Temperature Measurements in Fluid Film Bearings
(Texas A&M University. Turbomachinery Laboratories, 1984)
Temperature measurements have been widely used in the past to monitor the conditions within hydrodynamic journal and thrust bearings. These temperature readings are appreciably affected by changes in the operating conditions ...
New Solutions In The Process Industry - Application Of Six-Stage Integrally Geared Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1987)
At the end of the forties, the integrally geared centrifugal compressor was developed and initially used for air, and later for nitrogen and other gases. To date, about 10,000 units are in use working in the capacity range ...
Retrofitting A Topping Turbine For Performance And Mechanical Improvement.
(Texas A&M University. Turbomachinery Laboratories, 1986)
Current design technology applied to existing rotating equipment can produce significant energy and maintenance dollar savings. The results achieved when a two-stage topping turbine was retrofitted to a three-stage ...
Shop Balancing Of Turbomachinery Rotors.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The details of shop balancing flexible shaft rotors are discussed with an explanation of the key parameters involved, such as tolerances and specifications, balance procedures, and documentation. Understanding and controlling ...
Electric Shaft Currents In Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1987)
Electrical damage to turbomachinery parts has caused a number of machinery failures and many hours of costly downtime. The problem of electrical voltages and currents being generated in non-electrical machines has puzzled ...
Balancing Of Integral Gear-Driven Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1986)
Due to the complex dynamic behavior of gear-driven centrifugal turbocompressors, selection of the proper balancing and assembly procedures is essential to obtain a smoothly running rotor. Rigid and flexible balancing ...
On Steam Solution Of A Prototype 8000 HP Motor Instability Problem.
(Texas A&M University. Turbomachinery Laboratories, 1983)
This paper presents a typical field problem that most maintenance engineers in any petrochemical plant could encounter. Two 4000 hp through-drive electric motors were totally destroyed when the inboard coupling failed. ...
Improving Critical Speed Calculations Using Flexible Bearing Support FRF Compliance Data.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The importance of including flexible supports in rotordynamic analyses is discussed. Various methods of including the support in rotordynamic calculations are reviewed. A method is described in which actual compliance ...
Design And Calculation Methods For High-Speed Gears Of Advanced Technology.
(Texas A&M University. Turbomachinery Laboratories, 1983)
High-speed gears of very high powers and/or very high speeds must be exactly analyzed and optimized in gearing, bearing and housing in order to achieve low noise, low vibration running with maximum safety in operation. The ...
Testing And Startup Experiences With Rotating Equipment At Nation's First Commercial Scale Coal Gasification Plant.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The Great Plains Gasification Plant in Beulah, North Dakota, converts lignite coal to pipeline quality synthetic natural gas (SNG) using high Btu technology. The rotating equipment for this grass root facility presented ...
