Recent Experience With Large Liquid Injected Rotary Screw Process Gas Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Advances in manufacturing techniques and design enhancements for such components as shaft seals have made it possible for liquid flooded rotary screw compressors to achieve availability, reliability, and overall performance ...
Adaptation Of A Propylene Refrigeration Compressor With Dry Gas Seals.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The retrofit of a 35000 hp, two-case centrifugal, propylene refrigeration compressor with tandem dry gas seals in DuPont's ethylene plant at Orange, Texas, is described. The installation of these dry gas seals is one of ...
Development Of A Noncontacting Seal For Gas/Liquid Applications Using Wavy Face Technology
(Texas A&M University. Turbomachinery Laboratories, 1996)
A seal has been developed and tested that incorporates a circumferential wave pattern with a sealing dam formed on a SiC face, using a proprietary process. When run against a flat carbon face, laboratory tests show that ...
Determination Of NPSHR For Reciprocating Positive Displacement Pumps - A New Approach
(Texas A&M University. Turbomachinery Laboratories, 1996)
NPSHR is a significant pump characteristic; it is often taken as a measure of minimum suction head needed to operate a pump satisfactorily. Hydraulic institute, among others, specifies a measurement of procedure for NPSHR, ...
Centrifugal Pump Vibration Caused By Supersynchronous Shaft Instability
(Texas A&M University. Turbomachinery Laboratories, 1996)
Many centrifugal pump vibration problems are due to synchronous phenomena such as vane-pass frequency energy and running speed energy. To address such problems, guidelines have been developed to assist with their identification ...
ASME B73.1m Pump Reliability Program Formation - A Data Based Approach
(Texas A&M University. Turbomachinery Laboratories, 1996)
Data are being used to determine business decisions in this day of competitive business. In years past, many business decisions have been made without the data to support them. Today, with the use of new computer programs, ...
Table of Contents for the Proceedings of the 13th International Pump Users Symposium

Inside The Sealless Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
Sealless pumps are now specified as the preferred type for handling of toxic, hazardous, and environment threatening chemicals. Magnetically driven sealless pumps have emerged as the first choice, due to their simplicity ...
Mechanical Seal Chamber Design For Improved Performance
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The influence of pump chamber design to the environment, and mechanical seal reliability has been the been the subject of a major collaborative United Kingdom study. The key mechanisms involved in controlling the flow ...
Pump Vibrations
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The reliability and failure mechanisms of high energy pumps used in the utilities industry and the high suction specific speed pumps used in the hydrocarbon processing industry show surprising parallels as to root causes. ...
