China Patent No. CN 203362600 U application discloses that a kind of water pump vane, comprise wheel disc and blade, blade comprises one group of short blade and group leader's blade, and these two groups of blades are disposed in an evenly spaced relation on wheel disc, linear leaf and short blade be arc shaped blade and the radian of short blade slightly larger than the radian of linear leaf, this invention makes the water conservancy efficiency of impeller be greatly improved, and add the flow that impeller drives water, improve water lift of pump, but, it in the course of the work, the flowing state of current and the setting of blade shape, blade is made to have larger frictional loss, and blade can produce certain cavitation phenomenon after working for a long time.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide one effectively can alleviate the frayed degree of blade, prevents the water pump blade wheel that blade cavitates.
The technical solution of the utility model is: a kind of water pump blade wheel, comprise wheel disc and blade, described wheel disc is provided with connecting shaft portion, described blade is evenly distributed on wheel disc around axle center, connecting shaft portion, described blade comprises linear leaf and short blade, described linear leaf comprises straightway and arc, described straightway is connected with connecting shaft portion, described blade comprises upper surface and lower surface, described lower surface abuts with wheel disc, described straightway is arranged along lower surface towards the distortion of upper surface direction, described arc has been wholely set curved part in straightway opposite end, described curved part is set to arc and described curved part curvature is greater than arc curvature, described curved part bending direction is identical with arc bending direction, described short blade is identical with straightway shape and described short blade is connected in connecting shaft portion, described short blade is between adjacent two panels linear leaf.
By adopting technique scheme, blade comprises linear leaf and short blade, linear leaf includes straightway and arc and arc is arranged near wheel disc edge away from connecting shaft portion, both ensure that blade had larger Driving force to water, turn avoid and produce excessive resistance, thus improve flow and the lift index of water pump, reduce the energy loss in working procedure, improve the operational efficiency of water pump; Straightway and short blade are arranged towards the distortion of upper surface direction by blade lower surface, farthest can ensure that the flowing state of blade passage and current is close, thus make blade be subject to the degradation degree of water little, reduce the frayed degree of blade, and the working efficiency of impeller can be improved; Arc has been wholely set curved part in straightway opposite end, and when water washes away blade, major part water flows to curved part, only has the swiped through blade of fraction to the backflow of blade movement opposite direction, arranges curved part, significantly reduce the backflow phenomenon of water pump.
The utility model is set to further: described linear leaf and short blade quantity are set to 8 respectively and described linear leaf and short blade interval are evenly distributed on wheel disc.
By adopting technique scheme, linear leaf and short blade quantity are set to 8 respectively and described linear leaf and short blade interval are evenly distributed on wheel disc, ensure that impeller has the suitable number of blade, effectively improve flow and the lift of water pump, increase the working efficiency of water pump.
The utility model is set to further: described linear leaf and short blade with not and wheel disc in being wholely set.
By adopting technique scheme, linear leaf and short blade with not with wheel disc in being wholely set, make water pump vane manufacture easy to process, and add the work rigidity of impeller.
The utility model is set to further: outside described linear leaf and short blade, figure is provided with epoxy resin layer respectively.
By adopting technique scheme, outside linear leaf and short blade, figure is provided with epoxy resin layer respectively, effectively can prevent blade from easily being damaged by cavitation erosion, make blade there is slight cavitation erosion small holes, thus reduce the generation of the phenomenon of the operating life of impeller.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model water pump blade wheel.
In accompanying drawing, 1. wheel disc; 2. connecting shaft portion; 3. blade; 31. linear leafs; 311. arc; 3111. curved part; 312. straightway; 32. short blades.
Embodiment
A kind of water pump blade wheel, comprise wheel disc 1, connecting shaft portion 2 and blade 3, wheel disc 1, connecting shaft portion 2 and blade 3, all in integrally casting molded design, facilitate the casting of water pump vane, substantially increase manufacturing efficiency.
Blade 3 comprises linear leaf 31 and short blade 32, linear leaf 31 comprises arc 311 and straightway 312, straightway 312 designs near connecting shaft portion 2, arc 311 away from connecting shaft portion 2 near wheel disc 1 edge designs, straightway 312 is arranged with the direction distortion of wheel disc 1 opposite end towards connecting shaft portion 2 by wheel disc 1, short blade 32 is set to distorted shape and consistent with straightway 312 length, meet the flowing state of current, thus reduce blade 3 washing away by water, under having the situations such as solid particle in water, greatly reduce the frayed degree of blade 3, thus increase the working life of blade.
Arc 31 near wheel disc 1 marginal end be provided with curved part 3111 and described curved part 3111 and arc 31 in being wholely set, described curved part 3111 is set to arc and the curvature of curved part 3111 is greater than the curvature of arc 31, described curved part 3111 bending direction is identical with arc 31 bending direction, when water flows to blade 3 position, major part water can flow in curved part 3111, only have fraction water to wash away blade 3 to reflux, greatly reduce the backflow phenomenon in water pump operation process.
The setting of linear leaf 31, ensure that linear leaf 31 is cast conveniently, easily shaping, simultaneously, linear leaf 31 comprises arc 311 and straightway 312, in pump working process, blade 3 promotes water, the trend at close wheel disc 1 edge because centrifugal action has of the water in impeller, now, arc 311 has larger Driving force compared with straightway 312, and the resistance being subject to water is little, such setting, both ensure that blade had larger Driving force to water, turn avoid and produce excessive resistance, thus improve flow and the lift index of water pump, reduce the energy loss in working procedure, improve the operational efficiency of water pump.
Linear leaf 31 and short blade 32 are crisscross arranged and axis along connecting shaft portion 2 is evenly distributed on wheel disc 1, it is eight that long and short blade quantity is all selected, the interval security protection form of deviated splitter vane, both ensure that water pump vane had enough numbers of blade, prevent again the blocking to impeller channel, and contribute to final result water pump vane outlet diffusion problem.
The outside of blade 3 is coated with epoxy coating, and epoxy coating can protect blade 3 not cavitated, and prevents blade there is slight cavitation erosion small holes, thus improves the operating life of impeller.
