(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. ...
How To Improve Reliability In Centrifugal Pump Systems Through The Automatic Tuneup Of Pumps Within Their Best Operational Condition
(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 ...
Guidelines For Application Of High Temperature Dual Seals
(Texas A&M University. Turbomachinery Laboratories, 2008)
High temperature services are on of the more challenging applications for mechanical seals. Herein are recommendations and guidelines for selection and application of dual metal bellows seals for use in high temperature ...
