Analysis and on-stream countermeasures of sub-synchronous vibration of a centrifugal compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The sub-synchronous vibration could be attributed to many causes such as gas-whirl, oil whirl, looseness and so on. To prevent sub-synchronous vibration, manufacturer analyzes stability during design stage. But field ...
A High Bearing Temperature Troubleshooting of Centrifugal Heat-Pump Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
On September 2013, a centrifugal heat-pump compressor began showing an abnormal temperature rise in its tilting pad journal bearing (DE-side). The phenomenon appeared when increasing the rotor speed following a process of ...
Sub-Synchronous Vibration on Centrifugal Compressor with Tilt-Pad Bearings
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This presentation provides a success story that sub- synchronous vibration was eliminated on a centrifugal compressor. The sub-synchronous vibration originally occurred at high operational speed on this 5-stage hydrogen ...
Continuous Control of Lube Oil Water Contamination - Never get Surprised Again
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Problem: High water contamination of lube oil damaged a turbine driven process blower on multiple occasions. Traditional solution:• Monitor oil for milky appearance – only qualitative • Drain free water from reservoir, but ...
Resolving Cyclic Vibration on an Instrument Air Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Instrument Air Compressors are considered critical equipment in the plants, supplying compressed air to the instrumentations in the field. This case study focuses on cyclic vibration phenomena observed in the 2nd and 3rd ...
