Description
Technical field
This utility model relates to non-varactor pump technical field, especially relates to blade pump rotor technical field.
Background technology
Centrifugal water pump uses extensively, and water pump vane is diversified with the assembling mode of pump shaft, but, impeller couples simple with pump shaft assembling, then the firmness coupled is the most not enough；Impeller couples complexity with pump shaft assembling, although the firmness of connection improves, inconvenience when impeller can be caused again to dismantle with pump shaft, even results in the damage of impeller or pump shaft.
Utility model content
The technical problems to be solved in the utility model is to provide the draw bail of a kind of impeller and pump shaft, and impeller can either be made to form coupling of secure, the advantage again with convenient disassembly with pump shaft.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of impeller and the draw bail of pump shaft, including pump shaft and impeller, described impeller includes impeller cap and impeller body, described impeller body is bonded with pump shaft, the axle head of described pump shaft is positioned at described impeller body, it is provided with along the axial dismounting tapped through hole of pump shaft on described impeller body near the position of described pump shaft axle head, described impeller cap removably connects with impeller body, and connects dismounting tapped through hole described in rear enclosed.
Described impeller body is connected axially through the first bolt at pump shaft with the axle head of pump shaft.
Described impeller cap is positioned at outside impeller body, and the outer surface of described impeller cap is streamlined, and is connected with impeller body outer surface, plays guide functions.
Described impeller cap includes hat diversion division and connecting portion, and described connecting portion is in the lower section of hat diversion division, and described connecting portion is plane with the contact surface of impeller body, and described connecting portion and impeller body are connected by the second bolt at described contact surface.
It is additionally provided with sealing ring between described impeller cap and impeller body, makes impeller cap be tightly connected with impeller body.
Use and have the beneficial effects that produced by technique scheme: this utility model employing is offered dismounting tapped through hole at impeller body and facilitated the dismounting of impeller and pump shaft, pump shaft is bonded at impeller inner sealing simultaneously, impeller can be made to couple secure with pump shaft, pump shaft does not directly contact with pumped (conveying) medium, it is to avoid pump shaft is corroded or weares and teares.
Accompanying drawing explanation
Fig. 1 is the draw bail schematic diagram of a kind of embodiment of this utility model.
Wherein, 1, impeller cap；2, the second bolt；3, impeller body；4, pump shaft；5, the first bolt；6, dismounting tapped through hole.
Detailed description of the invention
Fastness is coupled and detachability is difficult to the technical problem that gets both in order to solve the assembling of prior art impeller and pump shaft, the utility model discloses the draw bail of a kind of impeller and pump shaft, close by pump shaft in using impeller and on impeller, offer the closed technological means dismantling dismounting tapped through hole, impeller can be both made to form coupling of secure, the advantage again with convenient disassembly with pump shaft.
In order to clearly describe this utility model, with detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of impeller and the draw bail of pump shaft 4, including pump shaft 4 and impeller, impeller includes impeller cap 1 and impeller body 3, and the axle head of pump shaft 4 is positioned at impeller body 3, impeller body 3 is provided with blind end along the axial of pump shaft 4 in pump shaft 4 end, is enclosed in impeller body 3 by pump shaft 4.Impeller body 3 is bonded with pump shaft 4, and impeller body 3 is connected axially through the first bolt 5 at pump shaft 4 with the axle head of pump shaft 4.First bolt 5 passes blind end and penetrates the axle head of pump shaft 4 from the outside of impeller body 3, it is achieved fixing connection.First bolt 5 is multiple for be spacedly distributed on blind end, makes the axial force between impeller body 3 and pump shaft 4 be uniformly distributed.The wheel hub of impeller body 3 and pump shaft 4 are by bonded transmission moment of torsion, by the first bolt 5 and the transmission axial force that closely cooperates thereof.
On impeller body 3, blind end is provided with near the axle head position of pump shaft 4 along the axial dismounting tapped through hole 6 of pump shaft 4, and impeller cap 1 removably connects with impeller body 3, and connects rear enclosed dismounting tapped through hole 6.Dismounting tapped through hole 6 is positioned on the axis direction of pump shaft 4, and dismantling device can realize the relative motion of impeller and axle by this dismounting tapped through hole 6, so can dismount impeller easily.Pump shaft 4 protected by impeller cap 1, prevents pumped (conveying) medium from being contacted with pump shaft 4 by dismounting tapped through hole 6, it is to avoid pumped (conveying) medium is to the corrosion of pump shaft 4 and abrasion.Further improve, between impeller cap 1 and impeller body 3, be additionally provided with sealing ring, make impeller cap 1 be tightly connected with impeller body 3.
Impeller cap 1 is positioned at outside impeller body 3, and the outer surface of impeller cap 1 is streamlined, and is connected with impeller body 3 outer surface, plays guide functions.As preferably, impeller cap 1 shape is with impeller cover shape.
Impeller cap 1 includes hat diversion division and connecting portion, and connecting portion is in the lower section of hat diversion division, and connecting portion is plane with the contact surface of impeller body 3, and connecting portion and impeller body 3 are connected by the second bolt 2 at contact surface.General, connecting portion is annular construction member, and contact surface is ring surface, and the second bolt 2 be multiple, is uniformly distributed at equal intervals on ring surface, makes to be connected firmly between impeller cap 1 and impeller body 3 and attachment force is evenly distributed, raising connectivity robustness and reliability.
Above this utility model is described in detail; this utility model is applied specific case embodiment of the present utility model is set forth; the explanation of above example is only intended to help and understands this utility model; should be understood that; to those of ordinary skill in the art; on the premise of without departing from this utility model principle, also this utility model can be carried out some improvement, these improvement also fall in this utility model scope of the claims.
