This master lid 50 is to be corresponding discoid with secondary lid 40, and inlet hole that central authorities relatively should pair lid 40 41 is outstanding is formed with a protuberance 51, and these protuberance 51 central authorities penetrate and are formed with the joining hole 52 that is the hexagonal shape;

Each flabellum 60 is to be the curved arc shape, and it has a front end, and a gradually thin rear end, and its curvature is become greatly toward tail end gradually by these flabellum 60 front ends, and gives prominence to along the edge of each flabellum 60 and to form fin 61;

These several flabellums 60 are the protuberances 51 that are surrounded on this master's lid 50, are arranged at secondary lid 40 and main the lid between 50 in the helical mode; Wherein, the fin 61 end places of each flabellum 60 utilize mode such as welding to be fixed in to lead to cover 50 surface, and are formed with the room space respectively between the opposite side portion fin 61 of each adjacent flabellum 60.

Aforementioned joining hole 52 is subjected to the motor driven rotary for being engaged to a motor (not shown) to make this impeller sets; During use, the wherein side of this impeller sets running shaft enters among the room space between each flabellum 60 for fluid, then with the motor driven rotary, by the promotion of flabellum 60 opposite side of fluid by this impeller sets running shaft thrown away and move along default pipeline, reach the purpose of drawing and carrying of fluid.

Yet the flabellum 60 in the prior art impeller sets reaching all very inconvenience in the arrangement assembling in the moulding, must spend the plenty of time, become to finish originally, and this has formed the problem that presses for improvement beyond doubt for the manufacturing speed of production of pump.

The model utility content

Technical problem underlying to be solved in the utility model is, overcomes the above-mentioned defective that prior art exists, and a kind of impeller sets of pump is provided, and it not only constructs comparatively simple, and more quick on making, convenient, and helps the production of pump.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of impeller sets of pump comprises a secondary lid, main lid and several flabellums; It is characterized in that this main lid on the surface of covering with respect to pair in the helical mode, around outstanding several flabellums that forms; Wherein, each flabellum is to be the curved arc shape, and it has a front end, and a gradually thin rear end, and its curvature becomes big by this flabellum front end gradually toward tail end; Aforesaid secondary lid is with a side relatively and be covered on main covering, and is affixed mutually with main lid, and is formed with the room space respectively between the opposite side portion wall of each adjacent flabellum.

The impeller sets of aforesaid pump, wherein pair lid central authorities penetrate and are formed with an inlet hole; The inlet hole of the described relatively secondary lid of described main lid central authorities is outstanding to be formed with a protuberance, and these protuberance central authorities penetrate and are formed with non-circular joining hole.

The impeller sets of aforesaid pump, wherein several flabellums are surrounded on the protuberance of described main lid.

The impeller sets of aforesaid pump, wherein main lid is to be corresponding discoid respectively with secondary lid.

The impeller sets of aforesaid pump, wherein secondary lid is main relatively to be covered the opposite side surface and is extruded with guide plate along described inlet hole inner edge vertical surrounding.

The impeller sets of aforesaid pump, wherein joining hole is to be the hexagonal shape.

The impeller sets of aforesaid pump, wherein main several flabellums that cover are to utilize impact style to give prominence to moulding.

Hence one can see that, and the impeller sets of pump of the present utility model need not be carried out the moulding of each flabellum seriatim and be arranged assembling, and can finish the moulding and the laying of each flabellum fast by simple processing, therefore, reduce the cost of manufacturing, effectively quickened the manufacturing speed of pump.

The beneficial effects of the utility model are that it not only constructs comparatively simple, and more quick on making, convenient, and helps the production of pump.
