(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Operating speeds of multistage pumps tended to increase during the last decade from 4000 to 6000 rpm to 7000 to 10000 rpm, due to new super critical powerplant designs and new conversion processes in the hydrocarbon industry. ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Active magnetic bearings (AMBs) are a mature bearing technology that is being applied to many new turbomachines. They have become the bearing of choice for most new turboexpander applications. They are seen as a key enabling ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)The American Petroleum Institute (API) has recently implemented new rotordynamic stability specifications for centrifugal compressors. The specifications consist of a Level I analysis that approximates the destabilizing ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)At present, the majority factor limiting the designer’s ability to predict the rotordynamic behavior of multistage centrifugal pumps is the availability of accurate input data for the forces acting on the rotor. Recent ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)This paper presents the rotordynamic characteristics of a vertical submerged hydraulic turbine generator obtained during design, manufacturing, shop testing, and site testing. The hydraulic turbine represents a new design ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Balance piston seals restrict leakage at the discharge side of single shaft centrifugal compressors. There are multiple types of annular seals including labyrinth seals, textured surface seals such as honeycomb seals and ...
-
(Texas A&M University. Turbomachinery Laboratories, 1985)Straightforward mechanics are used to give a physical understanding of the important parameters involved in rotor dynamic instability. A concise analysis procedure is proposed for assembling available information into a ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)Full-load, full-pressure rotordynamic stability measurements were conducted on a seven-stage, back-to-back centrifugal compressor. To validate rotordynamic predictions, the rotor was excited while operating at full load ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)Extensive stability measurements were performed during the full-load, full-pressure factory testing of a five-stage inline centrifugal compressor. The compressor, tested up to a maximum discharge pressure of 655 bar (9,500 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)As speed and power density increase, open (unshrouded) impellers are becoming more and more utilized in process gas compressors. Open impellers enable higher tip speeds and more aerodynamic head per stage than closed ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)This paper describes extensive measurements on high-pressure radial compressors with rated discharge pressures of more than 400 bar (5800 psi). The purpose of the measurements was to deterine m the damping behavior of the ...
