Specifying Steam And Rating Conditions For Special Purpose Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The data required by turbine vendors to properly develop a design for a special purpose steam turbine are discussed in detail. Topics covered include discussion of continuous steam conditions, turbine power ratings and ...
Gear Coupling Misalignment Induced Forces And Their Effects On Machinery Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Gear couplings can produce large static forces and moments that can affect the vibrations of turbomachinery, even with nearly perfect alignment. Research, testing and case histories have verified this theory and are reported. ...
Axial Air Compressors - Maintaining Peak Efficiency.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Axial air compressors have seen increased service in various applications over the years, mainly because of the axial compressor's high operating efficiency, which can be 85 to 90 plus percent. The design of the aerodynamic ...
Large Converter-Fed Adjustable Speed AC Drives For Turbomachines.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Converter-fed adjustable speed electric motors are now finding increasing use for driving turbomachinery in the power range from 1.0 to 20 (50) MW. The most important properties of these drives are explained, with the main ...
A Flexible Pad Bearing System For A High Speed Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 1992)
The application of a new radial and thrust bearing for use in high speed integrally geared centrifugal compressors is presented. The bearing design is of the flexible pad type. Bearing design analyses were conducted to ...
Temporary Repair Of A Large Axial Blast Furnace Motor-Blower As A Solution For A Steel Mill Operational Continuity.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The repair work of a large axial blower that had its rotor and stator blades severely damaged is described. The 43 MW axial air blower is of critical importance for a large steel mill in Brazil, and the repair time was of ...
Applying The Probabilistic Fitness-For-Service Concept For Assessing Reliability Of Weld Repaired Steam Turbine Rotors.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The cost savings and fast turnaround offered by weld repair of turbomachinery rotors results in significant advantages to the end user when faced with the possibility of having to replace the rotor. However, it also carries ...
An Experience With Nonstandard Coupling Application.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The selection of flexible couplings is often considered to be routine because there are a variety of proven designs available. A compressor retrofit that required variance from standard coupling design practice is discussed, ...
