(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 10: Main air compressors used for air separation units (ASU) applications have a suction at ambient conditions and deliver air to a pressure range between 5.6 ~ 6.5 bara. Therefore, the performances of the compressor ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)When unbalance induced vibrations exceed allowable limits, a more accurate system balance is required. If performed at site on assembled machines, it is commonly called field balance. Key point of the activity is the ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Case Study 17: This case study deals with a 25MW turbo-generator train with a semi-rigid connection between generator and gearbox. For this application, machine alignment and connection is a key factor for a smooth ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Electrostatic discharge (ESD) can cause catastrophic mechanical damage and lower the life span of an asset if not detected early and rectified. Continuous discharge of static electricity can cause micro pitting of bearing ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Case Study 6: A 25MW gas turbine had been damaged during operation. Particularly, its tilting pad journal bearings and shaft journals had suffered complete wiping‐out and deep crack damages, respectively. For an emergency ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Two (2) gas turbine engines operating offshore experienced Domestic Object Damage (DOD) failure with damaged blades in the HP compressor section. The failures were caused by repeated use of a component undergoing wear ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 3: 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 ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Case Study 16: 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 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Blade fouling is a relevant problem in turbomachinery applications. It affects both compressors and turbines. In the first case, fouling can be generated by the presence of dust, ashes or brackish air (in offshore ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 12: Closed centrifugal compressor impellers have been manufactured using several methods through the years. Due to limitations of the materials and machining processes, most of these impellers have been manufactured ...
