Increasing Pump Life In Abrasive Service Through State-Of-The-Art Surface Protection
(Texas A&M University. Turbomachinery Laboratories, 2000)
In hydrocarbon processing and oil and gas industries, many pumps are required to transport fluids containing some level of abrasive solids. If not properly designed and equipped with wear resisting materials, the pump ...
Improving Tribological Performance Of Mechanical Seals By Laser Surface Texturing
(Texas A&M University. Turbomachinery Laboratories, 2000)
Significant improvement in load capacity, wear resistance, friction coefficient, etc., of mechanical seals can be obtained by forming regular microsurface structure in the form of micropores on their surfaces. A feasibility ...
New Development In Centrifugal Pumps For Optimum Cavitation Performance
(Texas A&M University. Turbomachinery Laboratories, 2000)
During the past three decades, there have been notable advances in the design of pumps. In a number of projects, the designers of process plants had, during optimization of their layouts, established a requirement for pumps ...
Temperature Measurement At Low Flow On Typical ANSI Chemical Process Pumps
(Texas A&M University. Turbomachinery Laboratories, 2000)
Chemical process pumps can be required to handle highly temperature sensitive liquids. Improper operation of such a centrifugal pump can lead to potentially dangerous liquid temperatures within the pump casing. Determination ...
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 ...
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 ...
Influence Of Gas Seals On Pump Performance At Low Suction Head Conditions
(Texas A&M University. Turbomachinery Laboratories, 2000)
Pressurized gas seal technology has been applied successfully to many types of equipment, in various processes, and under diverse operating conditions. Using a readily available gas supply, typically nitrogen, the seal is ...
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 ...
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 ...
