Benefits Of A Balanced Interference Fit Bellows Seal Design In High Temperature Corrosive Applications
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
Metal bellows seals, originally developed for the aerospace/defense industry, are now widely accepted in the petrochemical, chemical, and general industrial markets. Metal bellows seals offer enhanced dynamic tracking of ...
Zero Emission Solutions For Mechanical Seals On Light Hydrocarbons
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
While simple mechanical seals will continue to improve in performance and be extensively used, there are occasions where zero leakage is required, and where the currently recognized option is the glandless pump, which ...
Design And Operation Refinement Of A Multistage Light Hydrocarbon Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
One of the most critical pieces of equipment in an Olefin plant is the ethylene product pump. The challenge of designing a vertical process pump that will deliver a high vapor pressure liquid with poor lubricating qualities ...
Development And Qualification Of A Magnetically Coupled Process Pump For API 610 7th Edition Services
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
A magnetically coupled process pump configuration has been developed to provide strict compliance with API Standard 610, 7th Edition, and Section VIII of the ASME Code by rigorous reading and interpretation of these standards ...
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 ...
Affordable Quasi Three-Dimensional Inverse Design Method For Pump Impellers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
Traditionally, the hydraulic design of impellers has been more of an empirical art than a well-defined engineering science. Because of the empiricism, new designs have been disappointing at times. Discussed here is a “new” ...
Liquified Natural Gas Pump With Hydrostatic Journal Bearings
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
In view of the inflammability of LNG (liquefied natural gas), submerged type pumps are normally used to protect against leaks. The overhaul interval of an LNG pump, therefore, is subject to the life of its ball bearings, ...
Progressing Cavity Pumps - Proper Selection And Application
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The design and construction of progressing cavity pumps permits them to pump virtually any fluid from clean, low viscosity fluids like oil or water, to delicate products like whole cherries, to very abrasive, highly viscous ...
Design Considerations And Application Guidelines For Pumping Liquids With Entrained Gas Using Open Impeller Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The proper selection of a centrifugal pump for liquid and gas (two phase) mixtures, is highly dependent on the amount of gas and the characteristics of the mixture. The presence of entrained gases will reduce the output ...
