4 32 1 – Installation and interface relate via the installation of a suitable computer workstation 2 – Interface and revamp relate through the documents both sub functions will produce for future teams to use 3 – Revamp and installation are related through the creation of a safe environment suitable for the revamp of the compressor 4 – All sub-functions work together to provide a safe, solid, and functional foundation for future teams to pursue further revamp and fault detection projects Relationships of Sub-functions

7. Safety Considerations Vibration shutoff switch –due to excessive vibrations Emergency kill switch –2 e-stops to ensure safe exit from room Lock-out Tag-out Panel –Prevent electrocution and pinch hazards Safety equipment –Eye, Ear, Hand and Foot Protection Fire Hazards –2 fire extinguishers for ABCD type fires Signage –Warnings, Hazards, and Exits Clearly marked Vibration-Monitoring Switch

8. Concept Description: Installation Test Cell Layout Installation procedure and preparations Boulter Rigging Corporation: Used to transport and place machine Necessary Supplies: Storage Rack, Workbench, Desk, Tools, Tool Chest Top View of Test Cell with Components and Locations Section A-A: Basement view of Test Cell and Compressor Position

9. 12X Primary design intent: Reduce amount of vibrations transferred to floor and surrounding building Maintain machine position Distribute weight on floor 12 Heavy duty spring mounts are to mounted along he perimeter of the machine using existing mounting holes. Concrete anchors will attach the mounts to the floor. Spring Mount Specifications Highest vibration isolation from floor (Need 5.4 Reduce Vibs Impact) High deflection if needed to absorb serve vibrations (Need 3.4 Scale Down Vibs) Distributes weight to 12 21in^2 areas on floor (Need 1.2 Safety, Structural) High weight capacity (13200lbs) (Need 1.2 Safety, Structural) Anchoring to floor (Need 1.1 Safety, Install) Reasonable Price and Labor Concept Description: Mounting

10. Concept Description: Revamp Power –Reduced to 25 HP (Calculated) Electrical –37.5 Amps (Calculated) Cooling –17°F  T in Open Loop Cooling (Fresh Water) –Exhaust Considerations

11. Concept Description: Interface System to acquire and trend data from the compressor –Temperature –Pressure –Flow –Crank angle –Vibration –Valve timing LabView chosen as program to interconnect interface and DAQ DAQ device will be purchased from National Instruments

12. Concept Design of Interface Initial design Measurements organized by stage and type Includes options to change sampling time, save files

13. High Risk Assessment Mitigated –Sound (D-R Data, Dissipation Experiment) –Vibration (Spring-Action Damping Mounts) –Budget (Coordination between D-R and RIT) Remaining –Structural Load (Consultant Lead Time) –Formula SAE Team (Exit Test Cell 09-2329)

14. Current State of Design Designs meet all customer needs Designs meet engineering specifications except for: –Structural load capabilities not confirmed On target to meet project budget pending: –Costs for Electrician and Structural Consultant Schedule: –Only possible issue is compressor arrival due to consultant lead time Mitigations: –Environmental effects from machine (Heating and Sound) –Lifting and access specifications for motor removal
