Maximum Efficiency for High Head Process Pumps –Optimizing Side Channel Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Side channel pumps provide high pressure at relatively low flow rates. This comes along with a quite low specific speed and thus with the known disadvantage of a quite poor maximum efficiency.
This paper describes the ...
Crude Oil Non-Pusher Secondary Seal
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Crude oil pipeline pumps traditionally suffer from seal leakage due to the fretting or wearing of the dynamic O-ring. A new concept secondary seal has been developed to eliminate this fretting occurrence. All major seal ...
Cooling Water Pump Station Optimization Using CFD and Physical Model Test
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this paper, a combined study between Computational Fluid Dynamics (CFD) and a model test has been carried on a Cooling Water Pumping Station as part of a new power plant. The aim of this work was to validate a water pit ...
Further Evaluation of the Modified Affinity Laws for the Prediction of Viscosity Effect on the Pump Head Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The aforementioned abstract was accepted in the ASME Journal of Fluid Engineering and may cause copyright issues. The author wishes to submit this abstract and will get us a manuscript by May 1st if approved by the committee.
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 ...
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 ...
