Pump Tut - WHY MACHINES FAIL TO FOLLOW TEXTBOOK STATED RULES, AS ILLUSTRATED BY SHAFT CRACK AND ROTOR SELF EXCITED VIBRATION CASES IN CRITICAL MACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This tutorial demonstrates some aspects of rotating machinery diagnostics where there is an apparent difference between the actual response of a machine and its expected behavior for a certain type of malfunction as typically ...
Self excited torsional vibration in single shaft combined cycle turbine-generator train
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case history describes the investigation of the source of unstable behavior of a newly commissioned single-shaft, combined cycle, power generator unit. The source was found to be nonlinear operation of the flexible ...
How to detect Electrostatic discharge (ESD) using proximity probes on rotating machines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In this session, a brief introduction about electrostatic discharge phenomena will be done. Then three historical cases with Electrostatic Discharge (ESD) issue will be analyzed in order to explain how to detect Electrostatic ...
