Whalen, John K.; Allen, Jim; Hess, Thomas D.; Craighton, Jack (Texas A&M University. Turbomachinery Laboratories, 2012)Within most plants there is often a desire to extend the time between outages. Several factors determine this but one to consider is the bearings ability to run for the extended time. This Tutorial will address common ...

Leader, Malcolm E.; Whalen, John K.; Grey, Godfrey G.; Hess, Thomas D. (Texas A&M University. Turbomachinery Laboratories, 1995)A critical multistage steam turbine in a large chemical plant experienced high vibration levels and frequent repairs. Numerous failures occurred while passing through the rotor's first critical speed including heavy rubs. ...

Whalen, John K.; Krieser, Skip (Texas A&M University. Turbomachinery Laboratories, 1998)Many pieces of rotating equipment experience oil leaks. Any piece of equipment with oil fed bearings, such as turbines, motors, gearboxes, and compressors, are susceptible to oil leaks from the bearing case seals. Usually ...

Nicholas, John C.; Whalen, John K.; Franklin, Sean D. (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 ...

Smith, Patrick J.; Obeid, Victor; Benton, Robert E, Jr.; Whalen, John K. (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Centrifugal compressors and steam turbines commonly use hydrodynamic journal bearings. These bearings can be fixed geometry (sleeve) or tilting pad type. Most end users expect bearings to operate trouble free from major ...

Whalen, John K.; Leader, Malcolm E. (Texas A&M University. Turbomachinery Laboratories, 2003)A new cogeneration installation was in the process of being commissioned when severe subsynchronous vibration was detected on the generator during no load tests. Subsequently, two rotordynamics problems were discovered. ...

Whalen, John K.; Alvarez, Eduardo (Ed); Palliser, Lester P. (Texas A&M University. Turbomachinery Laboratories, 2004)For over 15 years now, the efficiency and reliability of centrifugal compressors have been enhanced by the application of thermoplastic materials to the eye, shaft, and balance piston labyrinth seals. Traditionally these ...

Whalen, John K.; Dugas, John R. (Texas A&M University. Turbomachinery Laboratories, 2000)Thermoplastic use a labyrinth seals in rotating equipment is continuing to gain acceptance in the process industries. Presented in this paper is a discussion on thermoplastic use as a labyrinth seal material in centrifugal ...
