Stall, Stage Stall, and Surge
(Texas A&M University. Turbomachinery Laboratories, 1981)
An extensive introduction to stall, stage stall and surge is given with examples of the various stall phenomena including recirculation. Particular components including the inducer, impeller, vaneless diffuser, channel ...
Field Testing Of Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 1981)
Field testing of compressors may be carried out to monitor for performance shortfall in normal operation or to verify performance following an overhaul or revamp. Testing requires careful measurements of pressures, ...
A Practical Guide To In-Place Balancing
(Texas A&M University. Turbomachinery Laboratories, 1981)
Rotor unbalance remains one of the leading causes of deterioration and vibration of rotating machinery; but, if physical weight corrections can be made, many machines can be successfully balanced in-place with considerable ...
Flow Recirculation In Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 1981)
Recirculation in centrifugal pumps is a flow reversal at the inlet or at the discharge tips of the impeller vanes. Through analysis and tests, it is now possible to determine the flow patterns that must exist to produce ...
Online Diagnostics Of Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Has the industrial standardization of the IBM PC/ AT as a building block for dedicated instrument computer systems brought costs down to the point where sophisticated monitoring systems are not only possible, but make good ...
Nondestructive Testing of Turbomachinery Components
(Texas A&M University. Turbomachinery Laboratories, 1988)
Nondestructive evaluation is becoming increasingly important in determining the quality of materials and fabrications used in the manufacture and maintenance of rotating machinery. NDE has long been used as a tool for ...
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 ...
Startup Of A Large Compression Train - Testing Verifies Design.
(Texas A&M University. Turbomachinery Laboratories, 1985)
The startup of a reliable compressor train involves not only the design and design audit, but also startup testing to verify the functionality of the design. Startup testing usually includes mechanical and electrical system ...
The Gas Lubricated Spiral Grooved Face Seal In The Process Industry.
(Texas A&M University. Turbomachinery Laboratories, 1985)
The gas lubricated spiral grooved face seal and its application on integrally geared centrifugal compressors in the process industry is discussed. A brief description is given of the seal configuration and its operating ...
