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 ...
A Comparison Of The Application Of Centrifugal And Positive Displacement Pumps
(Texas A&M University. Turbomachinery Laboratories, 2000)
There are very basic differences between the centrifugal and positive displacement pump. This paper discusses some of these aspects. It is not intended to be highly theoretical, but deals with the practical differences ...
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 ...
Disc Pump-Type Pump Technology For Hard-To-Pump Applications
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper describes a unique pumping concept based on a noncontact mechanism operating solely using the principles of boundary layer and viscous drag. The first section focuses on the pumping technology itself, describing ...
Flow Margin Improvement Of Existing Cooling Water Pumps With Respect To Extreme Part Load Operation Conditions
(Texas A&M University. Turbomachinery Laboratories, 2000)
In the present paper, the adaptation of existing cooling water pumps to extreme part load condition by cutting down the impeller in the meridional plane is described. The influence of different impeller shapes on the head ...
