Gas Turbine Performance And Maintenance
(Texas A&M University. Turbomachinery Laboratories, 2012)
Proper maintenance and operating practices can significantly affect the level of performance degradation and thus, time between repairs or overhauls of a gas turbine. Understanding of performance characteristics of gas ...
Simplified Modal Analysis For The Plant Machinery Engineer
(Texas A&M University. Turbomachinery Laboratories, 2012)
Experimental modal analysis and operating deflection shapes (ODS) are powerful tools in vibration analysis and machinery troubleshooting. However, the machinery plant engineer often doesn’t believe such techniques are ...
Valve Performance And Life Of Reciprocating Compressors
(Texas A&M University. Turbomachinery Laboratories, 2012)
The operation of a reciprocating compressor is closely linked to the performance of its valves in terms of life and efficiency. Most operators report that the most significant cause of forced outages of reciprocating ...
Noise Trouble Shooting on a Variable Speed Planetary Gear Application for Off-Shore Process Gas Compressor
(Texas A&M University. Turbomachinery Laboratories, 2012)
How Important Are The Protection Systems & Valve Design That Can Contribute To The Equipment Integrity On Reciprocating Compressors
(Texas A&M University. Turbomachinery Laboratories, 2012)
Comparison Of Different Variable Speed Compression Train Configurations With Respect To Rotordynamic Stability And Torsional Integrity
(Texas A&M University. Turbomachinery Laboratories, 2012)
Wherever a variable speed gas compression train is needed for Oil & Gas upstream applications as well as for gas storage applications the primary decision has to be made between a gas turbine driver and an electric motor ...
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 ...
Witness Testing Of API 610 Centrifugal Pumps And API 611 Steam Turbines
(Turbomachinery Laboratory, Texas A&M University, 2012)
The tutorial outlines the basic concepts and offers some tips on witness testing of API 610 centrifugal pumps and API 611 steam turbines. The section on API 610 pump testing discusses performance, NPSH and mechanical run ...
Breaking The Cycle Of Pump Repairs
(Turbomachinery Laboratory, Texas A&M University, 2012)
Bearing Maintenance Practices To Ensure Maximum Bearing Life
(Turbomachinery Laboratory, Texas A&M University, 2012)
Reliability of centrifugal pumps is heavily dependent on bearing reliability. The bearings that support the impeller shaft are complex machine components whose service life is directly affected by: Contamination (both ...
