Abstract
The utility model discloses a kind of water guide cone and impeller hub linkage structure, 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, an axial plane is provided with outside described water guide cone cone mouth portion, described axial plane is provided with the extension joint superimposed with impeller hub end face in the side that connects with impeller hub, is fixed between described extension joint and impeller hub end face by screw.The utility model structure is simple, easy for installation, extends pump working life.
Description
Technical field
The utility model relates to axial-flow pump.
Background technique
As shown in Figure 1, in prior art, impeller hub 1 one end is connected with submersible pump main shaft 3 by impeller nut 12, and the other end is connected with water guide cone 2, and axial-flow pump, when installing water guide cone, passes water guide cone with a stay bolt 21 and to be connected with main shaft and to fix.
In this technological scheme, it is little that small axial flow pump carries out problem, but when selecting Large Axial Flow Pump, oversize need of required stay bolt length customizes, and gives production, buying is made troubles; And water guide cone can not closely cooperate with impeller boss; On main tapping, auger shell pit affects Main Shaft Service Life.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of water guide cone and impeller hub linkage structure, facilitates the connection of water guide cone and impeller hub.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of water guide cone and impeller hub linkage structure, 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, be provided with an axial plane outside described water guide cone cone mouth portion, described axial plane is provided with the extension joint superimposed with impeller hub end face in the side that connects with impeller hub, is fixed between described extension joint and impeller hub end face by screw.
Preferably, in described water guide cone cone mouth end surface, edge is provided with the flange engaged with impeller hub opening inner circle.
Preferably, described water guide cone is provided with water-leaking hole.
Preferably, described water-leaking hole is positioned at the vertex of a cone position of water guide cone.
Preferably, described water guide cone is iron member.
The utility model uses conventional bolt water guide cone can be connected with impeller boss, and along being provided with the flange engaged with impeller hub opening inner circle in water guide cone cone mouth end surface, is convenient to location and compact siro spinning technology cooperation.
Therefore, the utility model has the following advantages:
(1) size type axial-flow pump all can use, and keeps product appearance conformity;
(2) ban and be of little use or customize bolt, give buying, produce and bring convenience;
(3) be provided with water-leaking hole, water during maintenance in impeller boss can overflow from water-leaking hole;
(4) structure is simple, easy for installation, extends pump working life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is water guide cone and impeller hub linkage structure schematic diagram in prior art;
Fig. 2 is water guide cone and impeller hub linkage structure schematic diagram in the utility model.
Embodiment
As shown in Figure 2, a kind of water guide cone and impeller hub linkage structure, comprise impeller hub 1, impeller hub is provided with blade 11, described impeller hub 1 one end is connected with submersible pump main shaft 3 by impeller nut 12, and the other end is connected with water guide cone 2, and described water guide cone is iron member.
Wherein, be provided with an axial plane 201 outside described water guide cone cone mouth portion, described axial plane is provided with the extension joint 202 superimposed with impeller hub end face in the side that connects with impeller hub, is fixed between described extension joint and impeller hub end face by screw 22.Water guide cone and impeller hub can be connected and fixed by the common screw of such employing, and structure is simple, easy for installation.
Further, in described water guide cone cone mouth end surface, edge is provided with the flange 203 engaged with impeller hub opening inner circle.Location and the compact siro spinning technology of being convenient to water guide cone and impeller hub coordinate.
And described water guide cone is provided with water-leaking hole 23.Concrete, described water-leaking hole is positioned at the vertex of a cone position of water guide cone.Water during maintenance in impeller hub can overflow from water-leaking hole, facilitates maintenance.
