Description
Technical field
It the utility model is related to a kind of centrifugal pump for centrifuging impeller of pump and using the impeller.
Background technology
Water pump is the machinery for conveying liquid or being pressurized liquid, and impeller is the core component of water pump, the shape and chi of impeller
It is very little to have substantial connection with pump performance, it is the major influence factors of pump working efficiency.Impeller is solved using deviated splitter vane at present
Certainly runner blocks and improved fluidity, but deviated splitter vane due to blade height it is consistent, to have prehensile to cross flow medium also easy
There is the phenomenon blocked, it is bad to cross fluidity.
Utility model content
For deficiencies of the prior art, the purpose of this utility model be to propose a kind of centrifugation impeller of pump and
Using the centrifugal pump of the impeller, prevent prehensile to cross the phenomenon that flow medium convection current road blocks using the centrifugal pump of the impeller, carry
It is high to cross fluidity.
To achieve the above object, the technical solution adopted in the utility model is as follows：
One kind centrifugation impeller of pump, including blade and wheel disc, the center of the wheel disc are provided with the axis hole passed through for drive shaft,
The blade is uniformly fixed on wheel disc around the axis of axis hole；The blade includes linear leaf and short blade, the linear leaf
It is arranged at intervals with short blade and quantity is equal, all linear leafs is highly equal, and all short blades are highly equal, and linear leaf height
It is different to form difference in height from short blade height, make the blade on wheel disc while form length alternation sum just to interlock.
In this centrifugation impeller of pump, be arranged at intervals using linear leaf and short blade and linear leaf height with short blade height not
Same mode, there is the centrifugation impeller of pump of deviated splitter vane alternation sum high-low blades interlaced arrangement while forming peculiar, use
The centrifugal pump of the impeller prevents prehensile to cross the phenomenon of flow medium convection current road blocking, improves fluidity.
Further, linear leaf described in the utility model is highly higher than short blade height.
Further, blade quantity described in the utility model is more than or equal to four.
Further, linear leaf described in the utility model is with the curved sheet of short blade and in same circumference radial position
With identical molded line shape.
Further, axis hole described in the utility model is axially disposed keyway.
A kind of centrifugal pump, including centrifugation impeller of pump, the centrifugation impeller of pump is above-described centrifugation impeller of pump.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in：In this centrifugation impeller of pump, using coming into leaves
Piece and the mode that short blade is arranged at intervals and linear leaf height is highly different from short blade, have length leaf while forming peculiar
The centrifugation impeller of pump of piece alternation sum high-low blades interlaced arrangement, prevents prehensile to cross flow medium using the centrifugal pump of the impeller
The phenomenon blocked to runner, improved fluidity.
Brief description of the drawings
Fig. 1 is the Semi-open centrifugal pump impeller structural representation of the utility model embodiment；
Fig. 2 is the closed centrifugal impeller of pump structural representation of the utility model embodiment；
Fig. 3 is arrangement schematic diagram of the blade on wheel disc in flow passage chamber room.
In accompanying drawing, 1- linear leafs；2- short blades；3- wheel discs；4- axis holes；5- keyways；6- front shrouds.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1 to Figure 3, the centrifugation impeller of pump of the present embodiment, including linear leaf 1, short blade 2 and wheel disc 3, it is described
The center of wheel disc 3 is provided with the axis hole 4 passed through for drive shaft, and the axis hole 4 is axially disposed keyway 5；The linear leaf 1 with it is short
The quantity of blade 2 is equal, and the linear leaf 1 is arranged at intervals with short blade 2 and is uniformly fixed on wheel disc 3 around the axis of axis hole 4；
All linear leafs 1 are highly equal, and all short blades 2 are highly equal, and the height of the height of linear leaf 1 and short blade 2 is different to be formed
Difference in height, make the blade on wheel disc 3 and meanwhile formed length alternation sum height interlock.Specifically, the present embodiment central axis hole 4 can also
The form of axially disposed tapering is simultaneously connected with axle interference, and linear leaf 1 is with the curved sheet of short blade 2 and in same circumference
Radial position has identical molded line shape, and linear leaf 1 is respectively three with short blade 2, and quantity sum is six；Adopted in the present embodiment
It is arranged at intervals with linear leaf 1 and short blade 2 and the height of linear leaf 1 is higher than the mode of the height of short blade 2, forms distinctive length leaf
Piece（High-low blades）The centrifugation impeller of pump of interlaced arrangement, it is therefore prevented that prehensile crosses the phenomenon of flow medium convection current road blocking, improves
Cross fluidity.In practical application, as needed, the height of short blade 2 can also be higher than the height of linear leaf 1, be wanted as long as meeting to use
Ask.
Tested through inventor, using the impeller centrifugal pump convey prehensile cross flow medium when with good excessively stream
Property.
As shown in figure 1, the centrifugation impeller of pump can be Semi-open centrifugal pump impeller, the original position of short blade 2 according to
Conveyance capacity needs to arrange, can also be suitable with the original position of linear leaf 1.As shown in Fig. 2 the centrifugation impeller of pump can also
It is closed centrifugal impeller of pump, now centrifuging impeller of pump includes front shroud 6.
It is last it should be noted that above example is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model is described in detail with reference to preferred embodiment by pipe applicant, and one of ordinary skill in the art should manage
Solution, modifies or equivalent substitution to the technical solution of the utility model, without departing from the objective and scope of the technical program,
It all should cover among right of the present utility model.
