The invention discloses a multifunctional submersible mixed transportation vortex pump. The vortex pump comprises a suction inlet, a guide
impeller, a vortex
impeller, a pump shaft and a
discharge head, wherein the suction inlet is connected with the guide
impeller, the vortex impeller and the
discharge head in sequence into a whole; the pump shaft penetrates through the centers of the suction inlet, the guide impeller, the vortex impeller and the
discharge head. The vortex pump has the characteristics of high
corrosion resistance, freeness from collision components, low required power, high treatment
viscosity, high efficiency, prevention of emulsification effect on well fluid, multiple functions, high suitability, realization of mixed transportation of gas and liquid, fundamental
elimination of blockage,
cavitation, excessive wear, running reliability, high efficiency, low maintenance, long service life and the like, and is widely applied to
petroleum suction and conveying processes; the treatment
viscosity of viscous media is up to 300,000Pa.c, the required power is low and is not up to a half that of a pump of the same specification, blockage is prevented, the conveying percent of
solid particles is up to 75 percent, high and low-
viscosity well fluid of which the gas content is up to 68 percent can be conveyed, and all the phenomena influencing the pump performance such as blockage,
cavitation, excessive wear, damage and the like are avoided fundamentally.
