Analysis Of Nozzle Loads For Process Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
Under extreme conditions, pumps may be required to withstand severe nozzle loads, which often exceed the API 610 specified values. To meet these requirements, pump mechanical behavior versus nozzle loads must be examined ...
API 610 Baseplate And Nozzle Loading Criteria
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
The baseplate and nozzle loading criteria in the December 1985 draft version of API610 7th Edition is substantially different from the criteria found in the 6th Edition. The optional heavy duty baseplate criterion has been ...
Analytical And Experimental Techniques For Solving Pump Structural Resonance Problems.
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
Proper use of current analytical and experimental techniques is essential to finding and solving structural resonance problems in pumps. Available techniques vary from the relatively simple to the very complex. Accuracy ...
Design Of Pump Shaft Trains Having Variable-Speed Electric Motors
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
With converter-fed variable speed electric motors, pulsating torques inevitably occur in the air gap and can cause torsional oscillation in the whole shaft line. The origin and behavior of these torques and how to calculate ...
Development Of An Advanced Gas Turbine Driven High-Speed Centrifugal Pump For Injection Services
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
The high-speed centrifugal pump dealt with herein has been designed principally for applications in high-pressure injection for enhanced oil recovery. To assure the high output flexibility necessary for this service, the ...
Gas-Liquid Flow Through Centrifugal Pumps - Correlation Of Data
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
The head capacity characteristics of three different submersible centrifugal pumps were correlated as a function of the gas-to-liquid ratio and pressure at the pump suction. The experimental data were from two independent ...
A Powerful Application And Troubleshooting Method For Mechanical Seals
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)
Understanding the possible thermodynamic paths that a sealed fluid can follow as it goes from stuffingbox conditions, across the seal faces, and then exits to the atmosphere is a basic, but often overlooked, aspect of seal ...
Screw Pumps Of One, Two And Three Screw Design
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)
Some fluid solutions utilized throughout the world have proven to be difficult to move, using “conventional” pumps. These included gas-liquid, Newtonian and non-Newtonian fluids. The screw pump, with its inherent slow ...
Critical Speed Analysis Of An Eight-Stage Centrifugal Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)
A critical speed and unbalance response analysis of an eight-stage centrifugal pump was performed, considering the variation of stiffness and damping coefficients with speed for both the oil firm bearings and the fluid ...
Experimental Study Of The Influence Of Backflow Control On Pump Hydraulic-Mechanical Interaction
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)
A series of right-angle pump intakes, incorporating minimum axial depths and decelerating flows, has been experimentally evaluated using an air flow test procedure. Performance was measured, internal flow fields observed ...
