Dry Start Bearing For Vertical Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Compound bearings made of PTFE and synthetic rubber were developed for vertical pumps to startup without initial lubricating water. Through various experiments, they were clarified to be superior to any other bearings of ...
Table of Contents for the Proceedings of the 6th International Pump Users Symposium
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Heat Transfer In Mechanical Seals
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Numerous studies have shown that mechanical seal reliability is related to the state of the fluid between the seal faces. In turn, the fluid state depends on the seal face temperature. Unfortunately, calculating the seal ...
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 ...
