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” ...
Development And Field Test Results Of High Performance Seals For An NGL Injection Pump
(Texas A&M University. Turbomachinery Laboratories, 1997)
Improvement in the efficiency of enhanced oil recovery techniques at the Kuparak, Alaska, oil field required replacement of reciprocating pump with a larger capacity centrifugal pump. During the specification of a high ...
The Suction Performance Of Centrifugal Pumps Possibilities And Limits Of Improvements
(Texas A&M University. Turbomachinery Laboratories, 1996)
Following a brief description of the general suction performance of pumps and starting from an impeller designed for standard requirements, it will be discussed by which modifications and up to which limit the suction ...
The Control Of Variable Speed Pumps In Parallel Operation
(Texas A&M University. Turbomachinery Laboratories, 1996)
The features are discussed of a PLC based control scheme that was developed for a multipump pumping station to be used to supply oil field produced liquids (crude oil and associated water) from tanks through a dehydration ...
Two-Phase Flow Performance Of A Heat Transport Pump
(Texas A&M University. Turbomachinery Laboratories, 1997)
Heat transport pumps in Canadian deuterium uranium reactor circulate coolant to remove fuel decay heat from the reactor core during normal and accident conditions. A loss-of-coolant-accident is one condition where heat ...
The Use Of Basic Hydraulics To Solve Field Problems: Three Cases
(Texas A&M University. Turbomachinery Laboratories, 1996)
Single stage double suction horizontally split pumps are widely used in cooling tower water applications. Their operational record varies depending on installation (sump and piping detail), mode of operation, speed, specific ...
Slurry Pipeline Design For Operation With Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 1996)
The following covers what the writer sees as the main considerations involved in the design of a slurry pipeline. It is broken down into sections. This section is concerned mainly with the slurry and design of the hydraulics ...
Liquified Natural Gas Pump With Hydrostatic Journal Bearings
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
In view of the inflammability of LNG (liquefied natural gas), submerged type pumps are normally used to protect against leaks. The overhaul interval of an LNG pump, therefore, is subject to the life of its ball bearings, ...
