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 ...
Power Turbine Field And Shop Balance Experience
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A power turbine (PT) experienced a high 1X vibration issue. Balancing was attempted at two accessible planes on the shaft section. However, the unit could only operate with vibration below the alarm level in steady-state ...
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 ...
Transforming Maintenance Using Virtual Assembly
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Virtual assembly is challenging historical maintenance paradigms by reducing durations up to 75%, while improving quality and safety. Turbomachinery can be virtually assembled to identify and address assembly issues prior ...
Reciprocating Compressor Motor Vibration During Initial Start-up
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Shortly after start-up of a new 4 throw 3 stage reciprocating compressor, high motor vibration was recorded on a machinery monitoring system. The single bearing motor vibration levels reached 260 microns (10.25 mils) during ...
Annular Clearance Gas Seals In The 21st Century: A REVIEW OF THE EXPERIMENTAL RECORD ON LEAKAGE AND DYNAMIC FORCE COEFFICIENTS, INCLUDING COMPARISONS OF MODEL PREDICTIONS TO TEST DATA
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...
Centrifugal Compressor Configuration, Selection And Arrangement: A User's Perspective
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The detailed sizing and selection of centrifugal compressors may be somewhat of a mystery to the typical user. Once the suction and discharge process conditions and required flow rates are established, they are submitted ...
Materials And Coatings For Turbomachinery In Hydrogen Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Centrifugal compressors are commonly utilized for hydrogen compression in refineries for critical applications, and a potential “Hydrogen Economy� to lowering the carbon footprint on a worldwide scale will require ...
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 ...
