(Texas A&M University. Turbomachinery Laboratories, 2010)
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Peculiar, low-frequency, radial vibrations have been observed in various turbomachinery using tilt-pad journal bearings. Unlike discrete subsynchronous spikes that often indicate a serious problem, the vibrations are ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)A few well established hydraulic design parameters define the internal quality of an impeller design. Becoming familiar with those parameters and understanding their limits will enable pump buyers to make better pump buying ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)Many facilities do not obtain the expected life out of ANSI and other centrifugal pumps, seals, and bearings that need to be obtained to be competitive in today’s market place. The analysis of this situation leads to two ...

-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Not accounting for detrimental environment factors in the design and environment degradation are two of the most common causes of Turbomachinery component failures. This paper discusses the importance of knowing the operating ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)Condition monitoring data collection capabilities have grown over the last decade in large part due to advances in integrated circuits (IC). These advances now permit real time thermodynamic and process calculations on ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)In the last few years, the installed capacity and production of electricity from all the renewable energies have significantly risen, supported by an ever-increasing spread of new energy policies all around the world. ...
-
(Texas A&M University. Turbomachinery Laboratories, 1981)New applications are being found for adjustable speed drives due to: 1) the availability of high current solid-state devices, 2) a simplified inverter design with large scale integrated circuits (LSI), and 3) because of ...
-
(Texas A&M University. Turbomachinery Laboratories, 1992)Converter-fed adjustable speed electric motors are now finding increasing use for driving turbomachinery in the power range from 1.0 to 20 (50) MW. The most important properties of these drives are explained, with the main ...
-
(Texas A&M University. Gas Turbine Laboratories, 1976)Centrifugal compressors have been used to compress oxygen for at least 25 years. Until ten years ago, the flows were relatively small and discharge pressures were relatively low. In the mid 1960's the size of single train ...
-
(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 ...
-
(Texas A&M University. Turbomachinery Laboratories, 1988)The induction motor has been the work horse of industry for many years. It has achieved this position by virtue of its ruggedness, and relative low cost. Induction motors include the popular squirrel cage and the versatile ...
-
(Texas A&M University. Gas Turbine Laboratories, 1974)The performance of advanced radial inflow (RIF) turbines is reviewed and new results of stress and blade vibration analysis are presented. Due to the development of modern manufacturing techniques, large radial inflow ...

-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)Laser cladding is gaining acceptance for restoration of turbine and compressor shafts, which has resulted in increased customer demand for laser cladding options. This has increased the number of laser welding suppliers, ...
