| Abstract: | When untis with screw pumps transport crude oil from tank barge, Whichvery often pro-duces vibration and noise. In this paper, by analysis of energy equation sucking-produces, computation methods of critical rotative velocity of cavitation was deduced, the theoretical criterion for preventing the cavity phenomenon and determining fine running rotative velocity of pumps was provided from the computation formula. |
