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 ...
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 ...
Improvement Of A High Temperature Bellows Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
An Inconel 718 metal bellows seal has been developed to meet the demands for high temperature applications in corrosive media such as high Sulphur bearing crude oil. Finite element analysis was used to develop concepts ...
Tandem Seals For Near Zero Hydrocarbon Emissions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
More stringent regulatory limits are being placed on gaseous emissions from pumps handling hydrocarbon fluids. For example, new pumps in the Los Angeles Basin are required to have ear zero emissions. The EPA is proposing ...
Magnetic Fluid Seal System For Control Of Pump Fugitive Emissions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Pump fugitive emissions can now be controlled to near zero levels by the use of a simplified dual seal system. A magnetic fluid secondary seal traps any vapors that leak past the primary mechanical seal. This arrangement ...
