In one aspect of the present invention, there is provided a multi-cylinder pumping apparatus comprising: the device comprises a vortex line cam 1, a pulley 2, a plurality of piston cylinders 3 (for example, 2 cylinders, 3 cylinders and-12 cylinders can be made), and a base 4, wherein the vortex line cam 1 can be pivotally installed on the base 4, the plurality of piston cylinders 3 are installed on the base 4 and are arranged along the circumferential direction of the vortex line cam 1, one pulley 2 is installed on a piston rod 5 of each piston cylinder 3, a vortex line slideway 6 is formed on the vortex line cam 1, and each pulley 2 is movably arranged in the vortex line slideway 6. The outer edge of the pulley 2 slides along the inner and outer edges of the vortex line slideway 6 all the time, so that the piston rod 5 reciprocates. The piston cylinder 3 is a separate component, and the design has the advantage of reducing the manufacturing difficulty and the overall cost. The vortex line slideway 6 forms a micro ball bearing structure. The vortex line slideway 6 is composed of a left-handed vortex line and a symmetrical right-handed vortex line, so that the distance between the sideline and the center of the circle changes with the change of the angle, for example, 0.5mm/18 degrees.
