Improvement of Pump/Plant Performance by Sound Evaluation of Both Process Fluid Viscosity Change and Pump Internal Leakage
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
In the modern pump industry, processed fluids are characterized by a wide spectrum of viscosity values. An unpredicted variation of actual process fluid properties, including viscosity, may lead to unexpected pump performance ...
Developing & Testing Components For More Reliable Linear Reciprocating Compression Of Hydrogen
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Southwest Research Institute® (SwRI®), ACI Services, Inc. (ACI), and Libertine FPE Limited collaborated to design and build a Linear Motor Reciprocating Compressor (LMRC) via a DOE-funded project with ACI cost share. The ...
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 ...
