【Abstract】 The influence of operating parameters, such as pump rotation speed, suction pressure and gas content, on the performance of a multiphase rotordynamic pump is investigated. In pumping fluid with gas, pressure boost can be improved by enhancing the pump rotation speed, thereby improving the performance of the pump to a certain degree; when the gas content is constant, by increasing the inlet pressure, the pressure boost can be enhanced and the pump efficiency be improved remarkably;when the gas content is rather high, there will be a problem of matching between the gas pressure and the fluid pressure; the performance of the multiphase pump can also be improved by means of rational design of buffer vessel and homogenizer.更多还原
