(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 14
High Vibration Problem Resolution in Centrifugal Pump through Design Change
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 4: The case study is about single stage API BB2 pump. Pump operates at the temperature of 355 degree C (671 degree F), rated for pumping 442 m3/hr of Hydro-treated VGO (Vacuum Gas Oil) and is driven by a steam ...
Case Study on Remote Diagnostics in Resolving Random Vibration on a Steam Turbine
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 7: This case study narrates an incident of random vibration spikes which occurred in year 2014 on one of the steam turbine bearings of a propane refrigeration compressor train. The random vibration spikes caused ...
New Solutions In The Process Industry - Application Of Six-Stage Integrally Geared Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1987)
At the end of the forties, the integrally geared centrifugal compressor was developed and initially used for air, and later for nitrogen and other gases. To date, about 10,000 units are in use working in the capacity range ...
Squeeze Film Dampers: An Experimental Appraisal of Their Dynamic Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 15: Squeeze Film Dampers (SFDs) are effective means to ameliorate rotor vibration amplitudes and to suppress instabilities in rotor-bearing systems. A SFD is not an off-the-shelf mechanical element but tailored to ...
Retrofitting A Topping Turbine For Performance And Mechanical Improvement.
(Texas A&M University. Turbomachinery Laboratories, 1986)
Current design technology applied to existing rotating equipment can produce significant energy and maintenance dollar savings. The results achieved when a two-stage topping turbine was retrofitted to a three-stage ...
Shop Balancing Of Turbomachinery Rotors.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The details of shop balancing flexible shaft rotors are discussed with an explanation of the key parameters involved, such as tolerances and specifications, balance procedures, and documentation. Understanding and controlling ...
Meeting Compression Train Base Package Design Requirements for Service on Floating Production Storage and Offloading Vessels
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
