    • Karassik, Igor J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
    • Jackson, Charles (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Hot and cold alignment techniques are addressed, with graphical plotting of reverse dial indicator alignment maps. An alignment program with a two sets of data for cross checking and suggested proper tooling and procedures ...
    • Buse, Frederic; Stoughton, C. Dean (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      A magnetically driven sealless chemical pump was developed that employs high torque rare-earth magnets. Utilizing a semiopen impeller configuration, the pump was designed to fit into the ANSI B73.1 standard dimensional ...
    • Schommer, Harry; Johnson, Thomas G. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Since the early 1970s, the environmental protection has become more and more important when designing industrial plants and, today, this question is always first in any public discussion. Thus, the engineering profession ...
    • Olmos, Frank (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Mechanical face seals have been used in fluid handling equipment for many years, with a long history of reliability and safety. Most users of mechanical seals, however, tend to have a few critical service areas where process ...
    • Singh, Pawam J.; Chaplis, William K. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Pulsation dampeners are frequently used to reduce piping pressure pulsations and vibrations in reciprocating pump systems. Despite their extensive use, scientific understanding of how the dampeners work and what design ...
    • Kamin, Robert P (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      A number of single stage overhung and multistage horizontal pumps with a history of dry running seizure have been modified by replacing the metal stationary wear parts with metal filled graphite. After modification, the ...
    • Fabeck, Pierre; Erickson, R. Barry (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      The standards used so far by European manufacturers of chemical process pumps were only dimensional: ISO 2858, BS 24256, DIN 24256, NF E 44121. The pump manufacturer had total freedom of design provided outline dimensions ...
    • Mayes, Jared D. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Centrifugal pump design plays an essential role in the safe operation of any refinery or chemical processing plant. In analyzing the performance of centrifugal pumps, pump operating time to failure is almost always limited ...
    • Heatley, Jeremy M.; Giffrow, Matthew (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Over the years, close attention has been paid in process facilities to the pumping of light hydrocarbons. Leakage of these products can and do cause environmental and health threatening situations. Since attention has been ...
    • Bowman, Dennis G.; Marscher, William D.; Reid, Stephen R. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Delmarva Power Indian River Power Station’s Unit 4 has had boiler feed pump reliability problems since startup in 1980. The pump has been rebuilt nine times with post overhaul operability ranging from 30 minutes to 16 ...
    • Bloch, Heinz P (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Machinery failure analysis and troubleshooting are often pursued in a somewhat haphazard, unstructured fashion. This paper presents a novel, proven, and well focused approach which can quickly lead to the root cause ...
    • Frei, Arno; Gulich, Johann; Eichhorn, Guenther; Eberl, Josef; McCloskey, Thomas H. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Excessive rotor vibrations are one of the leading causes of damage to pump components, particularly to bearings, shaft seals, and premature wear of labyrinth surfaces. Under an EPRI contract which was awarded to Sulzer in ...
    • International Pump Users Symposium (7th : 1990) (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
    • Eierman, Ronald G. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
      Numerous surveys have shown that the shaft seal is the dominate root cause of failure for the chemical process pump. These component failures are attributed with the lion’s share of the pump maintenance cost. Moreover, ...
