Axial-flow pump

The invention belongs to the technical field of axial-flow pumps, and discloses an axial-flow pump. The axial-flow pump comprises a shell body assembly provided with a water inlet port and a water outlet port, a stator assembly arranged in the shell body assembly, and a rotor assembly comprising a cylindrical rotor body and blades, wherein the rotor body is arranged in the stator assembly, the two ends of the rotor body are rotationally connected with the shell body assembly, the plurality of blades are annularly arranged on the inner wall of the rotor body, and the rotor assembly can rotate relative to the stator assembly after being powered on, so that the blades drive liquid to be conveyed from the water inlet port to the water outlet port. The two ends of the rotor body are rotationally connected with the shell body assembly, so that the rotor body cannot axially move in the shell body assembly and the stator assembly, the matching accuracy of the stator assembly and the rotor assembly can be improved, th
