(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)During commissioning of a new 8-stage CO₂ pipeline compressor, higher than expected seal vent flows were detected from the carbon ring seals in the high pressure (HP) stages. The problem was severe enough that the machine ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)This case study is focused on accurately identifying the root cause of the observed change in the rotor natural frequency by analyzing the vibration excursions on a motor driving a centrifugal pump through a flexible ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)During the independent Asset Integrity Review (i-AIR) audit conducted on one of the offshore production facility, use of instrument air as separation medium for separation seal of the process gas booster compressors Dry ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)History gets confusing. A lot of emails, vibration reports, and attempted fixes over the years. Customer spent 3 years working closely with OEM, Pump was shipped back to OEM for additional testing. OEM design suggestions ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)Cavitation performance improvement of an industrial cryogenic pump is studied in this paper. A variable pitch helical inducer is designed and implemented to the existing pump assembly to enhance the cavitation performance ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)Cavitation is a phenomenon that is of great concern to both the design and operation of pumps. The presence of cavitation – that is, the formation of vapor bubbles in the flowing fluid that subsequently collapses – can ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)The detailed sizing and selection of centrifugal compressors may be somewhat of a mystery to the typical user.
