Changes In Hydraulic Component Geometries Greatly Increased Power Plant Availability And Reduced Maintenance Costs: Case Histories
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
A systematic investigation was started within the Texas Utilities Generating Company Power station feedwater pump systems due to unsatisfactory unit availability, frequent equipment breakdown, high maintenance costs, and ...
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 ...
Table of Contents for the Proceedings of the 13th Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 1984)
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 ...
Introduction To Rotordynamics Of Pumps Without Fluid Forces
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
This paper is for the user of rotating equipment, Reliability is the key to the bottom line and rotordynamics is often the significant factor in determining reliability. Rotordynamics is a very interesting and complicated ...
Selection Strategy For Mechanical Shaft Seals In Petrochemical Plants
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
Petrochemical plants are confronted with an increasing number of available mechanical seal designs. The user must choose from among inexpensive standard seals and exotic, high engineered seal models. We have seen seal costs ...
Acoustic Resonance Phenomena In High Energy Variable Speed Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
The design of reliable pumps is of the utmost importance in petrochemical and power installations. Downtime can be costly in terms of lost production and in the power industry loss of generating capability. In order to ...
