Online Diagnostics Of Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Has the industrial standardization of the IBM PC/ AT as a building block for dedicated instrument computer systems brought costs down to the point where sophisticated monitoring systems are not only possible, but make good ...
Nondestructive Testing of Turbomachinery Components
(Texas A&M University. Turbomachinery Laboratories, 1988)
Nondestructive evaluation is becoming increasingly important in determining the quality of materials and fabrications used in the manufacture and maintenance of rotating machinery. NDE has long been used as a tool for ...
Influence Of Gas Seals On Rotor Stability Of A High Speed Hydrogen Recycle Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1988)
A gas seal retrofit project for a 2800 hp, 10200 rpm, five-stage hydrogen recycle compressor is described. This barrel-type compressor operates with a 1205 psia suction pressure and 1490 psia discharge pressure. The unit ...
Safe Diagram - A Design And Reliability Tool For Turbine Blading.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The complex field of turbine blade vibration has long been in need of improved tools to help predict the reliability of blading. The SAFE interference diagram is presented as such a tool. It presents much more information ...
Vacuum Distillation Methods For Lube Oils Increase Turbomachinery Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The lube oils in self-contained reservoirs for turbomachinery in hydrocarbon processing plants are subject to contamination and deterioration from airborne dust, component debris, system corrosion, heat, and water. Oil ...
Application Of Dry Gas Seals On A High Pressur Hydrogen Recycle Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Maintenance and operation of high pressure seal oil systems on centrifugal compressors has been a major problem faced by refinery operators. This problem is intensified when sealing gases like hydrogen and mixtures of ...
Water Contamination Of Steam Turbine Lube Oils - How To Avoid It.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Ever since steam turbines have been built, contamination of the lube oil by water has been a persistent problem. Water contamination will result in rusting of ferrous components, accelerate sludging leading to sticking of ...
Solution Of Subsynchronous Vibration Problems In Radial Flow High-Speed Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Experience, theoretical and practical, investigations are presented on two radial flow high-speed turbines, which showed unacceptable high subsynchronous vibrations during operation onsite. The first example deals with a ...
Experience With Online Condition Monitoring System.
(Texas A&M University. Turbomachinery Laboratories, 1988)
A total online condition monitoring system has been in operation on the world's largest offshore facility located off the coast of Norway. The Ekofisk platforms are operated by the Phillips Petroleum Company Norway and ...
Turbine Protection System Performance.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The need to protect a turbine generator from abnormal operating condidtions is a given. Power plant operational historical data indicate that malfunction of the turbine protection system (TPS) has been the initiator of ...
