Characteristics Of The Reciprocating Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A discussion is presented on the physical differences between centrifugal pumps and reciprocating pumps. The disparities are explained in a nonbiased manner and such knowledge should precede an introduction to reciprocating ...
Condition Monitoring Of Rolling Element Bearings Installed In Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Monitoring the condition of bearings in centrifugal pumps continues to be an important concern to pump users, especially in critical pump installations. Additionally, pump users are interested in simple, easy to use, ...
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 ...
Design And Operation Of Pumps For Hot Standby Service
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Pump thermal distortion problems routinely arise in refinery applications where hot fluids must be handled. This is particularly the case when warming up standby pumps. The single stage, double suction configuration, which ...
High Head-Low Flow Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Centrifugal pumps that fall into a category defined as high head, low flow pumps are discussed. A brief history of these pump types is presented. The principle of operation and performance envelope are addressed. Comparative ...
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 ...
