Surge Exploration Tests and Second Quadrant Characteristic Dynamic Modeling on Full-Scale Centrifugal Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Surge exploration tests on a full-scale centrifugal compressor have been performed allowing an evaluation of the transient behavior and the mechanical robustness of the compressor even during a critical event such as Surge. ...
Fundamentals of Centrifugal Pump and System Interaction
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Are you confused by the variety of pumps? Know how to properly size pumps?
Did you know that proper pump selection can reduce maintenance & energy costs?
Do you understand what causes cavitation in pumps and how it can ...
Optimizing Pumping Systems with Proven Engineering Assessment Processes and Methodologies
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
When pump systems are not optimized for best efficiency, they drain corporate profits with higher energy and maintenance costs, shorten mean time between repairs and increase CO2 emissions. Optimized pump systems are more ...
Differences In Piping System Design for Reciprocating and Centrifugal Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Reciprocating pump installations require particular design considerations which are much different from centrifugal pump systems. An incomplete design basis for reciprocating pump installations can lead to costly remedial ...
Vibration Problems and Solutions in Pumps and Turbomachinery
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This course presents analysis and testing methods for pumps and turbomachinery. Focus is on centrifugal pumps of all types, centrifugal compressors, axial compressors, fans, steam turbines and gas turbines. Rotordynamics ...
Troubleshooting of Sub-synchronous Torsional Interaction Phenomena on an Electric Motor-Driven Centrifugal Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study discusses the identification, troubleshooting, and correction of a torsional instability in an electric motor-driven driveline with variable frequency drive (VFD) for a high-pressure gas compressor test ...
Investigating & Improving the Drooping Curve of a Two-Stage Feed Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A two-stage feed pump exhibited a drooping head-flow characteristic during its shop test. Impeller reworks were done to improve the drooping curve. CFD study was performed to examine the pump flow behaviour and a more ...
Correction of High Vibration on a Vertical Turbine Deep Well Pump with a Dynamic Vibration Absorber
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A 100 horsepower, 180 foot deep vertical turbine pump called #12 Well Pump had a history of reoccurring high vibration despite multiple pump rebuilds and motor replacements. The problem was identified as a structural ...
Improved Reliability of Waste Water Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This is a case study for a chronic waste water unit pumps failures. The impact of the failures were severe due to the significant cost of maintenance (130K USD on average) which was taking place twice a year. The pump ...
Pumps 101
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This course is aimed at technical professionals who need a broad-based introduction to basic pump selection, application and operation. This course starts with the basics and builds to provide a full understanding of ...
