The Challenge for the Accurate Determination of the Axial Rotor Thrust in Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 2014)
The axial thrust is basically generated by a pressure imbalance across the impeller. The impeller is subjected to a great force trying to move it against the incoming flow. The cumulative thrust of all impellers on the ...
Manufacturing and Testing Experience with Direct Metal Laser Sintering for Closed Centrifugal Compressor Impellers
(Texas A&M University. Turbomachinery Laboratories, 2014)
Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that utilizes a high-powered laser to build up a metal part by selectively melting thin layers of metal powder. This process is attractive for the ...
Optimization of Swirl Brake Design and Assessment of Its Stabilizing Effect on Compressor Rotordynamic Performance
(Texas A&M University. Turbomachinery Laboratories, 2014)
The rotordynamic stability of high pressure compressors is strongly affected by the aerodynamic effects induced by the gas flow through rotor-stator seals. In particular the tangential velocity (swirl) of the gas flowing ...
Short Course T6: Babbitted Bearing Health Assessment
(Texas A&M University. Turbomachinery Laboratories, 2014)
Materials in Centrifugal Compressor and Steam Turbines: Selection, Processing, and Repair
(Texas A&M University. Turbomachinery Laboratories, 2014)
Gas Bearings and Magnetic Bearings for Oil-Free Rotating Machinery
(Texas A&M University. Turbomachinery Laboratories, 2014)
Gas bearings (GBs) are an efficient alternative for load support of high speed microturbomachinery (< 400 kW, +1000°F, +3M DN). These bearings are compliant surface hydrodynamic bearings using ambient air as the working ...
Advanced Mechanical Seals 201 - Demistifying Piping Plans and Support Systems
(Texas A&M University. Turbomachinery Laboratories, 2014)
The Use Of Air Cooled Heat Exchangers In Mechanical Seal Piping Plans
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
Piping plans provide a formalized approach to enhancing the environment of the mechanical seal. One of the most frequent methods of modifying the seal environment is to reduce the temperature of fluids in the sealing ...
An End-User's Guide To Centrifugal Pump Rotordynamics
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
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 ...
Considerations For Dual Pressurized Gas Seals In Pump Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
Mechanical seals continue to be the predominant technology for shaft sealing in centrifugal pumps and other rotating equipment. While most mechanical seals are designed to operate on a liquid film, there are options for ...
