DIAGNOSIS OF SCREW PUMP FLOW INSTABILITY FROM CASING VIBRATION – A HOLISTIC MACHINERY DIAGNOSTIC APPROACH.
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This paper discusses the diagnosis, further analysis and resolution of abnormally high vibration and noise detected on Lube Oil (LO) screw pumps A & B supplying a Turbo Expander Compressor (TEC). During the initial ...
Installation of a Stall Ring to Mitigate Boiler Feed Water Pump NPSH3 Requirements at Low Flow
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
An ubiquitous multistage boiler feed water pump for a SMR Hydrogen Plant in a refinery was specified to meet feed water requirements at plant design hydrogen capacity and at a turndown rate. During testing, it was discovered ...

Vibration Field Problem Resolved with Analytical Diagnostic Approach and Innovative Impeller Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Several pumps of same design exhibited field vibrations above API limits, dominated by Vane Passage Frequency (VPF). Root cause analysis included both experimental and theoretical paths.Experimental investigation , with ...
Whats inside the ‘box’ when considering API Piping Plan 54?
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
API Piping Plan 54 utilizes an external source to provide a clean pressurized barrier fluid to a dual pressurized mechanical seal designed to allow minimal leakage across the primary sealing interface into the process ...
Precision Grouting of Turbomachinery
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Rotating equipment being installed in industrial environments, including refineries and chemical processing plants, are critically aligned with exact tolerances. When in operation, this equipment experiences heavy dynamic ...
Methods to Determine and Specify Rotodynamic Pump Dynamic Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Vibration caused by resonance is an industry problem for new and retrofit applications that persists due to lack of specification and upfront analysis. To limit the chances of resonant vibration, dynamic analysis of the ...
Commissioning A New Multiphase Pump Visualization Test Rig To Investigate The Internal Flow Field And Its Connection With Pump Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Pumps with helico-axial impellers are used to boost mixtures of gas and liquid, for instance in subsea production of unprocessed oil and gas. Experimental data is essential to fully understand and characterize the internal ...
A Novel Approach to Installation of New Crude Bottoms Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Metallurgy upgrades for high TAN crudes and existing NPSH problems required the installation of two (2) new Atmospheric Towers and two (2) new Vacuum Tower Bottoms Pumps. • The new pumps are 450 HP and 1800 rpm versus ...
