Discussion Groups / International Pump User Symposium (19th : 2002)
(Texas A&M University. Turbomachinery Laboratories, 2002)
Solving Structural Vibration Problems Using Operating Deflection Shape (ODS) And FEA: Part I & Part II
(Texas A&M University. Turbomachinery Laboratories, 2009)
This tutorial focuses on vibration issues in pumps primarily for power plants, refineries, and municipal water and waste water treatment plants. Over the years, the original equipment manufacturer (OEM) and the end user ...
Successful Modification Of Vertical-Turbine Pumps For Capacity And Reliability Improvement
(Texas A&M University. Turbomachinery Laboratories, 2000)
A modification of seven 560 hp vertical-turbine pumps was carried out with outstanding
results to improve their actual capacity. The installation was limited to 64% of its rated
capacity, which was never reached, and the ...
Mechanical Seals In Dead-End Service In The Pulp And Paper Industry
(Texas A&M University. Turbomachinery Laboratories, 2000)
The pulp and paper industry as well as all other industry branches are subject to continuous, ongoing development. Mechanical seals have already replaced stuffing-box packings in virtually all pulp and paper factories in ...
Multiphase Pumping With Twin-Screw Pumps - Understand And Model Hydrodynamics And Hydroabrasive Wear
(Texas A&M University. Turbomachinery Laboratories, 2000)
Crude oil and gas production can be enhanced by multiphase pumping from the well subsea to far distant production platforms. The twin-screw pump has proven quite suitable for this application. The positive displacement ...
Investigations Into The Contamination Of Lubricating Oil In Rolling Element Pump Bearing Assemblies
(Texas A&M University. Turbomachinery Laboratories, 2000)
The use of rolling element bearings in pumps is standard practice. Of the many factors that affect their long-term performance, contamination in the bearing lubricating oil plays a major part. Of particular concern are ...
Tutorial On Steam Turbine Drivers For Fossil And Nuclear Feed Pump Applications
(Texas A&M University. Turbomachinery Laboratories, 2008)
This tutorial will present an overview of the operation and design of steam turbines used for driving reactor and boiler feed pumps, called a boiler feed pump turbine (BFPT). Overall, these turbines are designed in much ...
Positive Displacement Reciprocating Pump Fundamentals - Power And Direct Acting Types
(Texas A&M University. Turbomachinery Laboratories, 2008)
This tutorial is intended to provide an understanding of the fundamental principles of positive displacement reciprocating pumps of both power and direct active types. Topics include: 1. A definition and overview of the ...
Evaluation Of Rotordynamic Criteria For Multistage Pump Shafts
(Texas A&M University. Turbomachinery Laboratories, 2008)
For the last 20 to 30 years rotordynamic tools with ever increasing simulation capabilities have been available for the design of multistage centrifugal pumps. Nevertheless, customers sometimes still specify criteria ...
Adjustable Speed Drives Applied To Large Ac Induction Motor And Pump Systems
(Texas A&M University. Turbomachinery Laboratories, 2008)
Adjustable speed drives (ASDs) are commonly used today in conjunction with large alternating current (AC) induction motors to drive pumps. The ASD application can provide many operational and energy conservation advantages. ...
