Blade, the high blade is arranged at intervals with low blades and quantity is equal；The high blade includes the connected paraxial hole section of high blade
With high blade distal shaft hole section, the high blade distal shaft hole section includes first vertical with wheel disc and parallel with wheel disc second
So that high blade distal shaft hole section section is in inverted L-shaped, described second has opening towards wheel disc direction of rotation between wheel disc
Groove profile cavity.
In this Semi-open centrifugal pump impeller with L-type blade, be arranged at intervals using high blade and low blades to be formed it is distinctive
High-low blades interlaced arrangement impeller, it is therefore prevented that prehensile crosses the phenomenon of flow medium convection current road blocking, improves fluidity；High blade
Distal shaft hole section section is inverted L-shaped and groove profile cavity of the opening towards blade direction of rotation is formed between wheel disc, parallel with wheel disc
Second partial cover plate equivalent to high blade, therefore the lift of impeller or pump can be increased, compared to equal conditions without L-shaped
The impeller or pump of blade also just improve efficiency.
Further, low blades described in the utility model are short blade.
Further, the paraxial hole section of high blade described in the utility model is integrally formed with high blade distal shaft hole section, and Gao Ye
Piece distal shaft hole section first is in smoothing junction with the paraxial hole section of high blade.
Further, blade quantity described in the utility model is more than or equal to four.
Further, the paraxial hole section of high blade described in the utility model and the curved sheet of low blades, high blade are paraxial
Hole section has identical molded line shape with low blades in same circumference radial position.
Further, axis hole described in the utility model is axially disposed keyway.
A kind of centrifugal pump, including Semi-open centrifugal pump impeller, the Semi-open centrifugal pump impeller are above-described band L-type
The Semi-open centrifugal pump impeller of blade.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in：
1st, in this Semi-open centrifugal pump impeller with L-type blade, be arranged at intervals using high blade and low blades to be formed it is peculiar
High-low blades interlaced arrangement impeller, it is therefore prevented that prehensile cross flow medium convection current road blocking phenomenon, improved fluidity；Gao Ye
Piece distal shaft hole section section is inverted L-shaped and groove profile cavity of the opening towards wheel disc direction of rotation is formed between wheel disc, is put down with wheel disc
Second capable partial cover plate equivalent to high blade, therefore the lift of impeller or pump can be increased, compared to equal conditions without L
The impeller or pump of shape blade also improve efficiency；
2nd, when low blades are shorter in length than high length of blade, prehensile is further prevented to cross the blocking of flow medium convection current road
Phenomenon, further increased fluidity.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the Semi-open centrifugal pump impeller with L-type blade of the present embodiment, including high blade 1, low leaf
Piece 2 and wheel disc 3, the center of the wheel disc 3 are provided with the axis hole 4 passed through for drive shaft, and the axis hole 4 is axially disposed keyway 5,
The high blade 1 is arranged at intervals with low blades 2 and is uniformly fixed on wheel disc 3 around the axis of axis hole 4；The high blade 1 wraps
The paraxial hole section 11 of integrally formed high blade and high blade distal shaft hole section 12 are included, the high section of blade distal shaft hole section 12 is inverted L
Shape, high blade distal shaft hole section 12 include first vertical with wheel disc 3 and parallel with wheel disc 3 second, described second and
There is groove profile cavity of the opening towards wheel disc direction of rotation between wheel disc 3.Specifically, the present embodiment central axis hole 4 can also be along axle
It is connected to the form for setting tapering and with axle interference, high blade 1 is respectively three with low blades 2, and quantity sum is six, wherein
The high paraxial hole section 11 of blade and the curved sheet of low blades 2, high 1 paraxial hole section of blade is from low blades 2 except length height is different
External same circumference radial position has identical molded line shape.
As depicted in figs. 1 and 2, in this Semi-open centrifugal pump impeller with L-type blade, using between high blade 1 and low blades 2
Distinctive high-low blades interlaced arrangement impeller is formed every setting, it is therefore prevented that prehensile crosses the phenomenon of flow medium convection current road blocking, carries
It is high to cross fluidity；The high section of blade distal shaft hole section 12 is inverted L-shaped and opening is formed between wheel disc towards wheel disc direction of rotation
Groove profile cavity, parallel with wheel disc second partial cover plate equivalent to high blade 1, there is no L-shaped blade compared to equal conditions
Impeller or pump improve efficiency, also improve lift.
As shown in figure 3, low blades 2 could be arranged to short blade, when low blades 2 are shorter in length than high 1 length of blade, enter one
Step prevents prehensile to cross the phenomenon of flow medium convection current road blocking, further increases fluidity.Using deviated splitter vane（Height leaf
Piece）When, it is significantly, to pump for the raising for crossing fluidity although the lift and flow to pump have an impact
Many special medias（Prehensile crosses flow medium）It can apply.
Tested through inventor, using the Semi-open centrifugal pump impeller with L-type blade centrifugal pump lift and efficiency
Increase（Compared to the centrifugal pump without L-shaped blade of equal conditions）, also there is good mistake when conveying prehensile and crossing flow medium
Fluidity.
