Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings.

The impeller of a kind of open water pump as shown in Figures 1 to 6, including axle positioned at center and uniformly it is laid in axle Some blades on perisporium, axle be in hollow structure, axle include in split set epimere axle 11 and hypomere axle 12, epimere axle 11 with Hypomere axle 12 is fixedly connected.Specifically, the bottom of epimere axle 11 is provided with alignment pin 111, the top of hypomere axle 12 be provided with The location hole 121 that alignment pin 111 is adapted, alignment pin 111 coordinates with the grafting of location hole 121, in order that epimere axle 11 and hypomere More preferably, the bottom of epimere axle 11 is provided with least two alignment pins 111, similarly, hypomere axle 12 to transmission effect between axle 12 Top be provided with and the one-to-one location hole 121 of alignment pin 111.

Blade is included in epimere blade 21, the edge on the side face of hypomere axle 12 axially extended on the side face of epimere axle 11 Axially extending hypomere blade 22, the bottom of epimere blade 21 is corresponding with the top of hypomere blade 22, the bottom of hypomere blade 22 Portion is on the side face of hypomere axle 12 along the direction of rotation gradually smooth curved of axle.

More than constitute agent structure of the present utility model.The work of operation principle of the present utility model and in the prior art impeller Make principle identical, therefore will not be described here.
