Perez, Robert X.; Knight, Claude (Texas A&M University. Turbomachinery Laboratories, 1998)The authors present two case studies where improperly applied hydraulics resulted in poor mechanical reliability, due to chronic flow instability problems. A successful hydraulic rerate of these pumps, which required minimal ...

Using Fiber-Optic Pressure Sensors To Detect Cavitation And Flow Instabilities In Centrifugal Pumps Perez, Robert X.; Lee, Chung E.; Taylor, Henry F. (Texas A&M University. Turbomachinery Laboratories, 1998)This paper introduces the benefits of applying the fiber-optic Fabry-Perot interferometer (ffpi) pressure sensor as a means of detecting cavitation and flow instabilities in centrifugal pumps. The need for monitoring dynamic ...
