P14474: Hydrostatic Test Apparatus Jake Manley Anushka Kalicharan Mitchell Sedore Brian Benner Kyle Abbott
Project Overview Goals • Control pressure, ramp rate, and time • Test enclosures against UL1203, UL2225, and CSA 22.2 no. 30 • Control test automatically with minimal operator interaction Constraints: • Must reuse current fixed displacement pump • 10,000 psi max pressure • Ability to capture results during test • Future Labview Integration
Customer Requirements Top Customer Requirements • Test Automation complies with Standards • Ability to Interface with Current Cooper Product Line • Ability to Acquire Data from Test • Complete Apparatus for On-Site Testing • Control of Pressure, Hold Time, and Ramp Rate
Engineering Requirements Top Engineering Requirements • Deliver Maximum Required Pressure to Enclosure • Withstand Maximum Internal System Pressure • Deliver Minimum Required Pressure to Enclosure • Pressure Ramp Rate • Hold Time for 4X Max Internal Explosion Pressure • Hold Time for 1.5X Max Internal Explosion Pressure
Alternatives Considered • Hold Components: Manifold vs. Inline • Data Transmission: Wired vs. Wireless • Test Control: Hybrid (Digital and Manual) vs. Strictly Digital.
Manifold vs. Inline Design for Holding Components Manifold • Pro’s • Compact, single unit • Less plumbing connections • Less opportunities for leakage • Con’s • Large manifold • Difficult to manufacture • Less flexibility in component placement Inline • Pro’s • Flexible location of components • Small components • Easy to manufacture • Con’s • More parts and connections
Wired vs. Wireless Method for Data Transmission Wired • Pro’s • Simple • Reliable • Inexpensive • Secure • Con’s • Requires Physical Routing • Possible Data loss due to Wire Damage Wireless • Pro’s • Easy to add Components • Con’s • Expensive • Less Secure • Susceptible to Interference
Hybrid vs. Strictly Digital Manner of Test Control Hybrid • Pro’s • Fail-Safe • Full Automation • Allows for Manual Override • Con’s • More Components • More Complexity Strictly Digital • Pro’s • More Compact • Full Automation • Con’s • No Backup System
Risk Analysis Highest Risk
Testing Plan • Pressure Sensor(s) • Apply varying pressures to sensor(s) to verify output matches expected values. • Calibrate sensor(s) as necessary. • Structural Integrity of Piping and Hose. • Perform calculations to determine approximate pressure for conduit failure. • Simulate stress experienced by conduit with finite element model if deemed necessary from calculations.
Testing Plan • System Controller • Simulate logic before programming the controller to debug as necessary. • Apply stimulus to controller to recreate input from pressure sensor and observe output waveforms to verify functionality. • Pressure Control System • Apply stimuli to pressure controller to simulate input from test controller to verify functionality and response time. • Attach to test controller and apply stimuli to controller. • This simulates input from pressure sensor and can be used to verify reaction time and functionality of pressure controller.
What is a Hydrostatic Test? • Tests structural integrity of the product • Product: Electrical enclosures • Simulates explosion within the electrical enclosure • High Pressure Tests : • Proof Test • Hold time at specified pressure • Destructive Test • Test to failure • Determines safety factor (UL Standards)
Standards • UL1203 • Electrical enclosure: 10 sec hold time without rupture • Safety factor of 4x internal explosion pressure • UL2225 • Cable sealing: 10 sec hold time w/o rupture • Safety factor of 4x internal explosion pressure • Pressure: 100-600psi/min • CSA22.2 no.30
Current Hydrostatic Test Apparatus • Fully functional • Manually controlled by technicians • Analog pressure and time measurements • Isolated Test Environment • Follows standards: • UL1203 • UL2225 • CSA22.2 no.30
Project Deliverables • Hardware • Complete onsite test apparatus • Documentation • Maintenance Recommendations • Model for fatigue predictions • User guide for operation • Engineering Drawings
