Composite Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Design And Development Of Gas Lubricated Seals For Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Gas lubricated double seals are becoming more common in industry for pump applications where product emission, product contamination, and operating costs are a concern. Technology proven on large gas compressors is not ...
How To Avoid Building Problems Into Pumping Systems
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
A poorly performing pump frequently exhibits both hydraulic and mechanical problems. Excessive noise, vibration, degradation of discharge pressure, repeated bearing failures, and sometimes impeller breakage lead to high ...
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 ...
Thermal Test Analysis Of Bearing Frame Inline Pumps On High Temperature Service
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Testing of an API Standard 610[1] bearing frame inline pump at pumpage temperatures up to 650 degrees F is presented. The thermal response throughout the pump, and specifically in the bearing frame area, is quantified. ...
Vertical Diffuser Type Turbine, Mixed-Flow, And Axial-Flow (Propeller) Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Vertical diffuser type pumps, their application, construction, specialties and installation are discussed. Also, system curves and pump curves are handled.
Monitoring Sealless Pumps For Metal-To-Metal Contact Of The Internal Rotor
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Monitoring vibration as a predictive maintenance tool will not consistently prevent catastrophic damage and/or fluid release from sealess pumps. When vibration readings are taken periodically, a pump may be destroyed between ...
Sealless Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Magnetic drive and canned motor pumps have many common features including bearing and rotor designs, internal cooling, and lubrication. The primary differences center on the manner in which the rotating magnetic field is ...
Efficient Multiphase Pump Station For Onshore Application And Prospects For Offshore Application
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
With oil consumption increasing worldwide, the petroleum industry is being forced to find ever more efficient ways. Not only the exploration of inaccessible and inefficient oil fields, but also the increasing demand for ...
Elimination Of Cavitation-Related Instabilities And Damage In High-Energy Pump Impellers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
The suction-stage impeller of a large crude oil pipeline pump was designed by combining quasi-three dimensional flow analysis with current theories to generate an impeller geometry, which was evaluated in a half-size model ...
