-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)Progressing cavity pumps develop their pumping action by the meshing of the external threads of the elastomer stator and the internal threads of the metallic rotor. The special geometry, as characterized by the different ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)Destructive overspeeding of steam turbines due to poor component design, inadequate maintenance, and improper operating practices are all too common. The total cost of a turbine runaway can run into the millions of dollars ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)At present, there are no commercially available codes in industry that have proven to reliably predict a rotors sensitivity to the Morton Effect. The Morton Effect refers to synchronous rotor instability due to non-uniform ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)Analytical and experimental studies were carried out on a progressive cavity pump (PCP) fitted with a metallic stator with a fixed, positive clearance around the single helical rotor. This eliminates wear and greatly ...
-
(Texas A&M University. Turbomachinery Laboratories, 1990)Squirrel cage induction motors have been used extensively in industry for over 50 years. While it appears that vibration problems are more pronounced nowadays, certain basic construction features have always existed and ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Accurate predictions of centrifugal pump performance are critical in every fluid industry. Many industries encounter situations where a fluid more viscous than water must be conveyed with a centrifugal pump. As liquid ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)The cause and effects of a large subsynchronous vibration (3.5 mils at 3490 cpm) in an FCC wet gas compressor are examined. The compressor is driven at 7850 rpm by a 6000 hp electric motor, through a speed-increasing ...
-
(Texas A&M University. Gas Turbine Laboratories, 1980)Operating requirements for new fans demand that greater attention be given to the design of the total installation including everything from the foundation to the ducts. Rotor dynamic analysis without adequate consideration ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)
-
(Texas A&M University. Turbomachinery Laboratories, 2010)Unsteady flow field measurements of both static and total pressure, and discharge angle have been carried out downstream of an industrial centrifugal impeller. Phase-resolved measurements were performed using a cylindrical ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Pine Bend, MN, 12x10, 9 stage vertical can pump, 600 hp, 1780 rpm A new smaller, higher efficiency motor was installed to replace the old motor and shortly after numerous mechanical seal failures occurred. The motor ...

-
(Texas A&M University. Turbomachinery Laboratories, 2000)Thermoplastic use a labyrinth seals in rotating equipment is continuing to gain acceptance in the process industries. Presented in this paper is a discussion on thermoplastic use as a labyrinth seal material in centrifugal ...
-
(Turbomachinery Laboratory, Texas A&M University, 2010)Among the technologies developed for oil and gas production centrifugal pump sealing applications, active lift technology is one of the most promising. The reliability of any centrifugal pump in a critical application is ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)Conventional mechanical seals are arranged to prevent leakage from a high pressure source. When leakage occurs, it is expected to be from the high pressure area to the lower pressure surroundings. The basic concept of the ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)Vertical turbine pumps are designed to operate with the pump shafts in tension (downthrust). Most pump and motor manufacturers caution users to not operate the vertical turbine pumps at conditions that result in “upthrust.” ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)Piping plans provide a formalized approach to enhancing the environment of the mechanical seal. One of the most frequent methods of modifying the seal environment is to reduce the temperature of fluids in the sealing ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)Asbestos-free gaskets have been used to seal flanged connections on various applications. This paper discusses the use of a different style of gasket and details the advantages and benefits resulting from such a change. ...
