A comparison of Operating Deflection Shape and Motion Amplification Video Techniques for Vibration Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The Operating Deflection Shape (ODS) technique that was derived from Experimental Modal Analysis has served well to assist users in quantifying vibration amplitudes, determining vibration mode shapes, looseness between ...
ANNULAR CLEARANCE GAS SEALS: MODELS AND MEASUREMENTS FOR LEAKAGE, FORCE COEFFICIENTS AND THEIR EFFECT ON ROTOR STABILITY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...
Key Differences between Steam Turbines and Electric Motors as Main Compressor Driver in Olefins Plants
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This study starts by presenting a typical ethylene plant which will act as the ‘base plant’ for this case study. Then, a ‘low�emission’ ethylene plant is introduced which employs a new cracker technology having ...
LASER WELDING FOR TURBOMACHINERY ROTOR RESTORATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Laser cladding is gaining acceptance for restoration of turbine and compressor shafts, which has resulted in increased customer demand for laser cladding options. This has increased the number of laser welding suppliers, ...
MITIGATION OF AXIAL VIBRATION AND THRUST BEARING FAILURES IN ROTATING MACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The objectives of this tutorial are to familiarize rotating machinery engineers involved in detailed engineering and site operation on various aspects of axial vibration in rotating machinery. Among all rotating machines ...
MODERN LUBRICATING OIL SYSTEMS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Lubricating oil systems are vital to operation, long-term reliability, and availability of turbomachinery trains (or strings) which are strategic and expensive components of industrial plants. Sometimes, the entities that ...
MECHANICAL SEALING TECHNOLOGY USED IN MULTIPHASE PUMP APPLICATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
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 ...
Comparison of contacting wet and dry gas seals for main pipeline pumps in NGL services
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Recent incident reports and studies of pipeline equipment indicate that pump seal performance is likely at the root of a significant increase in releases to the environment. Although these releases are small compared to a ...
PNEUMATICALLY ACTUATED CONTROL VALVES IN OIL SYSTEMS: HARDWARE RECOMMENDATIONS AND TUNING CONSIDERATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Well designed and properly commissioned auxiliary systems are crucial to the reliability of rotating equipment. This paper addresses the upfront hardware selection and commissioning of pneumatically actuated control valves ...
AN OVERVIEW OF MACHINERY IN ENERGY STORAGE AND HYDROGEN APPLICATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Decarbonization of electric power infrastructure requires the development of cost-effective, sustainable, and reliable energy storage technologies that are capable of many Megawatts or Gigawatts of output and long storage ...
