Deep-well pump and impeller transmission structure

According to the impeller transmission structure, the anti-wear structure is arranged in the guide vane, meanwhile, the rear-end impeller is supported, radial swing of the pump shaft is supported, the anti-wear structure is arranged in the mode that the first supporting part is close to the rear-end impeller, and in the water pumping process, the impeller shaft end of the rear-end impeller abuts against the first supporting part; and the supporting stability of the rear-end impeller in the water pumping process is ensured. The second supporting part supports the pump shaft in the radial direction, radial swing of the pump shaft is reduced, radial abrasion of the pump shaft is reduced, the rear-end impeller and the pump shaft are independently supported through the first supporting part and the second supporting part, the supporting stability of the rear-end impeller and the pump shaft is guaranteed, and meanwhile the water pumping safety of the deep-well pump working for a long time is guaranteed.
