Mixer Mechanical Design - Fluid Forces
(Texas A&M University. Turbomachinery Laboratories, 2002)
This paper describes the mechanical design of a mixer with the emphasis on the fluid forces that are imposed on the impellers by the fluid continuum in the mixing vessel. The analysis shows that the forces are a result of ...
Short Courses / International Pump User Symposium (19th : 2002)
(Texas A&M University. Turbomachinery Laboratories, 2002)
Avoiding Failures In Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 2002)
Pump reliability problems are responsible for a large amount of the maintenance budget and lost-opportunity cost at chemical plants, refineries, and many electric utilities. This tutorial outlines the typical reasons for ...
Prefilled Equipment Baseplates - How To Get A Superior Equipment Installation For Less Money
(Texas A&M University. Turbomachinery Laboratories, 2002)
This paper outlines a new void-free baseplate installation method that saves over 30 percent of the installation costs, when compared to traditional two-pour grouting methods. Common field installation problems are discussed, ...
Optimizing Pumping Systems To Minimize First Or Life-Cycle Cost
(Texas A&M University. Turbomachinery Laboratories, 2002)
Numerical optimization methods offer a powerful new technology for pump users when combined with pumping system analysis software. Whether the design goal is to reduce first costs or life-cycle costs, this technology ...
Operation And Current Developments Of Self-Contained, Self-Lubricating Thrust And Journal Bearings Systems
(Texas A&M University. Turbomachinery Laboratories, 2002)
Self-lubricating, self-contained fluid-film thrust and journal bearings have been in use since the 1920s. These bearing systems offer relative simplicity in a reliable, stand-alone package. Recent testing has shown that ...
API 610 Ninth Edition Highlights
(Texas A&M University. Turbomachinery Laboratories, 2002)
API Standard 610, “Centrifugal Pumps for Petroleum, Heavy Duty Chemical and Gas Industry Services,” has been revised from the Eighth Edition to the Ninth Edition and developed into an International Standard, ISO 13709. The ...
Upthrust Problems On Multistage Vertical Turbine Pumps
(Texas A&M University. Turbomachinery Laboratories, 2005)
Vertical turbine pumps are designed to operate with the pump shafts in tension (downthrust). Most pump and motor manufacturers caution users to not operate the vertical turbine pumps at conditions that result in “upthrust.” ...
Active Lift Seal Technology Impacted On Water Injection Services
(Texas A&M University. Turbomachinery Laboratories, 2005)
Increasing environmental awareness and the ongoing need for improved reliability has seen an increase in the number of water reinjection installations, both onshore and offshore, and in particular in recent years, the use ...
