Description
Technical field
This utility model belongs to the technical field of reaction sintering silicon carbide ceramic, has particularly related to a kind of reaction-sintered
Silicon carbide ceramic impeller.
Background technology
Impeller refers to the wheel disc equipped with movable vane, again the general name of finger wheel dish and the moving blade being installed on it.Impeller is pump
Critical component, the purpose using impeller is to make energy convert between " kinetic energy of fluid " and " mechanical energy ".Along with science and technology
Development, pump is widely used in the fields such as oil, mine, metallurgy, light industry, chemical industry, environmental protection, pharmacy, electric power, can carry difference
Liquid or solid matter.Owing to the use environment of pump is different, therefore the most identical to the performance requirement of impeller of pump.The most right
In mine, chemical industry, metallurgy, environmental protection, the impeller of pump in the field such as electric power, it is necessary to there is excellent wear-resistant, decay resistance,
Can meet working condition demand, improve impeller service life, reduce application production cost.
Silicon carbide reaction-sintered has high intensity, high rigidity, the excellent properties such as high temperature resistant, wear-resistant, corrosion-resistant and good
The performances such as antioxidation well, anti-thermal shock, have been successfully applied to metallurgy, industrial chemicals processing, high corrosion and high abrasive fluids thing
Multiple fields such as the conveying of matter, mechanical seal, automobile, papermaking, Aeronautics and Astronautics.
In view of the excellent properties of silicon carbide reaction-sintered, the impeller being in adverse circumstances operating mode has used reaction-sintered carbon
SiClx ceramic material manufactures.For the different types of structure of impeller, due to himself structure, once grouting is used to become
After type, solidification, the demoulding, in addition it is also necessary to its blade and reinforcement are recycled Digit Control Machine Tool and is machined out processing, thus drop
Low production efficiency, adds production cost.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of improvement by structure, at injection forming, admittedly
After change, the demoulding, it is not necessary to its camber blades and reinforcement utilize Digit Control Machine Tool be machined out the reaction-sintered processed again
Silicon carbide ceramic impeller.
For solving above-mentioned technical problem, the technical solution of the utility model is: reaction sintering silicon carbide ceramic impeller, bag
Including: impeller body, the front of described impeller body is provided with camber blades, and the back side of described impeller body is provided with reinforcement,
Described impeller body be provided centrally with axis hole, described axis hole offers keyway;Have on the cross section of described camber blades
Gradient, the cross section of described reinforcement has gradient.
Further, the side of the cross section of described camber blades has gradient, or the cross section of described camber blades
Both sides all there is gradient.
Further, the side of the cross section of described reinforcement has gradient, or the two of the cross section of described reinforcement
Side all has gradient;Described reinforcement is desirably a plurality of, arranges radially.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
The side of the cross section of the camber blades of impeller has gradient, or the both sides of the cross section of camber blades all have
Gradient;The side of the cross section of reinforcement has gradient, or the both sides of the cross section of reinforcement all have gradient;This structure
On improvement be more beneficial for the demoulding after injection forming, and after impeller injection forming, it is not necessary to the camber blades to impeller
And reinforcement recycling Digit Control Machine Tool is machined out processing, it is only necessary to utilize milling machine etc. that the keyway on axis hole is carried out machine and add
Work processes, the reaction sintering silicon carbide ceramic impeller of this structure, improves production efficiency, and drop during manufacturing
Low production cost.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, reaction sintering silicon carbide ceramic impeller, the front of impeller body 2 is provided with multiple bending
Blade 1, the side of the cross section of camber blades 1 has gradient, and inclination angle is α, or the both sides of the cross section of camber blades 1 are all
Having gradient, the inclination angle of both sides can be identical, it is also possible to different;The confession impeller axle that is provided centrally with at impeller body 2 passes
Axis hole 3, axis hole 3 offers keyway 4, keyway 4 is connected with the impeller axle adaptation through axis hole 3;The back of the body at impeller body 2
Face is provided with reinforcement 5, and the side of the cross section of reinforcement 5 has gradient, and inclination angle is β, or the cross section of reinforcement 5
Both sides all have gradient, and the inclination angle of both sides can be identical, it is also possible to different, reinforcement 5 has multiple, and arranges radially
Row.
The process producing reaction sintering silicon carbide ceramic impeller of the present utility model is described: the raw material that will prepare
Slurry is injected in required mould, cured after, carry out demoulding process, i.e. can get the biscuit of silicon carbide ceramic impeller;Leaf
Wheel biscuit is dried, utilizes milling machine etc. to be machined out processing to the keyway 4 on axis hole 3, and now, the structure of impeller is i.e. satisfied to be set
Meter requirement, directly carries out reaction-sintered process, just can obtain required product.
