Multiphase Pumps
(Texas A&M University. Turbomachinery Laboratories, 2007)
Experience With Vertical-Turbine Pumps Rebowl Upgrade
(Texas A&M University. Turbomachinery Laboratories, 2001)
Four 580 HP cooling tower feed pumps were upgraded by retrofitting improved
bowl assemblies with enclosed stainless-steel impellers.
Pumps exhibited capacity limitation up to 50% of rated and cavitation damage in
original ...
Toward Reduced Pump Operating Costs, Part Two - Avoiding Premature Failures
(Texas A&M University. Turbomachinery Laboratories, 2001)
Each year billions of dollars are spent annually on the premature or unnecessary repair and replacement of equipment. This is certainly a waste of not only our natural resources but the funds that can improve the operating ...
Development Of A Smart Pumping System
(Texas A&M University. Turbomachinery Laboratories, 2001)
In today’s global economy, process plants are under constant pressure to reduce costs. Users can no longer afford their attempts to make pumps bulletproof by upgrading component specifications. The development of a smart ...
Principles And Application Of A Diagnostic System For Mechanical Seals
(Texas A&M University. Turbomachinery Laboratories, 2001)
It is well known from long-term experience that life-cycle costs of a pump are determined by the consequential cost associated with pump failures. The failure of a pump, often originating from system-related nonpermissible ...
Tutorial On Cryogenic Submerged Electric Motor Pumps
(Texas A&M University. Turbomachinery Laboratories, 2001)
The cryogenic submerged electric motor pump described here is a unique centrifugal pump design specifically developed for handling cryogenic fluids such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid ...
Developing Sealless Integral Motor Pumps Using Axial Field, Permanent Magnet, Disk Motors
(Texas A&M University. Turbomachinery Laboratories, 2000)
Problems with mechanical shaft seals account for the majority of pump maintenance costs. When pumping critical or hazardous fluids, users can resort to sophisticated mechanical shaft sealing systems, complicated buffered ...
Corrosion Protection Design Of Seawater Pump By Boundary Element Analysis System
(Texas A&M University. Turbomachinery Laboratories, 2000)
A computer aided corrosion-analysis-system to which boundary element method (BEM) is applied has been developed, and is utilized for diagnostic galvanic corrosion and designing cathodic protection of seawater and brine ...
Toward Reduced Pump Operating Costs
(Texas A&M University. Turbomachinery Laboratories, 2000)
Pump components such as seals and couplings affect the reliability and operating costs of pumping equipment directly. By reference to basic principles, those effects will be quantified and compared with the overall running ...
Dynamic Monitoring For Early Failure Diagnosis And Modern Techniques For Design Of Positive Displacement Pumping Systems
(Texas A&M University. Turbomachinery Laboratories, 2000)
Competitive marketplace pressures for higher quality products with consistent material properties at lower cost are changing the face of chemical process manufacturing facilities. More frequently today, critical equipment ...
