THE USE OF ACOUSTIC COMB FILTERS TO AVOID CENTRIFUGAL COMPRESSOR DISCHARGE BLADE-PASS PULSATION INDUCED PIPING VIBRATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Centrifugal compressor blade-pass interaction periodic pulsation can cause acoustic resonance conditions and pipe vibrations in the suction and discharge lines of the compressor. A series of two or more progressively placed ...
PNEUMATICALLY ACTUATED CONTROL VALVES IN OIL SYSTEMS: HARDWARE RECOMMENDATIONS AND TUNING CONSIDERATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Well designed and properly commissioned auxiliary systems are crucial to the reliability of rotating equipment. This paper addresses the upfront hardware selection and commissioning of pneumatically actuated control valves ...
L03: High Speed Balancing: API Acceptance Criteria, Pedestal Dynamics, and Unbalance Response Correlation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Acceptance criteria for high-speed balancing of turbomachinery are specified in API standards based on either pedestal velocity or shaft displacement, and these are discussed in detail Pedestal velocities are measured using ...
