EXPERIMENTAL RESEARCH INTO THE OPERATION OF A CENTRIFUGAL CANTILEVER PUMP
Keywords:
centrifugal cantilever pump; vibration; cavitation; sensors: spectrum analyzerAbstract
The paper presents experimental researches of a centrifugal cantilever pump. For the experimental studies, the following were installed on the centrifugal cantilever pump: accelerometers, a microphone, a speed sensor, pressure gauges, a vacuum gauge, and a water flow meter. The ZET 017-U2 spectrum analyzer with 2 input channels and ZETLAB software was used to collect experimental data. The paper presents the results of experimental studies of the SNR 32-160 centrifugal cantilever pump. Experimental studies of shaft angular velocity oscillations in the centrifugal cantilever pump were conducted. The root-mean-square values of the radial vibration velocity of the centrifugal cantilever pump bearings were determined, their analysis was performed, and recommendations were given. The sound pressure spectrum of the centrifugal cantilever pump was determined. The spectrum analysis revealed cavitation phenomena in the centrifugal cantilever pump, and recommendations were given for their elimination.
