Description
Technical field
The utility model is related to a kind of stainless steel water pump vane wheels.
Background technology
The shape and size of water pump vane have substantial connection with pump performance, and the blade on water pump vane determines dampening
The working efficiency of impeller of pump.Water pump vane is mainly cylinder iron made.At present, part also uses two-phase for the impeller in power station
Stainless steel 1.4462 is made, and the material is more expensive, and material hardness is in HRC20 hereinafter, the impeller is more for water quality sand content
Environment in when, the water outlet position serious wear of blade causes pump efficiency to reduce after being worn due to blade.The prior art
Be using spray-on coating method increase blade wearability, however the thickness of spray-on coating in below 0.2mm abrasion resistant effects not
Significantly, if increasing coating layer thickness, coating easily comes off.
Utility model content
The utility model aims to solve the problem that the technical issues of above-mentioned mentioned, provides a kind of stainless steel water pump vane wheel, increases leaf
The wearability of piece.
The utility model is realized by following technical solution：
A kind of stainless steel water pump vane wheel, including end cap, several blades and chassis, several blades are fixed on end lid and bottom
Between disk, the center on end cap and chassis is equipped with the connecting hole passed through for drive shaft, and the blade includes ontology and goes out positioned at ontology
The wear-resisting portion of water end (W.E.), the wear-resisting portion are welded on ontology, the end cap, ontology and chassis for stainless steel material integrally casting into
Type forms.
Further, the wear-resisting portion is formed by wear-resistant material built-up welding.
Further, the arc-shaped sheet of the blade.
Further, the center on the end cap and chassis extends outward to form the supporting part with bearing fit, the branch
Bearing portion is equipped with boron carbide seal wear-resistant layer.
Further, several blades are divided into two layers, and separator disc, the plane of the separator disc are equipped between two layers of blade
It is vertical with the axis of connecting hole, two layers of blade stagger setting.
Advantageous effect is：Compared with prior art, a kind of stainless steel water pump vane wheel passes through the water outlet of the ontology in blade
Weld wear-resisting portion, improve the hardness of the most fast water outlet of damage in impeller, effectively prevent blade is too fast to be worn, and with spray
Painting is compared, and the wear-resisting portion of welding will not fall off.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is the structure diagram of impeller in the utility model embodiment one；
Fig. 2 is the structure diagram of blade in the utility model embodiment one；
Fig. 3 is the structure diagram of impeller in the utility model embodiment two.
Specific embodiment
Embodiment one
As depicted in figs. 1 and 2, a kind of stainless steel water pump vane wheel, it is described several including end cap 1, several blades 2 and chassis 3
Blade 2 is fixed between end cap 1 and chassis 3, and blade 2 is set for individual layer, and the center on end cap 1 and chassis 3 is equipped with wears for drive shaft
The connecting hole crossed, the blade 2 include ontology 21 and positioned at the wear-resisting portions 22 of 21 water outlet of ontology, and the wear-resisting portion 22 is welded on
On ontology 21, the end cap 1, ontology 21 and chassis 3 are formed for stainless steel material integrally casting shaping.Pass through the sheet in blade 2
Wear-resisting portion 22 is welded in the water outlet of body 21, improves the hardness of the most fast water outlet of damage in impeller, effectively prevent blade 2 too fast
It is worn, and compared with spraying, the wear-resisting portion 22 of welding will not fall off.
Further, the wear-resisting portion 22 is formed by wear-resistant material built-up welding.Specific practice is, in 2 water outlet of prophyll piece,
The raw material of 3mm thickness are removed, are about 70mm, and 4~5mm of build-up wear-resistant material thickness in the position, polishing welding seams to prophyll wheel
Shape, Low Temperature Heat Treatment improve surfacing hardness, which can reach HRC50.Certainly, those skilled in the art are in this programme
Introduction under, the recess portion of the wearing layer of accommodating monoblock using the wearing layer of monoblock as wear-resisting portion 22, can also be set in ontology 21,
Then the welding wear-resistant layer of monoblock is connected on recess portion.
Further, the 2 arc-shaped sheet of blade.Blade 2 reduces resistance to water-flow along direction of rotation arc-shaped bend,
Reduce the wear extent of the grains of sand and blade 2 in water simultaneously.
Further, the center on the end cap 1 and chassis 3 extend outward to form with the supporting part of bearing fit 4, it is described
Supporting part 4 is equipped with boron carbide seal wear-resistant layer 41.By setting boron carbide seal wear-resistant layer 41, the wearability of supporting part 4 is improved,
Ensure that impeller operates steadily.
Further, the blade 2 that is, when water pump rotates forward, goes out to be obliquely installed at least at impeller outlet from impeller
The water and the grains of sand of mouth outflow can all obtain the axial component velocity for being directed toward 1 direction of end cap, make the grains of sand distribution that impeller outlet flows out
It is even, so as to reduce the impact and abrasion that the grains of sand excessively concentrate blade 2.
Embodiment two
As shown in figure 3, it is two layers that several blades 2, which divide, separator disc 5, the separator disc 5 are equipped between two layers of blade 2
Plane it is vertical with the axis of connecting hole, two layers of blade 2 is staggered.By setting two layers of blade 2, and two layers of blade 2 is handed over
Mistake setting, makes it improve working efficiency.Part reference implementation example one is not specified in the present embodiment.
Above example is only to illustrate the technical solution of the utility model and is not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
