Characteristics Of The Reciprocating Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A discussion is presented on the physical differences between centrifugal pumps and reciprocating pumps. The disparities are explained in a nonbiased manner and such knowledge should precede an introduction to reciprocating ...
Condition Monitoring Of Rolling Element Bearings Installed In Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Monitoring the condition of bearings in centrifugal pumps continues to be an important concern to pump users, especially in critical pump installations. Additionally, pump users are interested in simple, easy to use, ...
Design And Operation Of Pumps For Hot Standby Service
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Pump thermal distortion problems routinely arise in refinery applications where hot fluids must be handled. This is particularly the case when warming up standby pumps. The single stage, double suction configuration, which ...
High Head-Low Flow Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Centrifugal pumps that fall into a category defined as high head, low flow pumps are discussed. A brief history of these pump types is presented. The principle of operation and performance envelope are addressed. Comparative ...
Electric Energy Application of the New Superconductors
(Energy Systems Laboratory, 1988-09)
Electricity has been the major energy form enabling many of the significant technological breakthroughs of this century. While radical changes have occurred in how electricity is used, the underlying materials used in ...
Rotordynamic Considerations In The Design Of High Speed Centrifugal Pumps
(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. ...
Energy Recovery By Direct Contact Gas-Liquid Heat Exchange
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1988-09)
Energy from hot gas discharge streams can be
recovered by transfer directly to a coolant liquid in one of
several available gas-liquid contacting devices. The design of
the device is central to the theme of this paper, ...
Online Diagnostics Of Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Has the industrial standardization of the IBM PC/ AT as a building block for dedicated instrument computer systems brought costs down to the point where sophisticated monitoring systems are not only possible, but make good ...
Nondestructive Testing of Turbomachinery Components
(Texas A&M University. Turbomachinery Laboratories, 1988)
Nondestructive evaluation is becoming increasingly important in determining the quality of materials and fabrications used in the manufacture and maintenance of rotating machinery. NDE has long been used as a tool for ...
Optimizing Control- A Survey
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1988-09)
The major asumptions that underlay the application
of optimizing control and the properties of the methods are
presented based on the general problem of simultanuously
optimizing and controlling a plant. The separation ...
