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 ...
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 ...
Selection, Design, And Field Testing Of A 10,500 HP Variable Speed Induction Motor Compressor Drive.
(Texas A&M University. Turbomachinery Laboratories, 1996)
The cooperative effort is described of equipment manufacturers,
the process plant designer and the ultimate user to specify and
design a compressor system that was driven by a 10,500 horsepower
induction motor that was ...
Planning, Preparation, And Implementation Of Turbomachinery Turnarounds.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Anyone involved in overhauling equipment during a scheduled
turnaround knows the importance of having the right people and
the right tools available in the right places at the right time.
Obviously, the orchestration ...
Turbine Overhaul Frequency Time Or Performance Based?.
(Texas A&M University. Turbomachinery Laboratories, 1996)
How long should a turbine run before it is disassembled for inspection and overhaul? This question is increasingly important in today's environment of reduced maintenance and turnaround costs. Many aspects of the degradation ...
Options For Low Speed And Operating Speed Balancing Of Rotating Equipment.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Most turbomachinery users refer to bearing vibration as one of
their major indicators of a successful repair. Frequently heard are
such comments as "we could not even tell the machine was
running." The single most ...
A Mathematical Formalism For Flexural Diaphragm Fatigue Life And Reliability Evaluation.
(Texas A&M University. Turbomachinery Laboratories, 1996)
A mathematical formalism is presented for flexural diaphragm fatigue life and reliability evaluation. The use of this formalism enables the diaphragm designer to match a customer's requirements for life and reliability, ...
A Systematic Approach To Case Recertification.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Turbomachinery life expectancy, economic conditions, and plant capacity enhancements have created a need for vintage compressors to be reevaluated and re-engineered for operational parameters that may not have been ...
Design Improvements Enhance Dry Gas Seal's Ability To Handle Reverse Pressurization.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Within the past three years, refrigeration compressors operating intermittently at subatmospheric pressures have experienced two dry gas seal failures which have been attributed, either all or in part, to reverse pressurization ...
