Abstract
The invention relates to an improved impeller. The improved impeller comprises an impeller body. A feeding residue ring is arranged on the impeller body, a groove is further formed in the impeller body, the feeding residue ring is annularly arranged in the groove, the end surface of the feeding residue ring and the bottom surface of the groove or the end surface of the feeding residue ring is lower than the bottom surface of the groove, a wear-resistant layer is formed between the end surface of the groove and the impeller body, a shaft hole is formed in the center of the impeller body, a slot is formed outside the shaft hole, the shaft hole and the slot extend out to form a joining table with the impeller body, and a seal ring is arranged on the periphery of the joining table. The improved impeller provided by the invention has the advantages that the groove can prevent the expanded feeding residue ring from affecting an oil pump, and the wear-resistant layer is formed between the end surface of the groove and the impeller body, so that the service life of the impeller is prolonged; and the seal ring on the joining table of the impeller can enhance the connecting compactness of the impeller and the oil pump.
Description
Technical field
The present invention relates to carburetion pump technical field, more particularly to a kind of improved impeller.
Background technology
Impeller is residual due to making the charging that stays of reason on impeller after long-time is soaked in oil
Stay ring to expand, and then block oil pump, affect the normal work of oil pump, and impeller is immersed in oil
When in pump, do not fasten because the lubrication of oil causes to connect between impeller and oil pump, easily release.
Therefore, it should a kind of new technical scheme is provided and is solved the above problems.
The content of the invention
The purpose of the present invention is：A kind of improved impeller is provided.
For achieving the above object, the technical solution used in the present invention is：
A kind of improved impeller, including impeller body, impeller body is provided with charging residual ring,
Groove is additionally provided with impeller body, charging residual is located in groove, the end face of charging residual ring
With the bottom surface that the end face of the bottom surface of groove or charging residual ring is less than groove, the end face of groove
Wearing layer is formed between impeller body, the center of impeller body is provided with axis hole, and axis hole is externally provided with
Draw-in groove, axis hole is extended out to be formed between impeller body with draw-in groove and is connected platform, linking platform periphery
It is provided with sealing ring.
Wearing layer is ceramic material layer.
Sealing ring is Elastic plastic-rubber layer.
Sealing ring is the conical ring for reducing for the gradient from back to front.
Due to the application of above-mentioned technical proposal, the present invention has compared with prior art following excellent
Point：
Groove is avoided that the charging into expansion remains impact of the ring to oil pump, and the end face of groove
Wearing layer is formed between impeller body, the service life of impeller can be increased；And the rank of impeller
Connecing the sealing ring on platform can strengthen the degree of being completely embedded of impeller and oil pump.
Description of the drawings
Accompanying drawing 1 is the structural representation of the embodiment of the present invention one.
In the figures above：1- impeller bodies, 2- charging residual rings, 3- grooves, 4- wearing layers,
5- axis holes, 6- draw-in grooves, 7- linking platforms, 8- sealing rings.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment one：
As shown in figure 1, a kind of improved impeller of the present invention, including impeller body 1, impeller body
1 is provided with charging residual ring 2, and groove 3 is additionally provided with impeller body 1, and charging residual ring 2 is located at
In groove 3, the end face of charging residual ring 2 is low with the end face of the bottom surface of groove 3 or charging residual ring 2
Wearing layer 4, impeller sheet are formed between the bottom surface of groove 3, the end face and impeller body 1 of groove 3
The center of body 1 is provided with axis hole 5, and axis hole 5 is externally provided with draw-in groove 6, axis hole 5 and draw-in groove 6 extend out with
Linking platform 7 is formed between impeller body 1, linking platform 7 periphery is provided with sealing ring 8.
Wearing layer 4 is ceramic material layer.
Sealing ring 8 is Elastic plastic-rubber layer.
Sealing ring 8 is the conical ring for reducing for the gradient from back to front.
Groove 3 is avoided that the charging into expansion remains impact of the ring 2 to oil pump, and the end of groove 3
Wearing layer 4 is formed between face and impeller body 1, the service life of impeller can be increased；And impeller
Sealing ring 8 on linking platform 7 can strengthen the degree of being completely embedded of impeller and oil pump.
Above-described embodiment technology design only to illustrate the invention and feature, its object is to allow ripe
The personage for knowing technique will appreciate that present disclosure and implement according to this, can not be limited with this
Protection scope of the present invention processed.All equivalence changes made according to spirit of the invention are repaiied
Decorations, all should be included within the scope of the present invention.
