Pump Rerates - When And How
(Texas A&M University. Turbomachinery Laboratories, 2001)
During the life of a plant, there often arises a need to change a pump’s rating to match a new plant operating condition or raise the mean time between repair (MTBR) of an unreliable pump. In these cases, rerating the pump ...
Best Practices In Selecting And Applying Positive Displacement Pumps
(Texas A&M University. Turbomachinery Laboratories, 2001)
Selecting a positive displacement pump is many times a confusing process. Unlike centrifugal pumps were pumping technology is familiar, positive displacement pumps operate differently than centrifugal and there is a wide ...
Pumps - 2000 And Beyond
(Texas A&M University. Turbomachinery Laboratories, 2001)
Numerical Prediction Of Cavitation In Pumps
(Texas A&M University. Turbomachinery Laboratories, 2001)
With the increase in power per unit of volume for modern pumps, driven by manufacturing costs reduction, cavitation becomes more and more the main limiting factor in pump design. The classical one-dimensional design rules ...
Centrifugal Pump Mechanical Design, Analysis, And Testing
(Texas A&M University. Turbomachinery Laboratories, 2001)
This tutorial discusses hydraulic and mechanical issues that are of primary importance in centrifugal pumps and their systems, and how pump users can best address these issues. It is shown how to concise and orderly review ...
Seal Reliability And Performance Improvements In A Large, High Pressure, High Temperature Barrel Pump
(Texas A&M University. Turbomachinery Laboratories, 2001)
Modifications to a high-pressure, high-temperature barrel pump to increase seal reliability and throughout are discussed. The pump is in unspared hydrodewaxer (HDW) feed service. The original seal design included nonpressurized ...
The Rotordynamic Integrity Of A New Machine - Vertical Hydraulic Turbine In Cryogenic Fluids
(Texas A&M University. Turbomachinery Laboratories, 2001)
This paper presents the rotordynamic characteristics of a vertical submerged hydraulic turbine generator obtained during design, manufacturing, shop testing, and site testing. The hydraulic turbine represents a new design ...
Selection Of API 614, Fourth Edition, Chapter 3, General Purpose Lube Oil System Components For Rotating Process Equipment
(Texas A&M University. Turbomachinery Laboratories, 2001)
Lube oil systems are utilized in rotating process equipment to lubricate and cool hydrodynamic bearings. These systems are essential to the life and maintenance-free operation of the process equipment. Dependable performance ...
Reducing Life-Cycle Costs For Pumps Handling Cryogenic Fluids
(Texas A&M University. Turbomachinery Laboratories, 2001)
Advancements in the science of sealing technology have had a dramatic effect in increasing equipment reliability and reducing the cost of equipment ownership. One such area of success has been the pumping cryogenic fluids ...
Improving The Reliability And Performance Of A Melt Pump Application In A Petrochemical Plant With Block Style Universal Joints
(Texas A&M University. Turbomachinery Laboratories, 2001)
A major chemical company has implemented a cost reduction and performance enhancement via universal joints on a melt pump application. The melt pump is used to push molten polyethylene through a die to produce pellets. The ...
