Flow Induced Vibration Problem During Full Load Testing Of A Multi-Stage Centrifugal Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During FAT of a centrifugal compressor, non-synchronous vibrations were observed. The dominant frequencies are
different from both a) the rotor system natural frequency, and b) typical rotating stall frequency in parallel ...
On the Performance of Tilting Pad Bearings: A Novel Model for Lubricant Mixing at Oil Feed Ports with Improved Estimation of Pads’ Inlet Temperature and Its Validation Against Experimental Data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Energy efficient operation of fluid film bearings demands savings in delivery flow while also managing to reduce fluid film and
pad temperatures. To achieve this goal, tilting pad journal bearings (TPJBs) implement a variety ...
Application of Dynamic pressure-balanced Seals in a Multi-stage Centrifugal Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Test results for an ASME Power Test Code 10 (PTC) Type 1 test of a 4,500 psia (310 Bara) discharge pressure gas lift centrifugal
compressor outfitted with dynamic pressure-balanced seals at the impeller eyes; shaft interstage ...
Development, Testing and Qualification of Innovative Low Viscosity Oil In Turbomachinery Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The continued market demand to have more efficient machines, thus achieving energy savings and emission reductions, has motivated manufacturers to look for improvements even in area that have never been explored and evaluated ...
Industrial IoT Brings Benefits and Opportunities for Rotating Equipment Suppliers and Plant Operators
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The evolution of the Industrial Internet of Things
(Industrial IoT) and the increasing availability and
affordability of constituent technologies such as sensors,
gateways, networks, platforms, and analytics brings with ...
Dry Gas Seal (DGS) Separation Seal Failure
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study presents the failures experienced on separation seals installed on several compressors. The failures resulted in oil migration to the dry gas seals.
Segmented contact-type carbon ring bushing separation ...
Catastrophic Failure Diagnosis with Modal Analysis of Generator Endwindings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This failure lead a root cause analysis and a series of investigations that was taken place in a similar design unit deployed at a different site. This paper will describe the bump test and modal analysis procedures and ...
Couplings and Rotating Machines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This course covers the design and application of high performance couplings and
rotating machines. Initially the Turbomachinery driver and driven machines are
analysed together with their characteristics and how they affect ...
Case Study on Resolving High Vibration Issue of a Centrifugal Compressor at an Offshore Platform
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Gas Injection Compressors are critical for offshore oil production facilities. A compressor downtime lowers oil production. This case study is about a Gas Injection Compression train at an offshore platform in the Middle ...
Save your Centrifugal Machinery during Commissioning
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During the commissioning of centrifugal machines (Compressors, steam turbines, pumps, fans etc.), a lack of flushing, inspection and ignorance of critical areas & procedures can lead to major problems, damage, and serious ...
