CST13 - Manifestations of Thermal Imbalance in Integrally Geared Compressors
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
Three case studies showing 3 different manifestations of thermally induced bow/ imbalance in integrally geared machine are presented
TL11 - Numerical and Experimental Analysis of Flow-induced Subsynchronous Vibrations in Integrally Geared Turboexpanders
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Turboexpanders are widely used as energy recovery systems, in plants where a stream of pressurized gas is available as output of the main process. The train is typically composed of a single or multi-stage radial inflow ...
CST05 - Fluid-Film Bearing Damage Detection Based on Vibration Data�
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
This case occurred during startup after outage on a steam turbine generator. Vibration reached over full scale of 20 mil pp at generator drive end bearing and therefore tripped the unit. The major vibration component that ...
CST06 - Influence of Bearing Selection on MTBF (Mean Time Between Failure) of a Screw Expander in Geothermal Power Generation Service
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
A geothermal power producer located in New Mexico, USA operates four screw expanders, each rated nominally at 1,000 kW. Chronic, extremely short expander life manifested through catastrophic bearing failure has significantly ...
CST03 - Part 2: High Reliability Pistons for Reciprocating Compressors ? Non Lube Piston for 5 Year Run-Time�
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
Reliability and performance related issues of pistons and cylinder rings can be avoided in the vast majority of cases and the piston should never be the MTBF (Mean Time Before Failure) bottle neck. Even for non-lube machines ...
PT08 - Midstream Pipeline Applications � Design Aspects and Considerations for Mechanical Seals
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
There are few applications that place a significant demand on mechanical seals such as those associated with the handling of various fluids through pipelines. Pipeline applications are unique in that they typically encompass ...
PT06 - Transforming Condition Monitoring into effective Condition Based Maintenance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
It is clearly understood by most Maintenance and Reliability professionals that a Condition Monitoring program should identify faults ahead of failures, allowing time for scheduling of remedial works and the management of ...
PT03 - Understanding Waterhammer in Pupmping Systems and Surge Supression Options
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Waterhammer in pumping systems is an area of frequent concern to designers and operators. Waterhammer has the potential to cause catastrophic failures if not properly addressed. System designers have multiple options to ...
PT10 - Precision Grouting of Turbomachinery
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Rotating equipment being installed in industrial environments, including refineries and chemical processing plants, are critically aligned with exact tolerances. When in operation, this equipment experiences heavy dynamic ...
PL03 - Realistic Expectations from a Unique Plan 66A Bushing Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
The 66A dual bushing arrangement is used to provide leak detection on crude oil pipeline pumps. Here the effectiveness of the arrangement in detecting seal leakage and providing leakage containment are examined through ...
