Vibration Analysis of Gas Turbine’s Transportation Carrigage and Warranty Issues
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper describes the investigation of whether the vibration shock limits were exceeded on the transportation of 2 gas turbines. This investigation was requested due to an improper suspension type of the carriage used ...
Applying Upstream Pumping Sealing Technology for high corrosive fluid – Improve Reliability & Operating Cost
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This is a mechanical seal upgrade case study about applying advanced upstream pumping technology instead ofconventional tandem seal arrangements with external flushing in high corrosive fluid pump seal applications in order ...
Rotor Magnetization in Turboexpander and its Effect on Vibration Readings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A magnetized rotating machine behaves like an electrical generator. It often produces localized stray current that usually discharges across small clearance paths imposing damage to machine internals and vibration probes. ...

Investigation and Resolution of Governing Valve Linkage Failure for Compressor Drive Steam Turbine
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Fatigue failure of Governing Valve Linkage Rod end bearing and wear marks on several parts was observed on a extraction steam turbine (driving a centrifugal compressor) after it was in service for more than 9 year. The top ...
Glycol-Based Lube Oil Behavior & Its Effects In Fuel Gas Compression System
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Oil-flooded screw compressors (2 units x 100% duty) deliver fuel gas from AGRU Absorber at saturated condition to GTG to sustain oil production facilities @ ~33 MW power demand. Each Fuel Gas Compressor (FGC) is rated for ...
Mechanical (Liquid) Seals: General (Installation, Operation, Troubleshooting, and Retrofitting)
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Mechanical seals are the most common method of sealing industrial centrifugal pumps and other rotary equipment. Although the
basic concepts of a seals are simple, successfully using seals requires an understanding of the ...
