Amount, preferably meets 360/2 × flabellum quantity.
The outer diameter of the turbofan gradually increases from the front to the back since outbound course.
When the series of the turbofan be more than or equal to 3 when, the outer diameter of the turbofan since outbound course from the front to the back
The symmetric shape gradually reduced again can also gradually be increased in first.
The surface of the flabellum is usually like the prior art at paraboloid or curved surface.
The present invention solves second technical solution used by above-mentioned technical problem are as follows: a kind of multistage turbofan water pump, including
In the pump housing and the intracorporal at least one set of multistage turbofan arrangement of the pump is set, the multistage turbofan arrangement include main shaft and
At least two-stage turbofan being disposed in parallel on the main shaft, the turbofan are circumferentially positioned on the main shaft by multiple
Flabellum is constituted；The flabellum and the main shaft are axial at constant slope, are provided with water inlet, water outlet on the pump housing
And seal receptacle, the main shaft, which passes through, to be connect outside the seal receptacle stretching pump housing with power-equipment, adjacent two-stage
Spacing is provided between the turbofan, the flabellum position of turbofan described in adjacent two-stage mutually staggers.
Compared with the prior art, the advantages of the present invention are as follows: by the way that spacing is arranged between adjacent two-stage turbofan, and will
The flabellum position of adjacent two-stage turbofan mutually staggers, and fundamentally solves existing all kinds of water pumps and produces in use
Raw low efficiency, cost performance is low, the problem that active power is low, lift is inadequate, significantly improves the technical performance of existing product, makes
With performance, service life and economic benefit.

Specific embodiment
Now in conjunction with drawings and examples, present invention is further described in detail:
Embodiment one: a kind of multistage turbofan arrangement, including main shaft 3 and at least two-stage turbofan being disposed in parallel on main shaft 3
1, turbofan 1 is made of multiple flabellums 2 being circumferentially positioned on main shaft 3；Flabellum 2 and main shaft 3 are axial at constant slope, flabellum 2
Surface is plane, can also be provided with spacing 6, maximum spacing=device between adjacent two-stage turbofan 1 at paraboloid or curved surface
Turbofan series -1 in the sum of projection width of overall length-turbofans at different levels/device；The 2 position phase of flabellum of adjacent two-stage turbofan 1
Mutually it is staggered, the angle being staggered are as follows: 360/ (1.5~3) × flabellum quantity.Fig. 1 and Fig. 2 is an example of embodiment one, at this
In a example, three grade of turbofan 1 is provided on main shaft 3,2 quantity of flabellum of every level-one turbofan 1 is 4, adjacent two-stage turbofan 1
The angle that 2 position of flabellum is staggered is best angle: 360/2 × 4=45 degree.
Embodiment two: other structures are the same as example 1, the difference is that the outer diameter of turbofan at different levels 1 is from outbound course
Start gradually to increase from the front to the back.Fig. 3 and Fig. 4 is an example of embodiment two, in this illustration, the outer diameter of main shaft 3 from
Outbound course starts gradually to increase from the front to the back, wherein per 3 cross section of main shaft between adjacent two-stage turbofan 1 be it is trapezoidal, as a result,
The height of turbofan 1 successively increases backward；And there is spacing 6 between every adjacent two-stage turbofan 1.
In this embodiment, the series of turbofan 1 can be more than or equal to 3, the outer diameter of turbofan 1 since outbound course from the front to the back
Gradually increase the symmetric shape gradually reduced again in first.
