Shimizu, Takio; Teshiba, Hironori (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 ...
-
Cornman, Robert E. (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 ...

Steiger, James E. (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 ...
-
Tucker, Robert C. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)Coatings are used to combat wear on a number of centrifugal pump components, including wear rings, vanes, diffusers, impeller seal surfaces, and bearing areas on shafts or shaft sleeves. Their use provides a manifold ...
-
Frei, Arno; Grgic, Andrej; Heil, Werner; Luzi, Armin (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 ...
-
Benvenuti, Erio; Ross, Robert T. (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 ...
-
Sabini, Eugene P.; Fraser, Warren H. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)A chart relating the efficiency of centrifugal pumps to the specific speed and capacity at the maximum efficiency capacity has been in use in the pump industry for almost forty years. While it has been useful to both the ...
-
Turpin, Jim L.; Lea, James F.; Bearden, John L. (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 ...
-
Buchanan, Edward R (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)The wear of critical pump components costs the industry millions of dollars annually. This loss can be mitigated by the use of hardfacing to minimize wear. The correct selection of a hardface coating requires an understanding ...
-
Gopalakrishnan, S. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)Pumps running in reverse as turbines are often used for energy recovery applications in the hydrocarbon processing industry. Empirical methods for predicting turbine performance from known pump performance are reviewed. ...
-
Murray, Malcolm G. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)For pumps, most attention is directed at their hydraulic, mechanical/rotating/sealing, and metallurgical aspects. Another area of concern is the structural integrity of the pump support. Key elements of this area are the ...
-
Fritsch, Thomas J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)Expert systems are a part of that developing branch of computer science known as Artificial Intelligence. Artificial Intelligence, how it related to the other branches of computer science and where expert systems fit into ...
-
Pace, Stanley E.; Florjancic, Stefan; Bolleter, Ulrich (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)At present, the majority factor limiting the designer’s ability to predict the rotordynamic behavior of multistage centrifugal pumps is the availability of accurate input data for the forces acting on the rotor. Recent ...
-
Parry, William W. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)Installations utilizing multiple reciprocating pump equipped with common suction and discharge headers can experience severe problems including cavitation, piping vibration and fatigue failure, or destruction of pump ...

Palgrave, Ronald; Cooper, Paul (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)The visual study of cavitation in pumping machinery now plays an important role in its development-particularly where high stage energies are concerned. The incomplete picture provided by traditional head decay tests is ...
