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 ...
Shaft Sizing For Multistage Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
For proper sizing of pump shafts, many criteria need to be considered such as stress, deformation, and rotordynamics. The authors try to shed more light on these areas in order to ensure economic, safe, and reliable pump ...
Cavitation And Recirculation Troubleshooting Methodology
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
High reliability and large rangeability are required of pumps in existing and new plants which must be capable of reliable on-off cycling operations and especially low load duties. The reliability and rangeability target ...
Controlling Emissions To Atmosphere Through The Use Of A Dry-Sliding Secondary Containment Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Increasing concern over the emission of hazardous compounds to the atmosphere has led to stricter regulations regarding the acceptable amount of leakage from pumps. This is forcing the users and manufacturers of pumps and ...
Canned Motor And Magnetically Coupled Pumps - Applications, Operations, And Maintenance In A Chemical Plant
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The environmental requirements that drive chemical producers to move more and more to the use of the “sealless” pump are described. The development of the sealless pumps in the European industrial community and their ...
Design And Testing Of A Zero-Net Radial Taper, Radially Compliant Face Seal
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Conventional seal designs, the net radial taper changes with operating conditions so that contact is not always maintained across their entire width and leakage can occur. The “zero-net” face seal combines two ideas to ...
Enhanced Mechanical Seal Performance Through Proper Selection And Application Of Enlarged-Bore Seal Chambers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
Recent studies of enlarged-bore seal chambers document the influence of chamber design on seal performance. The studies utilize laser Doppler velocimetry (LDV), high speed videography, and computational fluid dynamics (CFD) ...
