Reliability And Future Development Of High Pressure Diaphragm Pumps For Process Service
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
The aim of pump development in recent years has been mainly reliability, safety, low maintenance, and the avoidance of dangerous leakages. For years, more and more rigid regulations against pollution and for better safety ...
Pump Baseplate Installation And Grouting
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Methods used by the author to level and epoxy grout pump baseplates. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Execution of the leveling ...
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 ...
A New Computer Program For Pump Rotordynamic Analysis
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A new computer program for pump rotor analysis has been developed to improve the accuracy of critical speed, stability, and response calculations for multistaging centrifugal pumps. The program capabilities include: (1) ...
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 ...
