Description
Technical field
The utility model relates to a kind of impeller.
Background technique
The flabellum smooth curved of the impeller in existing water turbine and steam turbine, contact with flowing medium and produce reaction force, promote wheel rotation and produce power, the efficiency playing the impeller of guiding drainage is very important, be directly connected to the conversion ratio of energy, present impeller blade smooth surface, can not make full use of the kinetic energy of fluid.
Model utility content
The purpose of this utility model is to provide a kind of impeller improving fluid dynamic energy utilization ratio.
For solving the problem, technical solution adopted in the utility model is:
A kind of impeller, comprise the wheel hub be fixedly connected with wheel shaft, the leaf be fixedly installed on wheel hub outer side wall fan and be arranged on leaf fan surface guide groove, described leaf fan is provided with guide groove with fluid stress surface of contact, described guide groove is arc, the described guide groove of arc is more than one, and described leaf fan is more than three.
Furtherly, described guide groove is genesis analysis on leaf fan, and the direction spacing that the spacing between described guide groove is left away with fluid increases gradually.
Furtherly, described leaf fan is provided with three guide grooves, the spacing between the adjacent channels of three described guide grooves increases gradually with the distance of leaf fan away from wheel hub.
Furtherly, described guide groove cross section is arc.
Furtherly, described guide groove cross section is parabolic arch, and the parabola summit of described parabolic arch is positioned at the side away from wheel hub bottom guide groove.
The beneficial effect adopting technique scheme to produce is: the utility model arranges guiding gutter, the active force that increase fluid and leaf are fanned on leaf fan surface, increases the guiding of fluid, thus increases the conversion of fluid dynamic energy, improve the utilization ratio of the energy.
Guide groove increases gradually in the spacing of leaf fan direction of extension arrangement, can reduce leaf like this and fan outermost stress and deformation, increases leaf fan operating reliability.
Setting the increasing away from the distance of direction apart from wheel hub with fluid of guide groove, the wake flow after avoiding the excessive water conservancy diversion of convection cell to cause water conservancy diversion forms eddy current, and it is unfavorable to cause vane rotary on the contrary.
The cross section of guide groove can be camber line and straight line surround arc, lower arcuate surface is avoided producing flow-disturbing with fluid contact, reduces the negative effect that guide groove causes current further.
The cross section of guide groove can also be the parabolic arch that parabola and straight line surround, and parabola summit is positioned at the side away from wheel hub bottom guide groove, when not forming too much eddy current, flow-disturbing, the conversion of energy can be carried out with the fluid fanning surface through leaf as much as possible like this.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one
As shown in Figure 1, 2, take fluid as the impeller of water be example, give that the utility model comprises the wheel hub 2 be fixedly connected with wheel shaft 1, the leaf be fixedly installed on wheel hub 2 outer side wall fans 3 and be arranged on the guide groove 4 that leaf fans 3 surfaces, described leaf fan 3 is provided with guide groove 4 with fluid stress surface of contact, described guide groove 4 is arc, the described guide groove 4 of arc is more than one, and described leaf fan 3 is more than three.The utility model arranges guiding gutter, i.e. guide groove, the active force that increase fluid and leaf are fanned on leaf fan surface, increases the guiding of fluid, thus increases the conversion of fluid dynamic energy, improve the utilization ratio of the energy.Fluid stress surface of contact is the face that fluid and leaf fan 3 forces occurring effects.
Guide groove 4 is genesis analysis on leaf fan 3, and the direction spacing that the spacing between described guide groove 4 is left away with fluid increases gradually.Many guide groove 4 forms gradually open form formula generally, arranges identical with involute.The opening of guide groove 4 own also can be gradually open form formula.
Spacing between the adjacent channels 4 that leaf fan 3 is provided with three guide grooves, 4, three described guide grooves 4 increases gradually with the extension direction of leaf fan 3, and the extension direction of leaf fan 3 is exactly the direction away from wheel hub 2.Guide groove increases gradually in the spacing of leaf fan direction of extension arrangement, can reduce leaf like this and fan outermost stress and deformation, increases leaf fan operating reliability.
As shown in Figure 4, guide groove 4 cross section is arc.The cross section of guide groove can be camber line and straight line surround arc, lower arcuate surface is avoided producing flow-disturbing with fluid contact, reduces the negative effect that guide groove causes current further.
As shown in Figure 5, guide groove 4 cross section is parabolic arch, and the parabola summit of described parabolic arch is positioned at the side away from wheel hub 2 bottom guide groove 4.
Setting the increasing away from the distance of direction apart from wheel hub with fluid of guide groove, the wake flow after avoiding the excessive water conservancy diversion of convection cell to cause water conservancy diversion forms eddy current, and it is unfavorable to cause vane rotary on the contrary.
The cross section of guide groove can also be the parabolic arch that parabola and straight line surround, and parabola summit is positioned at the side away from wheel hub bottom guide groove, when not forming too much eddy current, flow-disturbing, the conversion of energy can be carried out with the fluid fanning surface through leaf as much as possible like this.
Embodiment two
As shown in Figure 3, take fluid as air-flow be example, be with difference with embodiment, it is more that leaf fans 3 numbers, and leaf fan 3 is shorter, but the arrangement regulation of guide groove 4 is identical with embodiment one.
Although be described the utility model with reference to embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and mode of execution, these amendments and mode of execution will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the constituent elements of subject combination layout and/or layout.Except the modification of carrying out constituent elements and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
