Design And Testing Of Dual Seal Series Arrangements For Pressurized Barrier Fluid
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Dual mechanical seals are operated on pressurized barrier fluid systems when the pump product properties do not support reliable single seal operation. This provides added protection against environmental release of the ...
Diaphragm Development Trends For Safe Leak Free Reciprocating Process Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The application of diaphragm pumps for metering and conveying the fluids are continuously expanding because they provide zero-leakage, can run dry, have superior efficiency, offer high reliability, maximize safety and ...
Dual Gas Sealing Technology For Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Dual gas seals are gaining acceptance by industrial users as a product that offers advantages over conventional liquid lubricated seals. These advantages are measured in terms of controlling emissions, minimizing product ...
Dry Running Bellows Type Tandem Seals For VOC Services
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Dry running bellows seal technology, where the secondary (outer) seal operates in a dry condition, was originally developed in the UK and Europe for protection against primary seal failure. Over the past three years, it ...
Dynamic Loading On Pumps - Causes For Vibration
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Some insight into the mechanism which generate lateral dynamic loads, and hence vibrations, on centrifugal pumps is presented in a general way, and the individual loads are explained and quantified. Without extensive use ...
Solution To Cavitation Induced Vibration Problems In Crude Oil Pipeline Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
An output was increased on the Eat-West crude oil pipeline in Saudi Arabia, increasing shaft seal failures were encountered. These limited the operation of the pipeline. Surveys on site and detailed model tests with flow ...
Supplier Quality Improvement Process
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
The Chevron Supplier Quality Improvement Process is described herein. It starts by recalling the history of major mechanical equipment failures in the oil business. These problems led Chevron to the development of a ...
Design, Construction, And Applications Of Magnetically Coupled Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Since the early 1970s, the environmental protection has become more and more important when designing industrial plants and, today, this question is always first in any public discussion. Thus, the engineering profession ...
Evolution Of A Mechanical Seal Condition Monitoring System
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Mechanical face seals have been used in fluid handling equipment for many years, with a long history of reliability and safety. Most users of mechanical seals, however, tend to have a few critical service areas where process ...
Experimental Evaluation Of Bladder Type Pulsation Dampeners For Reciprocating Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Pulsation dampeners are frequently used to reduce piping pressure pulsations and vibrations in reciprocating pump systems. Despite their extensive use, scientific understanding of how the dampeners work and what design ...
