Abstract
The invention discloses a water guide cone of a submersible pump. The water guide cone of the submersible pump comprises an impeller hub, wherein one end of the impeller hub is connected with a main shaft of the submersible pump through an impeller nut, and the other end is connected with the water guide cone; the water guide cone is made of rubbers; and a cone opening part of the water guide cone is embedded and fixed with an opening of the impeller hub through an embedding structure. The rubber water guide cone is adopted, so that the effects of lightness and economy are achieved, and the water guide cone and the impeller hub can be directly connected through the embedding structure; and a traditional screw connecting mode is discarded, so that the installation is simple.
Description
Technical field
The present invention relates to submersible pump.
Background technique
When water pump normally runs, water guide cone provides uniform flow action for runner envelope.In prior art, impeller hub one end is connected with submersible pump main shaft by impeller nut, the other end is connected with water guide cone, axial-flow pump is when installing water guide cone, or to be connected with main shaft through water guide cone with a stay bolt and to fix, or four screws are set along water guide cone cone mouth portion and impeller hub is fixed, therefore trouble are installed.And existing submersible pump water guide cone all cylinder iron material, this causes die sinking costly.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of submersible pump water guide cone, reduces costs and convenient installation.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of submersible pump water guide cone, comprise impeller hub, described impeller hub one end is connected with submersible pump main shaft by impeller nut, the other end is connected with water guide cone, described water guide cone is made up of rubber, and described water guide cone cone mouth portion and impeller hub opening are fitted and fixed with by embedded structure.
Preferably, described embedded structure comprises along the bulge loop arranged in caulking groove and impeller hub opening that water guide cone cone mouth portion outer wall circumferentially arranges, and described bulge loop embeds caulking groove.
Preferably, described impeller hub opening inwall adjoins bulge loop and is circumferentially provided with groove.
The present invention adopts rubber water guide cone, and rubber water guide cone is lightly economical, and owing to adopting rubber water guide cone, water guide cone is directly connected by embedded structure with impeller hub, abandons traditional screw connecting mode, installs simple.
Therefore, the advantage that the present invention has is:
(1) rubber water guide cone coordinates closely with impeller hub.
(2) embedded connection is not connected with bolt, and structure is simple, easy for installation.
(3) quality of rubber materials is more more economical than cast iron quality, also reduces part die sinking expense simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is structural drawing of the present invention.
Embodiment
As shown in Figure 1, a kind of submersible pump water guide cone, comprises impeller hub 1, and described impeller hub 1 one end is connected with submersible pump main shaft 3 by impeller nut 4, and the other end is connected with water guide cone 2.
Wherein, described water guide cone 2 is made up of rubber, and described water guide cone cone mouth portion and impeller hub opening are fitted and fixed with by embedded structure.Concrete, described embedded structure comprises along the bulge loop 11 arranged in caulking groove 21 and impeller hub opening that water guide cone cone mouth portion outer wall circumferentially arranges, and described bulge loop embeds caulking groove and achieves being fitted and fixed with of water guide cone 2 and impeller hub 1.Quality of rubber materials is more more economical than cast iron quality, without the need to needing die sinking as cast iron water guide cone, therefore also reduces part die sinking expense.And water guide cone is directly connected by embedded structure with impeller hub, abandon traditional screw connecting mode, install simple.
In addition, described impeller hub opening inwall adjoins bulge loop and is circumferentially provided with groove 12, and the setting of this groove makes bulge loop more closely near with coordinating of caulking groove.
Claims (3)
1. a submersible pump water guide cone, comprise impeller hub, described impeller hub one end is connected with submersible pump main shaft by impeller nut, the other end is connected with water guide cone, it is characterized in that: described water guide cone is made up of rubber, described water guide cone cone mouth portion and impeller hub opening are fitted and fixed with by embedded structure.
2. a kind of submersible pump water guide cone according to claim 1, is characterized in that: described embedded structure comprises along the bulge loop arranged in caulking groove and impeller hub opening that water guide cone cone mouth portion outer wall circumferentially arranges, and described bulge loop embeds caulking groove.
3. a kind of submersible pump water guide cone according to claim 2, is characterized in that: described impeller hub opening inwall adjoins bulge loop and is circumferentially provided with groove.
