A Review of the Critical Design Parameters for Labyrinth Type Separation Seals on Dry-gas-seals
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
An ethylene compressor experienced a dry-gas-seal (DGS) hang-up condition and a RCA concluded that a possible root- or contributing cause is lube oil passing the labyrinth type separation seal into the secondary DGS cavity, ...
Gas Seal Failures Caused by Axial Vibrations
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study describes the root cause investigation of 12 dry gas seal failures in three integrally geared centrifugal compressors over a period of 12 years. These compressors are in fuel gas booster service, supplying ...
Analysis and Countermeasures for Sideband of Gear Mesh Frequency(GMF) Induced by Shaft Fretting Corrosion in a Gearbox
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
CS deals with trouble shooting and solving a chronic fretting corrosion damage b/w a gear and shaft (shrink fit). The damage on the geared shaft always accompanied by an increase in the amplitude and frequency side bands ...
Steam Turbine with 0.9X Vibrations
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This 15 MW steam turbine/gearbox/4-pole generator train, following a recent overhaul, was showing unusual phenomenon of high level 0.9X vibration during shutdown, as well as power limits due to vibration level increase. ...
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 ...
