Vibration Monitoring Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The overall concept of vibration monitoring is presented based upon theory and the practical constraints of machinery construction, transducer characteristics and the cost/benefit ratio of available systems. General features ...
Gas Turbine Control Systems Incorporating Condition Monitoring And Fault Tolerance.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Novel concepts in gas turbine control technology incorporating condition monitoring and fault tolerance are described. Concerns with fault tolerance, system reliability, and users functionalities are discussed. The importance ...
An Independent Refiner's Approach - Practical Solutions To Complex Gear Problems.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Numerous failures and near failures spanning the last quarter century have occurred on a 4000 hp, single induction, double helical speed increaser in hydrogen recycle service. A persistent and unexplainable wear pattern, ...
Retrofitting Turbomachinery With High Performance Flexible Dry Couplings.
(Texas A&M University. Turbomachinery Laboratories, 1990)
When planning maintenance of turbomachinery, the proper selection of dry couplings to replace gear couplings should be considered. The basic criteria used when retrofitting flexible diaphragm or disc couplings is discussed.
Reliability Criteria For Turbine Shaft Based On Coupling Type - Geared To Have Flexibility.
(Texas A&M University. Turbomachinery Laboratories, 1990)
A turbine shaft end at the coupling is exposed not only to constant torque load but to various variable loads as well. These externally imposed variable loads come from sources like compressor surge, misalignment between ...
Recent Case Histories With Coupling Enclosures.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Coupling enclosures are oil-tight guards which serve the double purpose of protecting people from the rotating coupling and returning oil that escapes past the seals back to the oil reservoir. Enclosures were, and still ...
Efficient Part Load Combined Cycle Operation.
(Texas A&M University. Turbomachinery Laboratories, 1990)
During the oil crisis in the 1970s, many electric utilities assigned their base load portion of electric generation requirements to nuclear and coal fired steam plants. The intermediate duty in some cases was assigned to ...
Troubleshooting High Speed Couplings.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Couplings are a major concern of turbo equipment users. Couplings can and do result in many hours of lost sleep for the plant equipment specialists, and can cause failure of equipment resulting in extended periods of ...
Troubleshooting Turbomachinery Problems Using A Statistical Analysis Of Failure Data.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The use of statistical techniques to investigate machinery failure data is one of the most powerful troubleshooting tools available to the turbomachinery engineer. This analysis tool can provide a great deal of information ...
Retrofit, Upgrade, And Demothball Of Two Crentrifugal Compressor Trains.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The design premise in upgrading two operating plants for more compression capability is discussed.
The first is a syn gas plant designed for 1000 tons/day of methanol but converted to syn gas only for a primary acetic ...
