And What Of The Future?
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Diamond Like Carbon Coatings - Tribological Possibilities And Limitations In Applications On Sintered Silicon Carbide Bearing And Seal Faces
(Texas A&M University. Turbomachinery Laboratories, 1997)
Promising new developments to master friction and wear under fry run conditions are diamond like carbon coatings. They offer high hardness and wear resistance, combined with a low coefficient of friction. Best coating ...
A Name Well Chosen
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
A User's View Of Sealless Pumps - Their Economics, Reliability, And The Environment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Numerous surveys have shown that the shaft seal is the dominate root cause of failure for the chemical process pump. These component failures are attributed with the lion’s share of the pump maintenance cost. Moreover, ...
Root Cause Analysis Of Five Costly Centrifugal Pump Failures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Machinery failure analysis and troubleshooting are often pursued in a somewhat haphazard, unstructured fashion. This paper presents a novel, proven, and well focused approach which can quickly lead to the root cause ...
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, ...
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 ...
