BEARING LOAD ANALYSIS OF RECIPROCATING PISTON COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Many problems in today’s industrial environment require smart modeling assumptions in order to make them numerically accessible with an acceptable amount of effort. This case study shows how a field problem (main bearing ...
High Speed Coupling Failure related to Torsional Vibration
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This case study presents compressor high speed coupling failure where torsional natural frequency is excited. The case study examines a repeat high speed coupling failure that excited 2�ᵈ torsional natural frequency ...
Detection of Broken Blade on Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A sudden step change in vibration was observed on a 7400 rpm compressor with direct amplitude from 43 um pp to over 62 um pp (trip level) at NDE, thus tripping the unit Vibration reached over 120 um pp at 4000 rpm, compared ...
Case Study on Investigation and Resolution of High Lube Oil Pump Bearing Temperature for Off Spec. Condensate Recycle Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Off Spec Condensate Recycle Pumps on an onshore gas production facility exhibited high lube oil temperature in pump bearing housing that exceeded the alert limits since commissioning. A Structured Root Cause Analysis was ...
Application of Polycrystalline Diamond (PCD) Bearing for Reactor Circulation Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The axial flow loop reactor pump installed in a polymer unit facilitates slurry circulation in the reactor. The pump is installed with triple mechanical seal having API seal flushing plans 32, 53C and 52. The seal cartridge ...
Implementation of Voted Flame Detectors to Prevent Spurious Fire Detection in Gas Turbines Enclosures.
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Fire detection inside Gas Turbine enclosures is a safety critical component to prevent unwanted consequences should a fire occur within the enclosure. The standard design and implementation strategy remains by and large ...
PITTING CORROSION LED TO CATASTROPHIC GAS TURBINE COMPRESSOR BLADE LIBERATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A gas turbine's intake system usually has 3 4 stages of filtration After the primary and secondary filter, the final marine vane separator ( is used These filters are designed to keep rainwater debris, and salt from entering ...
HIGH SPEED PUMP: MECHANICAL SEAL BAD ACTOR RESOLUTION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Case study include a vertical pump in sour water service running at high speed of 17200rpm. Pump originally equipped with single seal & Plan 21 configuration since day one. In 2018, as part of a reliability upgrade, seal ...
Wet Refrigeration Screw Compressor Failure due to Liquid Slugging
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A wet screw refrigeration compressor had three failures and all failures were related to male rotor High- High axial displacement. The failure was concluded to be due to liquid propane formation at compressor suction, ...
