Design And Application Of Dual Gas Seals For Small Bore Seal Chambers
(Texas A&M University. Turbomachinery Laboratories, 1997)
Since the release of dual gas lubricated seal technology for process pumps over three years ago, this technology has provided a more versatile, efficient, safe, and less costly alternative to sealless pumps and traditional ...
Oil Lubrication Systems For Process Pumps And Related Equipment
(Texas A&M University. Turbomachinery Laboratories, 1997)
Oil lubrication systems, when required and provided for the pumping system, are the life insurance policy for the process. If the oil lubrication system should fail to perform, the results are bearing failures in pumps, ...
Experimental Evaluation Of High Energy Pump Improvements Including Effects Of Upstream Piping
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The suction-impeller (single-suction) of a 33,500hp, four-stage barrel pump used in boiler feed service at a fossil fuel steam plant experienced operating life ranging from 6.0 to 19 months. Cavitation erosion on the suction ...
Magnetic Bearings As An Impeller Force Measurement Technique
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The technique of measuring steady loads on centrifugal pump impellers via magnetic bearings is demonstrated and shown to be reliable way of clarifying loads, which have been traditionally difficult to determine both ...
Judge The Pump Hydraulic Design Through Numbers Before You Buy
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
A few well established hydraulic design parameters define the internal quality of an impeller design. Becoming familiar with those parameters and understanding their limits will enable pump buyers to make better pump buying ...
Smoke Or Substance? .. Some Misconceptions About Desirable Construction Features Of Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
What I decided to accomplish in this tutorial is to examine a few of the myths that pertain to centrifugal pump construction and to try to shed some light on their origins as well as on their validity. More specifically, ...
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 ...
Rotordynamic And Dry Running Behavior Of A Full Scale Test Boiler Feed Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Excessive rotor vibrations are one of the leading causes of damage to pump components, particularly to bearings, shaft seals, and premature wear of labyrinth surfaces. Under an EPRI contract which was awarded to Sulzer in ...
Design Of Magnetically Driven Chemical Pump To Fit ANSI B73.1 Dimensions Using A Semiopen Impeller
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
A magnetically driven sealless chemical pump was developed that employs high torque rare-earth magnets. Utilizing a semiopen impeller configuration, the pump was designed to fit into the ANSI B73.1 standard dimensional ...
