Turbomachinery Laboratory (2009)
(Texas A&M University. Turbomachinery Laboratories, 2009)
Founded in 1971, the faculty and staff of the Turbomachinery Laboratory (TL) and Texas A&M University continue to address the needs of the pump and turbomachinery industries. We are proud to continue Texas A&M’s land-grant ...
Preface to the Proceedings of the 38th Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 2009)
Prevention Of Torsional Vibration Problems In Reciprocating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Torsional vibration problems continue to occur in reciprocating engine and compressor installation. This is due in part to the fact that reciprocating equipment can produce significantly more torsional excitation than ...
Selection Of Materials And Material Related Processes For Fcc Power Recovery Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Fluid catalytic cracking (FCC) power recovery turbines have been in existence for over 50 years and through the year many changes have been made to design, materials, and material related processes. This paper highlights ...
Intermittent Spikes On Vibration And Motor Current Caused By Water Carryover On The Third Stage Of A Centrifugal Air Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Dry Screw Compressor Performance And Application Range.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Screw compressors have the advantage of low mechanical vibration levels similar to those found in centrifugal compressors due their rotary motion. However, screw compressors are positive displacement machines with a working ...
Turbine Overspeed Systems And Required Response Times.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Turbine overspeed events lead to the most dangerous and costly of catastrophic turbine failures. Traditionally, overspeed protection systems were designed and provided by the original equipment manufacturers (OEMs) - few ...
Torsional-Lateral Coupled Vibration Of Centrifugal Compressor System At Interharmonic Frequencies Related To Control Loop Frequencies In Voltage Source Inverter.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Centrifugal compressor train in a refinery experienced high vibration problem due to torsional resonance. Sidebands in the VFD output current based on VFD control loop frequencies were identified as the root cause. In this ...
Steam Turbine Pipe Strain Case Study.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
Repeated Failures On Second Stage Impeller Linked To Blade Natural Frequency Excitation.
(Texas A&M University. Turbomachinery Laboratories, 2009)
