-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Fixed Speed Electric Motors driving Centrifugal Compressors are designed considering the pressurized start-up as the most critical condition in terms of the torque requirement. Their capability is checked during the design ...
-
Novel Fiber Optic Technology Monitors In-Slot Vibration and Hot Spots in an Air-Cooled Gas Generator (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Gas-fired and air-cooled generators are subjected to continuous start-stop-load cycles related to thermal/mechanical stresses, and continuous vibration. The machines are designed to run at highly efficient material use and ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This case study discusses the rerate of a set of vertically-mounted singlestage end-suction centrifugal pumps used for low pressure safety injection (LPSI) in a nuclear power plant. The original LPSI pumps were supplied ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)High pressure lean amine pump performance dropped within a span of about 1 month due to internal fouling. Fouling was caused by accumulation of iron sulphide. To address the fouling, pump would have been to taken out of ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)In rotating machinery, squeeze film dampers (SFDs) reduce rotor synchronous response amplitude motions, provide structural isolation and enhance rotordynamic stability. Compared to conventional squirrel cage supported SFDs, ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)In the subsea oil and gas industry, multiphase pumps and wet gas compressors add pressure to the process fluid thus enabling long distance tie back system that eliminates topside facilities such as an oil and gas separation ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Energy efficient operation of fluid film bearings demands savings in delivery flow while also managing to reduce fluid film and pad temperatures. To achieve this goal, tilting pad journal bearings (TPJBs) implement a variety ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Floating ring annular seals are used when large radial rotor displacements must be accommodated. They belong to a larger family of sealing devices that includes face seals and segmented seals. They all use carbon rings and ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)There was a failure in the gear box of the main feed pump of the hydrocracker unit. As no spare was available, there was no immediate fix to the failure. A quick evaluation of the damage to the gear was done and an interim ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 14: Centrifugal compressors are at times required to operate in or near the choke region. Various limits of the degree of allowable operation in choke have been established. Based on test data and numerical data, ...
