Case Study On Coupling Crack On A Centrifugal Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This case study is focused on accurately identifying the root cause of the observed change in the rotor natural frequency by analyzing the vibration excursions on a motor driving a centrifugal pump through a flexible ...
Repair and Protection of Pump Foundation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
While we go to great efforts to properly set rotating equipment, often consideration is not made to protect the base, and foundation system from erosion or corrosion. In this case study severe erosion of the foundation ...
Measurement And Calculation Of A Self-Equalized Tilting-Pad Thrust Bearing Under Static Misalignment
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Tilting-pad thrust bearings which include a self-equalizing feature, ensure reliable and safe operation especially under conditions on which misalignment between bearing and collar occurs. One common method to incorporate ...
Ethylene Product Pump Mechanical Seal Design Enhancements through Advanced Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
One of the largest ethylene and polyethylene production complexes in the world located in Alberta Canada was dealing with marginal reliability of the mechanical seals on their ethylene product pumps. The ethylene product ...
An Objective Way To Account For Unbalance Vibration In Measured Rotor-Dynamic Data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This paper will illustrate a practical, objective and general method to calculate the unbalance and runout part of measured rotor-dynamic vibration data by a statistical method. Vibration measurements, as typically recorded ...
Thermo-Structural Analysis Of Steam Tracing Arrangements Applied To Pump Barrels
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Pumps steam tracing is widely used in Oil&Gas industry for critical services in which the process fluid requires a minimum temperature to avoid its crystallization during stand-by. This paper describes the process of ...
L12: Effect of Flow Rate on the Performance of a Flooded-Ends Tilting-Pad Journal Bearing Experiments and Predictions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Rotating machinery relies on engineered tilting-pad journal bearings (TPJB) to provide static load support with minimal drag power losses, relatively low pad temperatures, and ensuring a rotor dynamic stable operation End ...
L08: Performance Test of Full-Size Wet Tolerant Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Standard centrifugal compressors (CC) are designed to process dry gas or gas mixed with negligible amount of liquid Significantliquid content, namely liquid mass fraction (LMF) up to 30%, yield to rapid mechanical deterioration ...
T02: Mechanical Sealing Technology used in Multiphase Pump Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Multiphase Pumps have demonstrated their capability to operate successfully in pumping the product extremes, means 100%liquid up to 100% gas, as well as solids This duty is difficult for a pump and thus even more difficult ...
L02: Rotordynamic Analysis and Testing on an Integrally-Geared Compressor Serving a Hydrogen Recovery Application
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
The paper examines the case of a rotordynamic analysis and subsequent rotodynamic testing conducted during the pre-order phase for a five-stage integrally-geared centrifugal compressor, which today is operating in a refinery ...
