Detailed Description

The invention will be further described with reference to the following figures and specific examples, but the scope of the invention is not limited thereto.

1. FIG. 1 is a structural diagram of a portable full tubular pump and bevel gear set, mainly comprising a filter screen 1, a trumpet tube 2, a housing 3, a motor stator 4, a motor rotor 5, a rear guide vane 6, a quick coupling 7, a bearing I8, a shaft 10 and a rotating wheel 11; the outer ring of the rotating wheel 11 is fixedly connected with the inner circle of the motor rotor 5; the rear guide vane 6 is connected with a downstream pipeline 14 through a quick joint 7. The rotating wheel 11 is fixed on the shaft 10, and a bearing I8 and a bearing II13 are respectively arranged at two ends of the shaft 10; the horn tube 1 is arranged at one end of the motor shell 3, the other end of the motor shell 3 is connected with the rear guide vane 6, and the motor stator 3 is fixed inside the motor shell 3; one end of the inner wall of the horn tube 2 is fixedly provided with a water guide cone I201, and one end of the inner wall of the rear guide vane 6 is fixedly provided with a water guide cone II 601.

The outer side of the rotating wheel 11 is directly and fixedly connected with the inner circle of the motor rotor 5, and the structure ensures that the induced impeller does not have blade top gaps, so that the generation of high-speed fluid induced cavitation at the blade top gaps is inhibited.
