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
