The invention relates to the technical field of
petroleum mechanical equipment, and particularly discloses a multi-functional mixed transportation pump. The multi-functional mixed transportation pumpis characterized in that the multi-functional mixed transportation pump includes a pump cylinder, a pump shaft, a sucking head and a discharging head, wherein the lower end of the pump cylinder is connected with the sucking head, the upper end of the pump cylinder is connected with the discharging head, a pump cylinder cavity is internally and sequentially provided with a guide wheel and an
impeller from the top to the bottom, the lower end surface of the guide wheel is attached to the lower end surface of the
impeller, shaft holes matched with the pump shaft are correspondingly formed in thesucking head, the discharging head, the
impeller and the guide wheel, the pump shaft penetrates in the pump cylinder cavity along the axial line of the pump cylinder, and penetrates through the shaftholes of the sucking head, the guide wheel, the impeller and the discharging head, the pump shaft is fixedly connected with the impeller, and moving gaps are correspondingly reserved between the shaftholes of the sucking head, the guide wheel and the discharging head and the shaft. The multi-functional mixed transportation pump has the function of multiphase flow or mixed transportation of high
viscosity liquid, liquid mediums with high
viscosity, high temperature, high
solid content or rich in gas can be better transported, phenomena of blocking,
cavitation erosion and gas locking are eliminated to maximum extent, and the multi-functional mixed transportation pump has the characteristics that operational
adaptation is high, reliability is high, the pump efficiency is high, and energy saving is achieved.
