Plunger Pump Station Vibration-Induced Cracks in Piping
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Many plunger pumps are installed without adequate pulsation and vibration considerations at the design stage. Pressure
pulsations from normal pump operating can cause high shaking forces throughout the entire piping system. ...
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 ...
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 ...
