Entrance and media outlet, the shell cover are mounted on pump case both ends, the bearing of support shaft are respectively provided in the shell cover at both ends.
Further, described left-handed oppositely oriented to the blade of impeller and dextrorotation on impeller, and the blade of same impeller
Rotation direction is identical.
Further, described left-handed to be respectively equipped with 1-40 circles to the blade of impeller and dextrorotation on impeller, it is preferable that each
Blade on impeller separately designs 2 circles.
Further, the tip of the often circle blade on the impeller is surrounded by leaf joint.
Further, the medium inlet is equipped with 2.
Further, the medium inlet is located at the both ends of pump case.
Further, the media outlet is located at the centre position of pump case.
Further, the medium is liquid or gas.
The operation principle of axis stream opposite direction turbine of the present invention is：
Due to left-handed oppositely oriented to impeller and dextrorotation to the blade of impeller, the blade rotation direction of the same impeller is identical, two leaves
Wheel is connected on same axis, when axis rotates clockwise or counterclockwise, by left-handed to impeller and dextrorotation to the fluid of impeller
Medium flow direction is always opposite；Two circle blades are respectively equipped with to impeller to impeller and dextrorotation as left-handed, close to fluid when impeller rotates
Fluid media (medium) is pushed to the second circle blade by the first lap blade at medium inlet end, and fluid media (medium) is pushed by first lap blade, stream
Speed increases, and due to the guiding of guide vane, can reduce impact of the fluid media (medium) to next circle blade；Fluid media (medium) is then by second
It encloses blade to push, fluid media (medium) flow velocity increases again, and the blade ring quantity of impeller is more, and the attainable flow velocity of fluid media (medium) is got over
Height, two impellers work together, are exactly the total flow of turbine by the fluid media (medium) addition of two impeller propelleds.When left-handed to leaf
Operation principle is also such when wheel and dextrorotation are designed as other quantity to the blade number of turns of impeller.
It is described it is left-handed be equipped with two circle blades to impeller and dextrorotation to impeller, when turbine works axis drive it is left-handed to impeller and
Dextrorotation is rotated to impeller, and fluid media (medium) is flowed into from the medium inlet at pump case both ends in pump case, the impeller first close to medium inlet
Fluid media (medium) is pushed to the second circle blade by circle blade, and fluid media (medium) passes through the promotion of first lap blade, and flow velocity increases, due to water conservancy diversion
The guiding of blade reduces impact of the fluid media (medium) to next circle blade, and fluid media (medium) is then pushed by the second circle blade, and fluid is situated between
Mass flow speed increases again, by the fluid media (medium) of two impeller propelleds collect in it is left-handed to impeller and dextrorotation to impeller among, then
From the media outlet outflow among pump case.
Compared with prior art, it advantages of the present invention and has the beneficial effect that：
1, turbine of the invention is equipped with two impellers of left and right rotation direction, the blade on the rotation direction impeller of left and right it is oppositely oriented, with
Impeller is equipped with multi-turn blade and rotation direction is identical, can not only change the flow direction of fluid media (medium), also increase the lift of turbine, improve
Working efficiency.
2, it is equipped with guide vane between the every two circles blade of turbine of the invention, can not only improves the flow velocity of medium, carries
High working efficiency, moreover it is possible to reduce impact of the fluid media (medium) to the blade on next circle impeller, reduce the abrasion of impeller.
3, impeller function of the invention obviously inhibits the whirlpool area for the generation that becomes a mandarin, and reduces flow resistance, reduce due to
The unnecessary energy loss that flow separation generates, improves the hydraulic performance of turbine, improves the working efficiency of turbine
And operation stability.
4, Design of Turbomachinery of the invention is reasonable, simple in structure, manufacturing cost is low, lift is big, flow resistance is small, operation is steady
Calmly, the advantages that work efficiency is high, highly practical, wide market.
