The porch of wheel 70 produces blocking.
The quantity of the short blade 78 is multiple, and multiple short blades 78 are arranged at the wheel adjacent to the shaft 74
On disk 72, and multiple short blades 78 surround and are arranged at around the shaft 74.In the present embodiment, the short leaf
The quantity of piece 78 is three, and three short blades 78 are uniformly distributed on the wheel disc 72 along the circumference of the wheel disc 72.Often
The individual short blade 78 is arranged between two adjacent linear leafs 76, i.e. each described short blade 78 with each described in
Linear leaf 76 is arranged alternately.Each described short blade 78 is arc shaped blade, and three short blades 78 are along the wheel disc 72
Radial radiation, until extending to the edge of the wheel disc 72.Remember the original position of each short blade 78 to the linear leaf
The distance of 76 original position is T2.
Preferably, the original position of each short blade 78 with and the short blade 78 adjacent linear leaf 76
The distance between original position T2 is with the ratio of diameter D2 (impeller diameter D2) of the wheel disc 72:
T2/D2=0.219~0.4
The distance between original position and the original position of the linear leaf 76 when each short blade 78 T2 and institute
When the ratio range for stating diameter D2 (impeller diameter D2) of wheel disc 72 is 0.219~0.4, the width of the inner flow passage of the housing 34 sets
Meter is optimized, so that the more stable smoothness of the flowing of the fluid in the housing 34, while miscellaneous during fluid can be avoided
Matter produces blocking in the porch of impeller 70.
In the present embodiment, multiple linear leafs 76 are evenly spaced from one another is arranged on the wheel disc 72, multiple described
Short blade 78 is evenly spaced from one another to be arranged on the wheel disc 72, the original position of each short blade 78 and adjacent thereto is set
The distance between the original position of the linear leaf 76 put T2 is not completely equivalent.It is understood that each described short blade
The distance between 78 original position and the original position of the linear leaf 76 of setting adjacent thereto T2 can with essentially equal, with
More than 76 alternate intervals of the short blade 78 of multiple linear leafs is arranged on when on the wheel disc 72, two neighboring blade it
Between distance it is equal, so as to be more beneficial for the stabilization of flow of fluid.
Referring to Fig. 6, the end of the end of each linear leaf 76 and the short blade 78 adjacent thereto, with
And the edge of the wheel disc 72 surrounds a blade exit runner, note blade exit flow area (refers to dotted line in Fig. 6 for A2
Part);Three linear leafs 76 and three short blades 78 form six blade exit runners on the wheel disc 72, then
Six blade exit runner gross areas are impeller outlet flow area, and (figure is not for A3 to remember the impeller outlet flow area
Mark).The exit flow area A1 of the spiral case is designated as k with the ratio of the impeller outlet flow area A3.In this embodiment party
In formula, k is more than or equal to 0.2 and less than or equal to 0.5.That is, the exit flow area A1 of described spiral case and the impeller outlet runner
The ratio of area A3 is:
K=A1:A3=0.2~0.5
When the spiral case exit flow area A1 and the impeller outlet flow area A3 ratio range for 0.2~
When 0.5, the runner of enough width is reserved in the pump case 30 for the flowing of fluid, and ensureing the volume of the pump machine 100
On the premise of compact, the flowing velocity of fluid is improve, so as to improve the efficiency of the pump machine 100.
Please refer to Fig. 7, further, the linear leaf 76 is highly roughly the same with the short blade 78.Work as institute
When stating impeller 70 and being contained in the host cavity 3411, the top of the linear leaf 76 and/or the short blade 78 and the receipts
Being retained between the bottom wall of cavity volume 3411 has predetermined gap, i.e. retained between the bottom wall of the impeller 70 and the resettlement section 341
There is predetermined gap, remember that the predetermined gap is impeller clearance T3.
Note institute impeller clearance T3 is G with the ratio of diameter D2 (impeller diameter D2) of the wheel disc 72.Preferably, G is more than
Equal to 0.04 and less than or equal to 0.12.That is, described impeller clearance T3 is with the ratio of the diameter D2 of the wheel disc 72:
G=T3:D2=0.04~0.12
When the impeller clearance T3 and diameter D2 (impeller diameter D2) of the wheel disc 72 ratio range for 0.04~
When 0.12, for predetermined runner has been reserved in the flowing of fluid in the host cavity 3411, and ensureing the volume of the pump machine 100
On the premise of compact, the flowing velocity of fluid is improve, so as to improve the efficiency of the pump machine 100.
When assembling the pump machine 100 of present embodiment, first, the impeller 70 is installed in described in the drive mechanism 50
In drive shaft 54, the driving body 52 of the drive mechanism 50 is housed and the installing department of the lid 32 is fixed on
In 321.Then, the lid 32 is covered on the host cavity 3411 of the housing 34, is contained in the impeller 70
In the host cavity 3411.Finally, the pump case 30 that will have been assembled is installed in the mounting seat 10.Using this implementation
During the pump machine 100 of mode, first, make the inner chamber of the pump case 30 full of fluids such as water, fluid or gases, by it is described enter flow tube 36
It is communicated in the container for housing the fluid, and the diversion division 343 is communicated to external environment or another described for housing
In the container of fluid.Then, rotated by driving the drive mechanism 50, the impeller 70 is rotated in the spiral case.
In the presence of the pressure differential caused between the inwall of the blade and the spiral case of centrifugal force and the impeller 70, the fluid source
Source constantly from the container and it is described enter flow tube 36 enter in the spiral case, and be delivered to the external world via the diversion division 343
Change commanders or another container for housing the fluid in.
The pump machine 100 of the invention, because its impeller 70 employs the arc shaped blade structure that length is arranged alternately, makes institute
The design for stating spiral case inner flow passage is further optimized, so that the flowing of fluid is more smooth and stablizes, the conveying effect of fluid
Rate is of a relatively high.Meanwhile, the bearing of trend of the blade of the impeller 70 has complied with the rotation direction of the impeller 70, reduces stream
The wild effects such as flow separation and Secondary Flow in road, so as to improve the combination property of centrifugal pump.In addition, the pump machine 100
Monophase machine is employed as the drive mechanism for driving the impeller 70 to rotate, makes pump machine startup at lower voltages more
Easily.
Embodiment of above is merely illustrative of the technical solution of the present invention and unrestricted, although the preferably embodiment party with reference to more than
Formula has been described in detail to the present invention, it will be understood by those within the art that, can be to technical scheme
Modify or equivalent should not all depart from the spirit and scope of technical solution of the present invention.
