Experimental Evaluation Of Bladder Type Pulsation Dampeners For Reciprocating Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Pulsation dampeners are frequently used to reduce piping pressure pulsations and vibrations in reciprocating pump systems. Despite their extensive use, scientific understanding of how the dampeners work and what design ...
Improving Pump Reliability In Light Hydrocarbon And Condensate Service With Metal Filled Graphite Wear Parts
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
A number of single stage overhung and multistage horizontal pumps with a history of dry running seizure have been modified by replacing the metal stationary wear parts with metal filled graphite. After modification, the ...
Romex - An Expert System Testbed For Turbomachinery Diagnostics.
(Texas A&M University. Turbomachinery Laboratories, 1990)
A rule based system developed for vibration oriented diagnosis of turbomachinery for fault identification and for predictive maintenance is described. The system is implemented in a PC based PROLOG environment, with the ...
Piping Vibration Analysis.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Excessive piping vibrations are a major cause of machinery downtime, leaks, fatigue failures, high noise, fires, and explosions in refineries and petrochemical plants. Excessive vibration levels usually occur when a ...
Energy Recovery In A Gas Distribution Station By Combination Of Expanders With Planetary Gear And Optimum Single Valve Control.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The prevailing use of expansion gases in distribution stations can be economically replaced by the application of turbo expanders. The advantage of turbine impulse wheels is that they have high efficiencies, even at very ...
Online Ultrasonic Monitoring Of Bearing Wear.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Unpredicted bearing failures continue to plague industry with forced outages. As a result of these outages, many industries have attempted prevention by unnecessary inspections and premature bearing replacement. This work ...
ISO 5i99 Standard Addresses Today's Reliability Requirements For Chemical Process Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
The standards used so far by European manufacturers of chemical process pumps were only dimensional: ISO 2858, BS 24256, DIN 24256, NF E 44121. The pump manufacturer had total freedom of design provided outline dimensions ...
Gas Turbine Considerations in the Pulp and Paper Industry
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
The pulp and paper industry is one of the largest users of energy in the industrial arena. Large quantities of process steam and electrical energy are required per unit of production.
The pulp and paper industry has ...
Southern California Edison's (SCE) Research Program for Industrial Volatile Organic Compound (VOC) Emissions Control
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
SCE has developed and implemented a
research program for customer retention
through VOC emission control. Following
characterization of problematic emission
sources, SCE has identified and evaluated
a number of ...
Electrotechnologies and Industrial Pollution Control
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
The role of electrotechnologies in the control of emissions and effluents from industrial processes is discussed. Matrices are presented identifying those electrotechnologies which impact pollution in various industries. ...
