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 ...
Refrigeration Compressor Basics For The Oil And Gas Industries
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This tutorial discusses the design basics for refrigeration compressors, using the 2�section Propane refrigeration configuration as an example. The benefits of incorporating a flash gas Economizer are discussed, as are ...
An End-User's Guide to Centrifugal Pump Rotordynamics
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This tutorial outlines the basics of pump rotordynamics in a form that is intended to be Machinery End User friendly. Key concepts will be defined in understandable terms, and analysis and testing options will be presented ...
High Temperature Sealing Advancements Utilizing Non-Contacting Gas Seal Technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Non-contacting dual pressurized gas lubricated seals for use in pumps have been in service since the early 1990’s. The application of these seal designs has expanded over time into very high temperature applications up to ...
Performance Of Industrial Gas turbines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Industrial gas turbines have performance characteristics that distinctly depend on ambient and operating conditions. Application of these gas turbines, as well as the control and condition monitoring, require to consider ...
Visualization Of Oil-Water Emulsion Formation In A Centrifugal Pump Stage
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Electrical submersible pumps are assembled in oil wells to act as artificial lift methods. When water is present in the reservoir, oil-water emulsions are formed in the pump. These two-phase mixtures affect the performance ...
