Inside The Sealless Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
Sealless pumps are now specified as the preferred type for handling of toxic, hazardous, and environment threatening chemicals. Magnetically driven sealless pumps have emerged as the first choice, due to their simplicity ...
Mechanical Seal Chamber Design For Improved Performance
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The influence of pump chamber design to the environment, and mechanical seal reliability has been the been the subject of a major collaborative United Kingdom study. The key mechanisms involved in controlling the flow ...
Pump Vibrations
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The reliability and failure mechanisms of high energy pumps used in the utilities industry and the high suction specific speed pumps used in the hydrocarbon processing industry show surprising parallels as to root causes. ...
Affordable Quasi Three-Dimensional Inverse Design Method For Pump Impellers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
Traditionally, the hydraulic design of impellers has been more of an empirical art than a well-defined engineering science. Because of the empiricism, new designs have been disappointing at times. Discussed here is a “new” ...
Pump Performance And Energy Efficiency Improvement Through Pump Refurbishment And Internal Coatings Of Horizontal Split Case Pumps
(Texas A&M University. Turbomachinery Laboratories, 2008)
Vibration Problems (Acoustical And Bearing Housing Resonance) Resolved On Centrifugal Pump
(Texas A&M University. Turbomachinery Laboratories, 2008)
Installing VFDs on pumps that were formerly constant speed pumps can cause new vibration problems to be encountered. Acoustical resonance conditions can occur in the long cross over. New methods of measuring acoustical ...
A Vibration Problem In Vertical Circulating Water Pumps
(Texas A&M University. Turbomachinery Laboratories, 2008)
Pump Baseplate Resonance Responsible For Large Piping Vibration And Component Failures
(Texas A&M University. Turbomachinery Laboratories, 2008)
Road To Reliable Pumps
(Texas A&M University. Turbomachinery Laboratories, 2007)
The purpose of this paper is to take a “back to basics” look at installation issues that affect pump reliability. Topics of hydraulic fit, baseplate installation, shaft alignment, and piping alignment will be discussed.
Numerical Simulation On A Pump Operating In A Turbine Mode
(Texas A&M University. Turbomachinery Laboratories, 2007)
This paper deals with pump as turbine (PAT) as a feasible solution to the energy problems in rural and hilly areas. PAT provides an economical alternative to actual turbines especially for pico and microhydropower generation. ...
