Large Vibrations on a Centrifugal Compressor Caused by High Windage Heating on a Flexible Coupling–Root Cause Analysis and Solutions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Background: 2 parallel trains consisting of a Low Pressure (LPC) and High Pressure (HPC) compressors were supplied for an offshore reinjection application near the coast of Angola. During the commissioning on site large ...
THE INFLUENCE OF THERMAL LOADING ON THE LEAK TIGHTNESS BEHAVIOUR OF HORIZONTALLY SPLIT CENTRIFUGAL COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
For the purpose of maintenance requirements or for some applications in the chemical industry (for instance chlorine) the centrifugal compressor must be designed with a horizontally (axially) split casing.
Beyond the ...
THE CHALLENGE FOR THE ACCURATE DETERMINATION OF THE AXIAL ROTOR THRUST IN CENTRIFUGAL COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The axial thrust is basically generated by a pressure imbalance across the impeller. The impeller is subjected to a great force trying to move it against the incoming flow. The cumulative thrust of all impellers on the ...
Large Vibrations on Centrifugal Compressor Caused by Inappropriate Operation During Mechanical Running Test
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During the mechanical test of a centrifugal compressor, the rotor experienced a sudden increase of the radial vibrations. After re-start, the compressor showed unacceptably high vibrations.
The RCA revealed: The vibrations ...
Blade Failure on an Axial Compressor Caused by Unexpected Operating at Choke
