-
(Texas A&M University. Gas Turbine Laboratories, 1979)Annular clearance spaces, such as impeller wearing rings, inter0stage bushes and balance drums in centrifugal pumps, or the fluid-filled clearance around the armature of the submerged motor, at a first glance present the ...
-
(Turbomachinery Laboratory, Texas A&M University, 2011)
-
(Texas A&M University. Turbomachinery Laboratories, 1986)The influence of high pressure bushing-type oil seals on the rotordynamic characteristics of a centrifugal gas compressor, which compresses hydrogen from 1700 psi to 1800 psi is discussed. The compressor rotor is driven ...

(Texas A&M University. Turbomachinery Laboratories, 2007)
-
(Texas A&M University. Turbomachinery Laboratories, 2009)Mixed operation with both centrifugal and reciprocating compressors in a compression plant poses significant operational challenges as pressure pulsations and machine mismatches lead to centrifugal compressors’ instabilities ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)Growing attention has focused on the need to increase meantime between failure (MTBF) for pumps used in the chemical process and refinery industries. Increasingly, discussion has centered on mechanical seals and the benefits ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)For a centrifugal slurry pump to accurately match a pipeline system, it is necessary to know how the presence of solids will affect the pump performance. If accurate corrections are not made, it is likely that the pump and ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)Compared to leading edge technologies such as high speed turbomachinery, reciprocating pumps may appear to be a simple technology: A reciprocating plunger causes liquid to be drawn from a low pressure manifold through the ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)Many of the mechanical drive steam turbines in service in the world today were designed without the demands for optimum efficiency. In order to meet the changing economic requirements that plants face, technological solutions ...
-
(Texas A&M University. Gas Turbine Laboratories, 1976)With cost of energy in the $2.00 per 10^6 BTU range throughout the Western Industrialized World, the current value of one horsepower over a five-year period is in excess of $600. This high energy valuation is of relatively ...
-
(Texas A&M University. Turbomachinery Laboratories, 1982)Careful attention is given to the most common, turbomachinery performance problems which result from an inadequate understanding of component and machine efficiency. Examples of several classical problems are presented and ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)With oil consumption increasing worldwide, the petroleum industry is being forced to find ever more efficient ways. Not only the exploration of inaccessible and inefficient oil fields, but also the increasing demand for ...
-
(Texas A&M University. Turbomachinery Laboratories, 1990)During the oil crisis in the 1970s, many electric utilities assigned their base load portion of electric generation requirements to nuclear and coal fired steam plants. The intermediate duty in some cases was assigned to ...
-
(Texas A&M University. Turbomachinery Laboratories, 2013)An unacceptable vibratory behavior was encountered in 2012 during the full load string test of an electric driven centrifugal compressor. The vibrations were observed on the high speed part of the shaft line and both ...
-
(Texas A&M University. Gas Turbine Laboratories, 1974)In the past, the decision to use electric motors for centrifugal compressor drives has been made only after all other possibilities to use either a steam or gas turbine have been exhausted—or so it has seemed to motor ...
-
(Texas A&M University. Turbomachinery Laboratories, 2013)Two types of prime movers are continuously applied for rotating machinery: mechanical and electric drives. This tutorial focuses on electric drives, which are actually composed of separate components: electric motor, ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)Commissioning and operating turbomachinery often create surprises especially with respect to vibration. Often not all the conditions are known under which these highly-efficient turbomachines have to operate. This case ...
-
(Texas A&M University. Turbomachinery Laboratories, 1987)Electrical damage to turbomachinery parts has caused a number of machinery failures and many hours of costly downtime. The problem of electrical voltages and currents being generated in non-electrical machines has puzzled ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)This paper presents the development process for a new variable frequency drive (VFD) system for large size compressor trains for natural gas and liquefied natural gas (LNG) applications. The paper covers the multiple steps ...
