RISExperimental and Numerical Investigations of Vibration Characteristics Induced by Pressure Fluctuations in a Parallel Operating Pumping System
Publisher: ASCE
Abstract: Parallel pumping systems may operate with excessive vibrations as a result of complex hydraulic excitation sources. To remove excessive vibrations, it is essential to understand the relationships between inner hydraulic ...
Experimental Investigation of Time-Frequency Characteristics of Pressure Fluctuations in a Double-Suction Centrifugal Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure fluctuation is the primary reason for unstable operations of double-suction centrifugal pumps. By using flush mounted pressure transducers in the semispiral suction chamber and the volute ...
