Tutorial On Special Purpose Pumps-Pitot; Progressing Cavity; Air Operated Diaphragm; And Hydraulically Actuated Diaphragm
(Texas A&M University. Turbomachinery Laboratories, 1997)
Double Gas Seal With Coplanar Coaxial Rayleigh Pad Faces For Pump Sealing Applications
(Texas A&M University. Turbomachinery Laboratories, 1999)
There has been a rapid growth in the application of noncontacting double seals with a gas buffer fluid to pump sealing. The advantages of such a sealing arrangement are:
• There is no liquid buffer fluid to maintain or ...
Finding And Eliminating Chronic Pump Failures
(Texas A&M University. Turbomachinery Laboratories, 1999)
A Gulf Coast refinery decided to actively address rising pump maintenance costs and risk of production losses by using accumulated failure data and maintenance costs to identify bad actor pumps, then solving the problems ...
Development Of A Twin Hybrid Noncontacting Gas Seal And Its Application To Process Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
In this paper, an innovative approach of applying gas-lubricated, noncontacting sealing technology to process pumps is presented, in which a novel “twin hybrid” design is incorporated to address the issues of gas seal ...
Component Balance For Centrifugal Pumps - Effects Of Product Design, Balance Machine Tooling, And The Balancing Process On Balancing Repeatability
(Texas A&M University. Turbomachinery Laboratories, 1999)
Balancing of pump rotating components, especially impellers, is common practice. The purpose of this effort was to determine the proper design of pump components and balance arbors, create appropriate procedures, and ...
Magnetic Fluid Seal System For Control Of Pump Fugitive Emissions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Pump fugitive emissions can now be controlled to near zero levels by the use of a simplified dual seal system. A magnetic fluid secondary seal traps any vapors that leak past the primary mechanical seal. This arrangement ...
Shaft Sizing For Multistage Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
For proper sizing of pump shafts, many criteria need to be considered such as stress, deformation, and rotordynamics. The authors try to shed more light on these areas in order to ensure economic, safe, and reliable pump ...
Finite Element Transient Thermal Analysis Of An Axially Split Horizontal Multistage Pump
(Texas A&M University. Turbomachinery Laboratories, 1999)
Often the industrial power generation market specifies that boiler feedpumps must be capable of withstanding thermal transient conditions when operating in boiler feed service. A thermal transient analysis was performed ...
Material Problems And Solutions - A Metallurgical Perspective
(Texas A&M University. Turbomachinery Laboratories, 1996)
Pumps are an essential component of most industrial processes. Reliability is a major concern of pump manufacturers and users, since unexpected shutdowns can have serious and costly implications, including loss of production. ...
A Case Study: Unusual Problems Discovered During The Rerate Of 2800 HP Boiler Feed Water Pumps And Turbines
(Texas A&M University. Turbomachinery Laboratories, 1996)
The boiler feedwater system in a world scale ethylene plant utilized horizontal multistage barrel case pumps and single stage impulse type steam turbine drivers with mechanical governors. As part of a major debottlenecking ...
