(Texas A&M University. Turbomachinery Laboratories, 2012)
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)A poorly performing pump frequently exhibits both hydraulic and mechanical problems. Excessive noise, vibration, degradation of discharge pressure, repeated bearing failures, and sometimes impeller breakage lead to high ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)In this session, a brief introduction about electrostatic discharge phenomena will be done. Then three historical cases with Electrostatic Discharge (ESD) issue will be analyzed in order to explain how to detect Electrostatic ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)Six topics that should extend the life of a boiler feedpump will be described in detail. These topics will explore both operational and maintenance techniques that, when instituted, have been shown to extend the useful ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Many centrifugal pump reliability problems are closely related to oversizing of pumps, which leads to highly restricted discharge valve operation, and flowrates are far below the best efficiency point (BEP), which are ...
-
(Texas A&M University. Turbomachinery Laboratories, 1981)This paper covers techniques for retrofitting turbomachinery to accept "stab-in" type thermocouples for bearing temperature monitoring. The objectives of bearing temperature monitoring and shutdown systems are to (1) avoid ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)For the typical machinery engineer, the difficulties encountered with making reliability improvements lie not with the “mechanics” of improvements, but with justifying the cost of improvements. It is difficult to translate ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)This tutorial will guide the end user through the process of specifying and installing canned motor pumps in refinery services. Specific examples will be shown of both successes and failures and lessons learned will be discussed.
-
(Texas A&M University. Turbomachinery Laboratories, 2009)Subsea processing gives pump engineers permanent technical challenges due to the comprehensive specifications that often stretch the proven limits of technology. It is particularly true for pumps that have to boost a ...

(Texas A&M University. Turbomachinery Laboratories, 2012)
-
(Turbomachinery Laboratory, Texas A&M University, 2012)
-
(Turbomachinery Laboratory, Texas A&M University, 2010)New designs or modifications of existing pump facilities are required frequently in many industries due to new operating conditions, increase in product demand, pump-pipeline interaction issues, pulsation problems, net ...
-
(Texas A&M University. Turbomachinery Laboratories, 1993)In rotating machinery, torque is transmitted from shafts to coupling hubs (or vice versa) through keys, friction, or a combination of the two. As a rule; coupling hubs must be installed on shafts with a certain amount of ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)The purpose of this tutorial is to familiarize the rotating equipment engineer with in-shop hydraulic performance testing methods. The tutorial discusses the theory of similarity testing, the assumption, and inherent errors. ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
-
(Texas A&M University. Gas Turbine Laboratories, 1980)The transmission of torque from a shaft to a hub can be efficiently accomplished through the use of friction. The advantages of this system over a keyed connection are: (1) the significant reduction of stress concentrations ...
-
(Texas A&M University. Turbomachinery Laboratories, 1998)The authors present two case studies where improperly applied hydraulics resulted in poor mechanical reliability, due to chronic flow instability problems. A successful hydraulic rerate of these pumps, which required minimal ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)Herrmann Foettinger as an alternative to a regular speed changing gear for shipboard propulsion. At that time, mechanical reduction gears for such high power applications were not available. The core idea of hydrodynamic ...
-
(Texas A&M University. Turbomachinery Laboratories, 2013)An end user of a hydrogen compressor in an oil refinery application has identified existing labyrinth seals as a source of compressor inefficiency and a potential cause of rotor- dynamic instability. The objective of this ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Recently, the use of hydrogen-natural gas mixtures as a fuel, but also as a means of storing and transporting hydrogen from surplus electricity as a result of renewable energy production has drawn significant attention. ...
