Principles Of Operation And Performance Estimation Of Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Case Studies In Turbomachinery Operation And Maintenance Using Condition Monitoring.
(Texas A&M University. Turbomachinery Laboratories, 1993)
With exceedingly high downtime costs and the need for efficient operation of turbo machinery, integrated condition monitoring, wherein a number of health parameters are analyzed, is becoming increasingly popular in process ...
Magnetic Bearing Retrofit Of A High Speed, Eight Stage Coker Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The design, integration, and implementation of a successful project to retrofit a high speed, eight stage centrifugal compressor with magnetic bearings and gas face seals is presented. The application is removal of light ...
Critical Speeds And The Importance Of Stiffness - A Case Study In The Design And Testing Of A Large Mechanical Drive Steam Turbine To API Standard 612.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Rotordynamics has long been one of the major considerations in the design of variable speed rotating equipment. Bearing support stiffness is a significant factor in the designer's ability to predict critical speeds and ...
Analysis Of Torsional Vibrations In Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Predicting And Verifying Rerated Compressor Performance Through Single Stage Scale Model And Limited Field Testing.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Performance verification of centrifugal compressor rerates creates a unique challenge to turbomachinery users. It is not often practical to perform flange-to-flange performance tests on machinery already installed in the ...
Hydraulic Removal Of Coupling Hubs - Keyed And Keyless.
(Texas A&M University. Turbomachinery Laboratories, 1993)
In rotating machinery, torque is transmitted from shafts to coupling hubs (or vice versa) through keys, friction, or a combination of the two. As a rule; coupling hubs must be installed on shafts with a certain amount of ...
Test Of Process Turbocompressors Without CFC Gasses.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Increasing restrictions from environmental protection laws will necessitate at least partial substitution of chlorofluorocarbon (CFC) gases still in use today for performance tests of turbocompressors in closed loops. The ...
Large Motor Installation And Startup.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The installation tasks and startup considerations necessary to commission large electric motors are discussed. The tasks are discussed in the usual installation sequence, but some series of tasks may need repetition if the ...
Baseline Mapping Of Discontinuities Through Nondestructive Testing.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Manufacturers in the compressor industry have experienced an increasing interest by their customers to be able to compare the as manufactured condition of critical components to their subsequent condition over time in ...
