Abstract
The utility model discloses a kind of water pump vane structure, comprise wheel disc, with the integrated blade of wheel disc and be arranged on the axis hole of taking turns disk center; Blade is made up of arcuate portion and straight section, and arcuate portion is connected on wheel hub, and straight section is away from wheel hub side; The width of arcuate portion is increased to its root gradually by top, and straight section is vertical with wheel disc; The radian of the face side of arcuate portion is greater than the radian of the back side of arcuate portion; Wheel disc is provided with stiffening rib integrated with blade lower end, the end face of stiffening rib and the end face of straight section in the same plane.
Description
Technical field
The utility model relates to water pump field, especially a kind of water pump vane structure.
Background technique
The blade that conventional water pump vane comprises axis hole, wheel hub and is connected on wheel hub, blade is the smooth surface of certain radian.Level and smooth cambered surface blade can reduce the resistance to current in the process of water flow, but under the prerequisite of identical circumferential radius and same rotational speed, the flow of arc surface type impeller and lift are all less than normal, can not meet high-lift and requirement that is large discharge.
Model utility content
For above-mentioned deficiency of the prior art, the utility model provides a kind of water pump vane structure of high-lift and large discharge.
For above-mentioned deficiency of the prior art, the technological scheme that water pump vane structure that the utility model provides adopts is: comprise wheel disc, with the integrated blade of wheel disc be arranged on the axis hole of taking turns disk center; Blade is made up of arcuate portion and straight section, and arcuate portion is connected on wheel hub, and straight section is away from wheel hub side; The width of arcuate portion is increased to its root gradually by top, and straight section is vertical with wheel disc; The radian of the face side of arcuate portion is greater than the radian of the back side of arcuate portion; Wheel disc is provided with stiffening rib integrated with blade lower end, the end face of stiffening rib and the end face of straight section in the same plane.
The beneficial effects of the utility model are: when blade carries out fluid transport, the curved portion of blade can reduce the resistance to current in the process of water flow, and straight section has blade than all-arc structure to the larger Driving force of water under the prerequisite of identical circumferential radius and same rotational speed, effectively can improve flow and the lift index of water pump; The setting of stiffening rib can make blade have larger intensity.

Fig. 2 is the stereogram of the impeller of water pump vane structure.
Wherein, 1, wheel disc; 2, blade; 21, straight section; 22, arcuate portion; 23, face side; 3, stiffening rib; 4, end face; 5, axis hole; 6, wheel hub.
Embodiment
Below embodiment of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
The structural representation of water pump vane structure is shown with reference to figure 1, Fig. 1; As shown in Figure 1, this water pump vane structure comprises wheel disc 1, with the integrated blade 2 of wheel disc 1 be arranged on the axis hole 5 at wheel disc 1 center; Blade 2 is made up of arcuate portion 22 and straight section 21, and arcuate portion 22 is connected on wheel hub 6, and straight section 21 is away from wheel hub 6 side.
When blade 2 carries out fluid transport, the curved portion of blade 2 can reduce the resistance to current in the process of water flow, and straight section 21 has the larger Driving force of the blade 2 pairs of water than all-arc structure under the prerequisite of identical circumferential radius and same rotational speed, effectively can improve flow and the lift index of water pump.
In order to make the flow of water pump and lift index reach optimization, the length of preferred straight section 21 equals the length of arcuate portion 22.
The width of arcuate portion 22 is increased to its root gradually by top, and straight section 21 is vertical with wheel disc 1, and its width is constant all the time to its root by end face.After arranging like this, can ensure that blade 2 root blade 2 when being subject to comparatively mass-flow impact can not be truncated.
As shown in Figure 2, the radian of the face side 23 of arcuate portion 22 is greater than the radian of the back side of arcuate portion 22; Wheel disc 1 is provided with stiffening rib 3 integrated with blade 2 lower end.Adopt in such a way, can increase the intensity of blade 2, increase blade 2 carries the impact force compared with mass-flow, improves the working life of blade 2.
Width and the thickness at the tip of general blade 2 are all narrow, when transmitting, current throw away in the blades installation chamber that enters water pump from the edge of blade 2, along with the water thrown away in installation cavity of current gets more and more, the pressure that blade 2 tip is subject to can be increasing, make the most advanced and sophisticated easily damage of blade 2, so be disposed on the same plane with the end face of stiffening rib 3 by the end face 4 of the straight section 21 of blade 2.
As shown in Figure 1, in order to reduce the pressure that blade 2 tip is subject to further, during use, the extended surface of the end face 4 of preferred straight section 21 and being arranged between 30 ° ~ 40 ° by the angle α between extended surface and the tangent line of wheel disc 1 intersection point.
The thickness of stiffening rib 3 equals the thickness of wheel disc 1, and equals 1/3rd of blade 2 height.
Although describe in detail embodiment of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
