Section blade is axial--flow blading.
Above-mentioned this blade wheel structure can only be discharged by a centrifugal impeller section, and mode is single, and this water side
Formula also causes energy loss larger.
Utility model content
Technical problem to be solved in the utility model is in view of the above-mentioned problems of the prior art, providing a kind of water outlet
The multi-stage impeller that mode is more, water pumping efficiency is high.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of multi-stage impeller, including axis and
Blade, the blade include circumferentially distributed multiple first centrifuge blades on the outer wall of axis, first centrifuge blade edge
Radially extending for axis, and between two adjacent the first centrifuge blades have gap, it is characterised in that: the blade packet
Include circumferentially distributed multiple second centrifuge blades on the outer wall of axis, second centrifuge blade along axis to extension,
And there is gap, on the flow path of fluid, second centrifuge blade position between two adjacent the second centrifuge blades
In the upstream of the first centrifuge blade.
For the loss for reducing energy, water pumping efficiency is improved, the blade further includes circumferentially distributed on the outer wall of axis
Multiple first axial blades and the second axial blade, first axial blade and the second axial blade prolong along the axial direction of axis
It stretches, first axial blade and the second axial blade are separately arranged, second centrifuge blade is arranged in first axle stream leaf
On piece, on the flow path of fluid, first centrifuge blade is located at the downstream of the first axial blade and the second axial blade
And extended by the end of first axial blade and the second axial blade, first axial blade setting second from
First runner is formed between the front of lobus cardiacus piece and the second opposite axial blade, first axial blade is far from the second centrifugation
Second flow channel is formed between the back side of blade and the second opposite axial blade.
To throw away convenient for water flow, first centrifuge blade is in axis projection radially beyond the first axial blade and the
Two axial blades are except axis projection radially.
To throw away convenient for water flow, second centrifuge blade is in axis projection radially beyond the first axial blade and the
Two axial blades are except axis projection radially.
To be uniformly discharged, second centrifuge blade is set to the middle part of the multi-stage impeller.
Compared with the prior art, the advantages of the utility model are: two centrifugal impellers that water flow is arranged by upstream and downstream
It throws away, reaches the function of increasing pressure of different location；In addition, water body is never drained the loss for also avoiding energy with runner, realize
The utilization efficiency of energy.
Detailed description of the invention
Fig. 1 is the schematic diagram of the multi-stage impeller of the utility model embodiment；
Fig. 2 is the top view of the multi-stage impeller of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Referring to Fig. 1 and Fig. 2, a kind of multi-stage impeller, including axis 1 and blade 2, blade 2 are arranged on the outer wall of axis 1.
Blade 2 includes circumferentially distributed multiple first centrifuge blades 21 on the outer wall of axis 1,22 and of the second centrifuge blade
Axial blade.Wherein, the first radially extending along axis 1 of centrifuge blade 21, and two adjacent the first centrifuge blades 21
Between have gap；Second the radially extending along axis 1 of centrifuge blade 22, and two adjacent the second centrifuge blades 22 it
Between have gap, on the flow path of fluid, the second centrifuge blade 22 is located at the upstream of the first centrifuge blade 21.Second centrifugation
Blade 22 is set to the middle part of entire multi-stage impeller.
Axial blade includes multiple first axial blades 23 and the second axial blade circumferentially distributed on the outer wall of axis 1
24, the first axial blade 23 and the second axial blade 24 are along the axially extending of axis 1, the first axial blade 23 and the second axis stream
Blade 24 separately arranges that the second centrifuge blade 22 is arranged on the first axial blade 23, on the flow path of fluid, first
Centrifuge blade 21 is located at the downstream of the first axial blade 23 and the second axial blade 24 and by the first axial blade 23 and second
The end of axial blade 24 extends, the front of the first axial blade 23 the second centrifuge blade 22 of setting and the second opposite axis
It flows and forms first runner 25, the back side and opposite second of first axial blade 23 far from the second centrifuge blade 22 between blade 24
Second flow channel 26 is formed between axial blade 24.
