Solving The Vibration Problem Of A Vertical Multistage Cryogenic Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Recent experience in solving the shaft breakage and seal rub problem of a vertical, eight-stage liquid nitrogen pump at a plant site is documented. Several initial field tests conducted to diagnose the vibration problem ...
Complete Analysis And Simulation Of Reciprocating Pumps Including System Piping
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
A computer model is presented for the analysis and simulation of a complete reciprocating pump installation. The model takes into account cylinder thermodynamics, valve dynamics, and acoustic pulsations in the suction and ...
Vibration Monitoring Of Vertically Mounted Pumpstools For Manufacturers And Users
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Recent efforts to develop and implement techniques to monitor and diagnose problems in submerged vertical shaft pumps are summarized. Projects based on iterative analytical and experimental efforts were implemented on ...
Considerations For Proper Sizing And Material Selection To Optimize Slurry Pump Performance
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Two significant problems are commonly identified when slurry pumps are used in process industries: sizing the pump to satisfactorily suit the service conditions and selecting the appropriate wear resistant materials to ...
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 ...
