A floating counter-rotating vortex-eliminating device for a pump station and the pump station; the floating counter-rotating vortex-eliminating device for the pump station includes a floating driving disc, a counter-rotating gear box, a reverse-rotating disc, a plane bearing, an elastic element, and a balance weight; the floating driving disc floats on a liquid surface near a water suction end of the pump station and is driven to rotate by power generated by a vortex; the floating driving disc is connected to the reverse-rotating disc through the counter-rotating gear box, such that the reverse-rotating disc and the floating driving disc have different rotating directions; the plane bearing is mounted at a bottom of the reverse-rotating disc, and the plane bearing is connected to the balance weight through the elastic element to prevent inclination.

An annular linear induction electromagnetic pump having axial guide vanes is provided. m axial guide vanes are uniformly arranged in a flow channel of the electromagnetic pump in a circumferential direction, and a magnitude of m is equal to a number of external stators. A length of each of the guide vanes is precisely determined by a parameter P, and the value of the parameter P is calculated together by the number of the external stators, a central radius of the flow channel, a magnetic Reynolds number, a wave number of a traveling magnetic field and the mean fluid velocity. The axial guide vanes can significantly mitigate the impact on the flow field stability caused by uneven circumferential disturbances of the magnetic field and flow field, thereby achieving a flow stabilization effect with less hydraulic losses and greatly improving the flow stability in operation under off-design conditions.
