Face Seal Balance Ratio Selection For Two Phase Single And Multicomponent Mixtures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
It is well known that the fluid pressure distribution between the faces of a mechanical seal greatly affects seal performance. In cases where a sealed fluid changes phase from liquid to vapor as it leaks across the seal ...
The Effect Of Design Features On Centrifugal Pump Efficiency
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Charts relating the efficiency of a single stage centrifugal pump to the specific speed were presented at the Texas A&M University Third International Pump Symposium in April 1986 [1]. These charts attempted to resolve ...
The Effects Of Slurries On Centrifugal Pump Performance
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
For a centrifugal slurry pump to accurately match a pipeline system, it is necessary to know how the presence of solids will affect the pump performance. If accurate corrections are not made, it is likely that the pump and ...
Development And Experience With A New Thrust Bearing System For Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
The general use of rolling element bearings in centrifugal pumps comes as a result of their low power consumption, high stiffness and high load support capabilities. Although these bearings are popular in the light to ...
Development Of An Incipient Failure Detection Technique For Mechanical Seals
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
The technique for detecting or predicting mechanical seal failure will guarantee that plants and turbomachinery can be reliably operated and that maintenance expense can be reduced. A technique is discussed for monitoring ...
Economically Matching Circulation Water Flow To Cooling Tower Load
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Condenser cooling water flow requirements for large turbine-generator sets are controlled both by the thermal input range of the turbine and the variety of climatic conditions affecting the cooling tower. The resulting ...
Pump Vibration Analysis For The Amateur
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Maintenance is the art of prolonging or restoring the useful operating condition of a piece of equipment. Many engineers consider maintenance to be based on industrial mythology or folklore and as a result engineering ...
Pumps And Materials For Flue Gas Desulphurization Plants
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
In the commonly mostly employed, so-called, “wet technique” for the desulphurization of flue gas, stringent demands are being made on the materials of the pumps to minimize wear by corrosion and abrasion and to reach the ...
Experiences With A Numerical Method Of Calculating Slurry Pump Casing Wear
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
A numerical method computer program has been developed by the authors that enables calculation of the wear inside a slurry pumping casing. The capabilities of the program are presented along with a description of how it ...
Reducing ANSI Pump Maintenance Costs Through Component Upgrades
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Standard ANSI pumps are adequate for most services. In installations where they do not give adequate service, however; upgrades are available to improve reliability. These should be selectively applied to obtain the maximum ...
