The Manufacturers' World Of Coupling Potential Unbalance.
(Texas A&M University. Turbomachinery Laboratories, 1984)
Coupling balance is important to vibration free operation of turbomachinery. Understanding how and what in a coupling affects vibration is the purpose of this paper. Discussed are the basics of balancing, why a coupling ...
A Steam Turbine Efficiency Improvement Application And Conversion.
(Texas A&M University. Turbomachinery Laboratories, 1984)
This paper presents some recent technical innovations to improve mechanical drive steam turbine efficiency and presents a case study of a recent retrofit application of these features to a compressor driver. Various external ...
Variable Speed Fluid Couplings Driving Centrifugal Compressors And Other Centrifugal Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1984)
In the past, large compressors in the petrochemical industry were mostly driven in one of two ways: by steam (or gas) turbines or by constant speed electrical motors. If the flow of the compressor had to be controlled, two ...
Analysis Of Service Failures.
(Texas A&M University. Turbomachinery Laboratories, 1984)
When a component fails prematurely, it is most important that an engineering evaluation be made of the loss. If one is alert enough to learn from past problems then "Experience gained is directly proportional to equipment ...
An Improved Method To Determine The Scoring Resistance Of Turbomachinery Gearing.
(Texas A&M University. Turbomachinery Laboratories, 1984)
The petrochemical and utility industries are experiencing a growing demand for high power turbogear units for use in large gas turbine compressor and generator drives. A growing number of high speed gears with ratings up ...
An Overview Of Cogeneration Technology - Design, Operation And Maintenance.
(Texas A&M University. Turbomachinery Laboratories, 1984)
The growth of cogeneration technology started in the 1960s, but has recently accelerated with several users interested in cogeneration applications. An overview of cogeneration technology is presented, with current experience ...
Design, Control And Startup Features Of Three Parallel-Working Propane Compressors Each Having Three Stage Groups.
(Texas A&M University. Turbomachinery Laboratories, 1984)
Two main problems must be solved in the planning and execution of compressor sets to be installed within refrigeration loops. The use of several compressors with different sidestream admissions calls for the installation ...
An Empirical Solution To An Anti-Surge Control Problem.
(Texas A&M University. Turbomachinery Laboratories, 1984)
Steps taken by a du Pont team to prevent surge in a 23,000 hp process air compressor are reviewed. The process has several reactors which must interlock down quickly for safety reasons. These interlocks can occur on one, ...
Metallurgical Failure Analysis - What, Why And How.
(Texas A&M University. Turbomachinery Laboratories, 1984)
When capital expenditures arc made for plant equipment, it is routine to anticipate that this equipment will meet reliability and performance expectations and will not experience untimely failure. Being realistic, however, ...
Critical Speeds Of Turbomachinery: Computer Predictions Vs. Experimental Measurements.
(Texas A&M University. Turbomachinery Laboratories, 1984)
As a result of a continuing demand for increased performance, modern turbomachines are sometimes designed to operate near a critical speed. Machines for petrochemical and natural gas service have been purchased and delivered ...
