Design, Testing And Commissioning Of A Synchronous Motor-Gear-Axial Compressor.

LecturePg. 97-112This paper presents the design features involved in providing two air compressor trains at high efficiency. Testing and commissioning data are also presented, including specific electrical requirements; foundation and assembly features; grade maintained air filter designs at 0.5 in. water drop; torsional features not using soft elastomeric couplings; bearing designs for motor, gear and compressors; and test and commissioning data. The test and commissioning data include torsional data, alignment heat rise data, torsional-lateral interaction on run-up, quadrant inlet vane surge tests with flow and vibration responses, eccentricity plots of journals in bearing, transient responses through criticals, and correlations of predicted vs. actual rotor dynamics responses
