      Silvaggio, Joseph A. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The designer of the centrifugal pump impellers requires knowledge of the velocity flow field entering the impeller for several reasons. These include an assurance that a reasonably uniform field exists, that the leading ...
    • Changes In Hydraulic Component Geometries Greatly Increased Power Plant Availability And Reduced Maintenance Costs: Case Histories 
      Makay, Elemer; Barrett, James A. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      A systematic investigation was started within the Texas Utilities Generating Company Power station feedwater pump systems due to unsatisfactory unit availability, frequent equipment breakdown, high maintenance costs, and ...
    • Control Of Backflow At The Inlets Of Centrifugal Pumps And Inducers 
      Sloteman, Donald P.; Cooper, Paul; Dussord, Jules L. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      Cavitation surge or the interaction of backflow from the inlet of a centrifugal pump or inducer at low flow and low NPSH can be eliminated by the use of backflow recirculator. Experimental results from four pumps demonstrate ...
    • Does Impeller Affect NPSHR? 
      Konno, Daisuke; Yamada, Yoshiyuki (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The relationship between centrifugal pump impeller diameter, specific speed, noise and NPSH required is presented in this paper. A theoretical explanation is given to explain why NPSHR will significantly vary with impeller ...
    • Experimental Determination Of The Reverse Flow Onset In A Centrifugal Impeller 
      Barran, Jean Paul; Caignaert, Guy; Canavelis, Richard (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The importance of problems related to machines operating at partial flow rate led to Societe Hydrotechnique de France (S.H.F.) to form a working group on the subject. In order to better understand partial flow phenomena ...
    • Horizontal Process Pump Modifications To Comply With Api-610 Sixth Edition Forces And Moments 
      Steiger, James E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The forces and moments stiffness criteria established by API-610, Sixth Edition has resulted in a new generation of horizontal process pumps and baseplates, each with increased structural rigidity. Pictures and text ...
    • Improved Mechanical Seal Design Through Mathematical Modelling 
      Salant, Richard F.; Key, William E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The mechanical seal manufacturer can now offer the user new seal designs quickly and efficiently, and can respond to trouble shooting requests rapidly, through the use of modern, computerized, seal design techniques. In ...
    • Introduction To Rotordynamics Of Pumps Without Fluid Forces 
      Leader, Malcolm E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      This paper is for the user of rotating equipment, Reliability is the key to the bottom line and rotordynamics is often the significant factor in determining reliability. Rotordynamics is a very interesting and complicated ...
    • Maintenance And Troubleshooting Of Single-Stage Centrifugal Pumps 
      Nelson, W. Ed (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      A centrifugal pump’s hydraulic performance and reliability can differ drastically from its published performance expectations. The cause of the discrepancy may involve the hydraulic features of the pump. NPSH (net positive ...
    • A Map Of The Forest .. Understanding Pump Suction Behavior: Where Do We Go From Here? 
      Karassik, Igor J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
    • Predicting And Improving The Dynamic Behavior Of Multistage High Performance Pumps 
      Bolleter, Ulrich; Frei, Arno; Florjancic, Dusal (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      Good rotordynamic behavior, implying sufficient stability margin and low sensitivity to unbalance forces, is mandatory for modern high pressure multistage pumps. Stiffness, damping and mass matrices describing the forces ...
    • Pump Specifications That Improve Mechanical Seal Performance 
      Ingram, James H. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      As the chemical, petrochemical and petroleum refining industries continue to experience a slower growth rate than at any time in the last 10 years, emphasis on cost reduction, equipment reliability and “the wat we do our ...
