PT09 - Submersible pump condition monitoring using motor current signature analyses and vibration analyses comparison
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
The paper further shows the real case studies, analyses and findings on Submersible Pumps. The article contrasts the similarities vs. differences and advantages vs. disadvantages of both methods and may be of value for ...
PT05 - Predicting Centrifugal Pump Type and NPSH in Early Facility Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
This tutorial focuses on centrifugal pumps, which are generally the workhorse of industrial oil, gas, and petrochemical facilities, and the tutorial approaches an early assessment concept in several parts. First, it examines ...
CST07 - Blade failure analysis for steam turbines used for driving centrifugal compressors
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
Blade failure was caused by a huge alkaline element of Na flowing into the steam turbine from upstream due to improper water treatment. In this presentation, we will inform the reason why Na precipitated in dry steam ...
CST03 - Part 1: High Reliability Pistons for Reciprocating Compressors in High Wear Situations
(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 ...
CST04 - Radial Subsynchronous Vibration Caused by Axial Vibration
(Turbomachinery LaboratoryTexas A&M Engineering Experiment Station, [2019])
This case study presents a presence of radial subsynchronous vibration during mechanical running tests of High Pressure Compressor following API 617 requirement. During the tests it was investigated how the lateral vibration ...
TL07 - Direct Head Measurments for Turbomachinery Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
The isentropic head is one of the most important physical properties for the design and testing of compressors and turbines. It is a critical parameter for the determination of machinery work and power from test data and ...
TL08 - Addressing High-Subsynchronous Vibrations in a Turboexpander Equipped with Active Magnetic Bearings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
This paper presents the experience of the authors with a turboexpander (TEX) equipped with active magnetic bearings (AMBs) in a natural gas processing facility. The TEX was unable to achieve design performance due to high ...
