Improving Reliability On A Centrifugal Compressor Experiencing Frequent Bearing Failures
(Texas A&M University. Turbomachinery Laboratories, 2012)
A 1957 vintage multi-stage centrifugal compressor, critical in a refrigeration process, had a history of poor reliability and LP stage bearing failures. Around 1995 the HP casing had been replaced and upgraded. In early ...
Load Dependent Critical Speed
(Texas A&M University. Turbomachinery Laboratories, 2010)
Torsional Instability Of Cooling Tower Fan During Induction Motor Startup
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Torsional instability during starting of an induction motor has caused excessive torque oscillation and eventual failure of gearbox pinion teeth of a cooling tower fan train. A torsional instability appeared due to a steep ...
Double Flow Refrigeration Compressor Inlet Piping Design and Analysis
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Objective: • Design an inlet piping system for a double flow centrifugal compressor that effectively utilizes existing site spacing constraints: • Distributes flow to each inlet evenly with minimal pressure loss and without ...
Why Proper Low Pass Filter Settings on Crosshead Vibration Signals are Crucial to Minimize Risk of Missed Detects
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Crosshead guide acceleration measurements have gained mainstream acceptance by operators of API 618 recips and now joins frame velocity as a recommended shutdown parameter in the 5th edition of the API 670 Machinery ...
Development Of Fuel-Flexible Gas Turbine Combustor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Growing global energy demands are motivating the gas turbine industry to seek fuel-flexible gas turbines capable of burning a wide variety of fuels as a means of increasing energy supply stability and security. These ...
New Control Method For Fixed Speed Compressors With Side Stream
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Problem statement: Operability issues were experienced on flash gas back-to-back compressors with lower molecular weight side stream, driven by fixed speed electric motor: • Failed attempts of start-up/loading • During ...
Discussion Group T17 On Advanced Topics in Centrifugal Compressor Design
(Texas A&M University. Turbomachinery Laboratories, 2011)
Discussion Group T14 On Wet and Dry Screw Compressors
(Texas A&M University. Turbomachinery Laboratories, 2011)
Coupling Credible Failure Modes and Owner Options to Intervene
(Texas A&M University. Turbomachinery Laboratories, 2013)
While all machine component failures can impact reliability, cost and production, some like coupling failures may have safety risks for personnel. Intervention requires us to build appropriate steps into our machine and ...
