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 ...
Compressor Field Performance Evaluation Techniques
(Texas A&M University. Turbomachinery Laboratories, 1981)
During the course of this presentation on field performance evaluation techniques, a variety of turbomachinery field performance situations will be explored. For these tests, suggested ideas and guidelines for their ...
Electromagnetic Shaft Current Control
(Texas A&M University. Turbomachinery Laboratories, 1981)
Four Compressor Trains Of A Large Ethylene Plant-Design, Audit, Testing And Commissioning
(Texas A&M University. Turbomachinery Laboratories, 1981)
Each new project that a company initiates should allow the mechanical developments up to that time to be applied at the proper point when the design premise is established. This paper will review what is considered a ...
Field Experience And Solution Of A Fractional Frequency Vibration Problem On A High Speed Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 1981)
This paper describes how a serious field vibration problem on a high speed centrifugal compressor using tilting pad bearings was identified, following the introduction in the plant of simple methods of vibration recording ...
