NPSHR (NPSH3) IMPROVEMENT OF A LOW PRESSURE SAFETY INJECTION PUMP
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study discusses the rerate of a set of vertically-mounted singlestage end-suction centrifugal pumps used for low pressure safety injection (LPSI) in a nuclear power plant. The original LPSI pumps were supplied ...
Large Cooling Water Pump Upgrade for Increased Capacity And Reduced Impeller Cavitation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study discusses the hydraulic upgrade of two sets of four (25 percent) large vertical cooling water pumps. To increase the electrical output of subject power station, the cooling water pumps of block 1 and 2 had ...
Pump Cavitation -- Physics, Prediction, Control, Troubleshooting
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This short course gives insight into roto-dynamic pump cavitation and provides deeper understanding of particulars like cavitation inception, three-percent head drop, 40,000 hours life criterion, cavitation damage potential, ...
