    • How To Avoid Building Problems Into Pumping Systems 
      Nelson, William E.; Dufour, John W. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
      A poorly performing pump frequently exhibits both hydraulic and mechanical problems. Excessive noise, vibration, degradation of discharge pressure, repeated bearing failures, and sometimes impeller breakage lead to high ...
    • Maintenance Techniques For Turbomachinery 
      Nelson, William E. (Texas A&M University. Gas Turbine Laboratories, 1979)
      This paper covers turbomachinery repair techniques that have evolved from experiences in a large gasoline refinery. Engineering design problems and upgrading of all types of compressors, drivers, and accessories are ...
    • Maintenance Techniques For Turbomachinery 
      Nelson, William E. (Texas A&M University. Gas Turbine Laboratories, 1973)
      Manufacture and maintenance of turbomachinery are completely different. The first involves shaping and assembling of various parts to required tolerances while the second involves restoration of these tolerances through a ...
    • Pump Vibrations 
      Nelson, William E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      The reliability and failure mechanisms of high energy pumps used in the utilities industry and the high suction specific speed pumps used in the hydrocarbon processing industry show surprising parallels as to root causes. ...
    • Understanding And Preventing Steam Turbine Overspeeds. 
      Nelson, William E.; Monroe, Perry C. (Texas A&M University. Turbomachinery Laboratories, 1997)
      Destructive overspeeding of steam turbines due to poor component design, inadequate maintenance, and improper operating practices are all too common. The total cost of a turbine runaway can run into the millions of dollars ...
