Two unshrouded impellers and middle double shrouded wheel are provided with slurry import, and left side open type impeller and the inlet side of right side opening type impeller
Make suitably to extend to impeller inlet respectively, make liquid ahead of time by blade effect, reduce the diffusion of runner, thus reduce import liquid
The shock loss of stream.Left side open type impeller, right side opening type impeller are reversely distributed, and left side open type impeller and right side opening type impeller close
Symmetrical in the impeller mid-plane vertical with axis.
Left side open type impeller is provided with 6 blades, and right side opening type impeller is provided with 6 blades, and middle double shrouded wheel is provided with 12 blades,
Middle double shrouded wheel (12) left side and right side are respectively arranged with 6 blades, and the left side with the blade on the right about the impeller vertical with axis
Mid-plane is symmetrical.The most uniform interlaced arrangement, the spacing distance between the most each adjacent two pieces of blades between each impeller blade
The most identical, make each impeller have identical blade passage volume, such distribution significantly reduces generation when blade rotates
Pressure pulse.Stagger arrangement distribution between left side open type impeller blade and middle double shrouded wheel blade, adjacent blades stagger arrangement angle is 30 degree,
I.e. stagger arrangement angle between left side open type impeller blade and adjacent middle double shrouded wheel blade is 30 degree；Right side opening type impeller blade
And stagger arrangement distribution between the double shrouded wheel blade of centre, adjacent blades stagger arrangement angle is also 30 degree, i.e. right side opening type impeller blade and phase
The adjacent stagger arrangement angle between middle double shrouded wheel blade is 30 degree, and such distribution advantageously reduces liquid stream and goes out the impact of stream, carries
The high guide performance of impeller, is beneficial to improve the quality of the paper produced.

Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of pulp pump impeller, it contains three impellers, respectively left side open type impeller (14),
Middle double shrouded wheel (12), right side opening type impeller (13).Between left side open type impeller (14) and middle double shrouded wheel (12)
Connected by left side centre housing (7) fixing, between right side opening type impeller (13) and middle double shrouded wheel (12), pass through right side
Centre housing (8) connects, and axis hole (11) is contained at the middle part of impeller body.
Two unshrouded impellers and middle double shrouded wheel are provided with slurry import, and left side open type impeller (14) and right side opening type impeller (13)
Inlet side make suitably to extend to impeller inlet respectively, make liquid ahead of time by blade effect, reduce the diffusion of runner, thus subtract
The shock loss of small inlet liquid stream.Left hand model impeller (14), right hand model impeller (13) are reversely distributed, and left side open type impeller
(14) symmetrical about the impeller mid-plane vertical with axis with right side opening type impeller (13).
Left side open type impeller (14) is provided with 6 blades, and right side opening type impeller (13) is provided with 6 blades, middle double shrouded wheel
