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 ...
Design, Installation, And Test Of A Steam Injection System On An Early Frame 3 Gas Turbine In A Combined Cycle Pipeline Compressor Station.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The Frame 3 Gas Turbines have proven to be reliable drivers for pipeline compressor stations over the last 25 years. At Transco's combined cycle compressor station, a steam injection system for power augmentation was ...
Rotor Bearing And Shaft Dynamics Redesign Of A Double-Overhung Turboexpander For Reliability Improvement.
(Texas A&M University. Turbomachinery Laboratories, 1992)
A solution is presented for a lateral rotor and bearing dynamics problem on a high pressure, double-overhung turboexpander with a design operating speed of 57,300 rpm. The rotor has an expander impeller mounted at one end ...
Centrifugal Compressor Performance Enhancement Through The Use Of A Single Stage Development Rig.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Despite recent advances in computation fluid dynamics, the complex flows through centrifugal compressor components are still not totally understood. These uncertainties detract from the designer's ability to accurately ...
