All-tubular pump with novel transmission structure

The invention discloses an all-tubular pump with a novel transmission structure, and belongs to the technical field of hydraulic engineering equipment. The all-tubular pump is formed by connecting water guide cones, a rotor, sealing assemblies, guide vanes, hubs, an impeller and bearings. According to the all-tubular pump, the impeller and the rotor form an integral structure, an external motor drives the rotor to rotate through belt transmission, then the rotor drives the impeller to rotate to do work, the sealing assemblies are arranged between the rotor and water pump pipelines at the two sides, and therefore the defects that a traditional rubber pad is large in sealing friction resistance and poor in sealing effect are overcome; the rotation of the pump impeller is not driven by an internal motor any more, damage to the walls of the pipelines is avoided, and the completeness of the overall structure of the device is improved; a flow channel can adopt a straight pipe form without being made into a bent pip
