Full Speed String Test On LM6000PF Gas Turbine Driven Refrigeration Compressors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Chevron Australia, as part of the Wheatstone Project, constructed a two train liquefied natural gas (LNG) facility and domestic gas plant at the Ashburton North Strategic Industrial Area, 12 kilometers west of Onslow on ...
Aero-Damping Measurements And Computation In A Full-Scale Multistage Centrifugal Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Great interest is being paid by Oil & Gas industry to the design of high speed and high pressure ratio centrifugal compressors. Static and dynamic stresses are becoming higher and, under critical conditions, aerodynamic ...
Impeller Stall Induced By Reverse Propagation Of Non-Uniform Flow Generated At Return Channel
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
In the case of centrifugal compressors, minor non-uniform flow upstream of the impeller is induced by an asymmetrical configuration in the circumferential direction at the compressor suction casing. This non-uniform flow ...
A Review Of Aerodynamically Induced Forces Acting On Centrifugal Compressors, And Resulting Vibration Characteristics Of Rotors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
There are several sources of non-synchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, ...
Redesign of Centrifugal Compressor Impeller by means of Scalloping
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Impellers of centrifugal compressors may experience resonance with vane passing frequencies, especially when operated away from the design conditions. Resonance can cause a serious structural damage to impeller. Complete ...
Asynchronous Motor - Failure of Rotor Lamination Teeth
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
During full load testing of moto-compressor, abnormal vibration were detected. Failure was observed on electrical motor rotor lamination teeth. Deep experimental analysis and metallurgical investigations revealed a high ...
Improving Reliability and Reducing Steam Leakage in General Purpose Steam Turbines with Floating Brush Seals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This case study examines four different applications where brush seals were introduced into the gland boxes of process steam turbines where conventional carbon rings and mechanical seals were previously applied. The resulting ...
Integral Gear Compressor Gearbox Flooding Issue
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This case study discusses a series of integral gear compressor trips and machine damage that resulted from a sudden increase in motor power not related to process changes.After testing it was determined that the increase ...
Analysis and on-stream countermeasures of sub-synchronous vibration of a centrifugal compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The sub-synchronous vibration could be attributed to many causes such as gas-whirl, oil whirl, looseness and so on. To prevent sub-synchronous vibration, manufacturer analyzes stability during design stage. But field ...
A High Bearing Temperature Troubleshooting of Centrifugal Heat-Pump Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
On September 2013, a centrifugal heat-pump compressor began showing an abnormal temperature rise in its tilting pad journal bearing (DE-side). The phenomenon appeared when increasing the rotor speed following a process of ...
