    Root Cause Analysis Of A Long Term Reliability Problem With Reciprocating Compressors In H2 Service. 

    Drosjack, Michael J.; O'Neill, Philip E.; Lorio, Dale V. (Texas A&M University. Turbomachinery Laboratories, 1998)
    Three large reciprocating compressors in H2 makeup service had been a chronic reliability problem for 30 years. Unit revisions greatly compounded this issue by eliminating builtin spare capacity. A Root Cause Analysis ...

    Squeeze Film Damper Bearing Experimental Vs Analytical Results For Various Damper Configurations. 

    Kuzdzal, Mark J.; Hustak, Jerry F. (Texas A&M University. Turbomachinery Laboratories, 1996)
    Higher speeds, longer shafts, and increased power has made squeeze film damper (SFD) bearing performance increasingly more important to control both synchronous and subsynchronous fibration in rotating machinery. SFD bearing ...

    Application Of A Heat Barrier Sleeve To Prevent Synchronous Rotor Instability. 

    Jongh, Frits M. De; Hoeven, Pieter Van Der (Texas A&M University. Turbomachinery Laboratories, 1998)
    This paper explains how synchronous rotor instability can occur in high speed turbomachinery due to differential heating of bearing journals. Theoretical investigations have indicated that rotors supported by fluid-film ...

    Turbine Instability Solution-Honeycomb Seals. 

    Armstrong, Jay; Perricone, Frank (Texas A&M University. Turbomachinery Laboratories, 1996)
    A 40,000 hp steam turbine-generator in a utility service experienced a history of high vibration alarms and trips from an online vibration monitoring system. The excursions of high vibration restricted the operational load ...

    The Design, Application, And Operation Of High Efficiency Turboexpanders In Process Plants. 

    Kardine, William A.; Agahi, Reza R.; Ershaghi, Behrooz; Zeidan, Fouad Y. (Texas A&M University. Turbomachinery Laboratories, 1996)
    Turboexpander thermal efficiency is an important parameter in the process design of hydrogen purification plants. When a process requires low flow and high head, expander thermal efficiency can only be improved by increasing ...

    Design And Retrofit Of A Low Solidity Diffuser For A Pipeline Centrifugal Gas Compressor Application. 

    Flathers, Michael B. (Texas A&M University. Turbomachinery Laboratories, 1997)
    A high efficiency, single-stage pipeline centrifugal gas compressor, originally designed with a wedge-type vaned diffuser, was retrofitted with a vaneless diffuser along with two low solidity diffuser configurations in ...

    Vibration Reduction Or Large Steam Turbine Generator Through Bearing Analysis/Modification. 

    Spencer, Joseph W.; Osborne, Don (Texas A&M University. Turbomachinery Laboratories, 1997)
    Large utility steam turbines have experienced very high vibration levels on their generator exciter bearings. Units where the exciter rotor is supported by a single bearing are particularly susceptible. This synchronous ...

    Discovering, The Hard Way, How A High Performance Coupling Influenced The Critical Speeds And Bearing Loading Of An Overhung Radial Compressor - A Case History. 

    Corcoran, Joseph P.; Rea, Harvey; Cornejo, Guill A.; Leonhard, Martin L. (Texas A&M University. Turbomachinery Laboratories, 1997)
    A case is presented where significant unacceptable vibration levels were encountered during mechanical testing of a single stage overhung radial compressor used in a mechanical vapor recompression process. The contract ...

    Turbine Remanufacture - One Option For Reliability And Efficiency Improvement. 

    Johns, David A.; Rasmussen, David; Beverly, James (Texas A&M University. Turbomachinery Laboratories, 1997)
    A case study of a remanufacture of a steam turbine is presented. The turbine has been in service for 20 years. Thermal and physical stresses have taken their toll on the turbine casing and supporting hardware. Remanufacture ...
