Referring to fig. 1-3, a high efficiency low energy consumption self priming pump, including base 1, fixed mounting has device body 2 on the outer wall of base 1 one side top, install motor 3 on the outer wall of base 1 opposite side top, the output shaft end fixedly connected with pump shaft 4 of motor 3, fixed mounting has impeller 5 on the outer wall of pump shaft 4 remote from motor 3 one side, the external casing 6 of outside fixedly connected with of motor 3, fixed mounting has fixed plate 7 on the outer wall of external casing 6 bottom portion, there is rack 8 through connecting piece movable mounting on the outer wall of fixed plate 7, coaxial fixedly connected with gear 9 on the output shaft end of motor 3, and gear 9 meshes with rack 8 mutually.

The middle of the bottom end of the external shell 6 is fixedly provided with a variable frequency heating pipe 15. The heat collecting plate 14 is fixedly installed at the inner top of the external housing 6, the metal heat conducting pipe 13 is installed inside the heat collecting plate 14, and the metal heat conducting pipe 13 penetrates through the inner top of the external housing 6. The outer wall of the metal heat conducting pipe 13 far away from the heat collecting plate 14 is fixedly connected with a cavity 10, and the cavity 10 penetrates through the inner top of the external casing 6. The low boiling point solution 11 is provided in the cavity 10 on the side of the metal heat transfer pipe 13.

The chloroform solution used as the low boiling point solution 11 is a chloroform solution, and because of its low boiling point, it is easier to boil the solution and evaporate it into a gas. And the cavity 10 must be a highly sealed box to prevent heat dissipation and thereby more quickly enable the chloroform solution to reach boiling point.

The variable-frequency heating pipe 15 adopts the existing variable-frequency technology, when the heat reaches a certain temperature, the heating is stopped, and when the temperature is not high enough, the heating is automatically carried out to heat the heat to a preset temperature.
