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 ...
Coupling Applications for Special Purpose Machinery Multiple Flexible Membrane Types
(Texas A&M University. Turbomachinery Laboratories, 1984)
Special purpose machinery applications of flexible disc couplings with multiple convoluted diaphragms or disc packs at each end of the spacer are discussed. Couplings in this category were retrofitted on two compressor ...
Development of High Specific Speed Mixed Flow Compressors
(Texas A&M University. Turbomachinery Laboratories, 1984)
The results of a study on the aerodynamic performance of a high specific speed, mixed flow compressor are presented. The specific speed was N. = 450 to 550 (m³/min) ½ (rpm) (m⁻¾ ), with approximately a 2.0 pressure ratio ...
Torsional-Damping-Transient and Steady State
(Texas A&M University. Turbomachinery Laboratories, 1984)
Couplings play an important role in the solution of many turbomachinery torsional problems. Due to inherently high inertias, many systems have torsional natural frequencies in the units' operating range, and operational ...
Application of Single Membrance Type Flexible Power Transmission Couplings
(Texas A&M University. Turbomachinery Laboratories, 1984)
The purpose of a flexible coupling is to transmit torque from a driver to a driven machine. It is the responsibility of the application engineer to assure that the coupling selected will transmit this torque with a minimum ...
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 ...
