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 ...
Regenerative Boiler Feedwater Heater Economics
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
The basic Rankine Vapor Cycle has been
repeatedly modified to improve efficiency.
Always, the objective is to produce more power
from constant fuel, or constant power from less
fuel. Pressures and temperatures have ...
Evaporative Roof Cooling- A Simple Solution to Cut Cooling Costs
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
Since the “Energy Crisis” Evaporative Roof Cooling Systems have gained increased acceptance as a cost effective method to reduce the high cost of air conditioning. Documented case histories in retro-fit installations show ...
Microcomputer Analysis of Pumping System Performance
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
With today’s emphasis on efficient use and conservation of energy, selecting the correct pump for a given application requires not only a concise performance evaluation but also detailed economic analysis. A microcomputer ...
Process Integration of Industrial Heat Pumps
(Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
The integration of heat pumps into industrial
processes shows potential for energy savings. Heat
pumps must, however, be integrated properly relative
to the process pinch and the unit operations in the
process. The ...
