Reciprocating Pump Valve Design
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The working mechanism and life expectancy of automatic pump check valves, which are important for the operational safety of oscillating displacement pumps, are closely examined. A calculation process for the determination ...
Rolling Bearings In Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
The primary considerations for the selection and application of rolling bearings in centrifugal pumps are discussed. These considerations apply to both the pump manufacturer and the pump user. The various types of bearings ...
Rotordynamic Considerations In The Design Of High Speed Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Operating speeds of multistage pumps tended to increase during the last decade from 4000 to 6000 rpm to 7000 to 10000 rpm, due to new super critical powerplant designs and new conversion processes in the hydrocarbon industry. ...
Practical Considerations For Pump Baseplates, Grouting And Foundations
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
For pumps, most attention is directed at their hydraulic, mechanical/rotating/sealing, and metallurgical aspects. Another area of concern is the structural integrity of the pump support. Key elements of this area are the ...
An Overview Of Hardfaced Coatings For Industrial Use
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
The wear of critical pump components costs the industry millions of dollars annually. This loss can be mitigated by the use of hardfacing to minimize wear. The correct selection of a hardface coating requires an understanding ...
Pump-Pro - A Centrifugal Pump Diagnostic Expert System
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
Expert systems are a part of that developing branch of computer science known as Artificial Intelligence. Artificial Intelligence, how it related to the other branches of computer science and where expert systems fit into ...
System Problem Experience In Multiple Reciprocating Pump Installations
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
Installations utilizing multiple reciprocating pump equipped with common suction and discharge headers can experience severe problems including cavitation, piping vibration and fatigue failure, or destruction of pump ...
Coatings For Centrifugal Pump Components
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
Coatings are used to combat wear on a number of centrifugal pump components, including wear rings, vanes, diffusers, impeller seal surfaces, and bearing areas on shafts or shaft sleeves. Their use provides a manifold ...
Power Recovery Turbines For The Process Industry
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
Pumps running in reverse as turbines are often used for energy recovery applications in the hydrocarbon processing industry. Empirical methods for predicting turbine performance from known pump performance are reviewed. ...
Reverse Indicator Cold Alignment With Graphical Plotting
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)
An update and a demonstration of the reverse indicator alignment method with graphical plotting are presented. Hot alignment methods are not covered, but it should be clear that heat rises (falls) can be plotted directly ...
