Novel Fiber Optic Technology Monitors In-Slot Vibration and Hot Spots in an Air-Cooled Gas Generator
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Gas-fired and air-cooled generators are subjected to continuous start-stop-load cycles related to thermal/mechanical stresses, and continuous vibration. The machines are designed to run at highly efficient material use and ...
Natural Frequency Whirl Instability in an Industrial Gas Turbine
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Following failure and in-situ replacement of Bearing 1 on a two-shaft 70 MW industrial gas turbine, excessive vibration was observed on Bearing 2 a few months later.
This case study describes the vibration symptoms and ...
Turbine Basic Knowledge of Steam Turbine Short Course, ST?101/201 Combined
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
It is shown as the outline in this short course that the role of steam turbine, history,
classification, basic structure, components and their function, manufacturing and design
process and control system. And also, the ...
Effective Procedure for Turbomachinery Field Balance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
When unbalance induced vibrations exceed allowable limits, a more accurate system balance is
required. If performed at site on assembled machines, it is commonly called field balance.
Key point of the activity is the ...
Materials in Centrifugal Compressor and Steam Turbines: Selection, Processing, and Repair
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Materials selection is significant with respect to performance, reliability, and longevity of
turbomachinery, particularly given the increasing severity of the process environments. The trends are
that the selection is ...
