Abstract
The utility model relates to an improved impeller, including vane wheel, vane wheel is last to be equipped with the feeding and to remain the ring, the last recess that still is equipped with of vane wheel, the feeding is remained in the ring locates the recess, the terminal surface that the ring was remained in the feeding maintain an equal level with the bottom surface of recess or the terminal surface that the ring was remained in the feeding is less than the bottom surface of recess, forms the wearing layer between the terminal surface of recess and the vane wheel, and vane wheel's center is equipped with the shaft hole, is equipped with the draw -in groove outside the shaft hole, shaft hole and draw -in groove extend away and vane wheel between form and link up the platform, link up a platform periphery and be equipped with the sealing ring. The utility model has the advantages that: the recess can avoid into expanded feeding to remain the ring to the influence of oil pump, and forms the life of wearing layer, multiplicable impeller between the terminal surface of recess and the vane wheel, and the sealing ring of the linking bench of impeller can strengthen the impeller and closely spend with being connected of oil pump.
Description
Technical field
This utility model relating to oil pump technology field, particularly relates to the impeller of a kind of improvement.
Background technology
Impeller is soaking for a long time after in oil, and the charging residual ring that impeller stays owing to making reason can expand, and then blocks oil pump, affect the normal work of oil pump, and impeller is when being immersed in oil pump, owing to the lubrication of oil causes being connected between impeller with oil pump not fastening, easily get loose.Therefore, it should provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The purpose of this utility model is: provide the impeller of a kind of improvement.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of impeller of improvement, including impeller body, impeller body is provided with charging residual ring, and impeller body is additionally provided with groove, and charging residual is located in groove, the end face of charging residual ring maintains an equal level with the bottom surface of groove or feeds the end face bottom surface less than groove of residual ring, forming wearing layer between end face and the impeller body of groove, the center of impeller body is provided with axis hole, and axis hole is externally provided with draw-in groove, axis hole extends out with draw-in groove to be formed between impeller body and is connected platform, and linking platform periphery is provided with sealing ring.
Wearing layer is ceramic material layer.
Sealing ring is Elastic plastic-rubber layer.
Sealing ring is the conical ring reduced for the gradient from back to front.
Due to the application of technique scheme, this utility model compared with prior art has the advantage that
Groove is avoided that the charging residual ring impact on oil pump into expansion, and forms wearing layer between the end face of groove and impeller body, can increase the service life of impeller；And the sealing ring on the linking platform of impeller can strengthen the degree of being completely embedded of impeller and oil pump.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model embodiment one structural representation.
In the figures above: 1-impeller body, 2-charging residual ring, 3-groove, 4-wearing layer, 5-axis hole, 6-draw-in groove, 7-is connected platform, 8-sealing ring.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment.
Embodiment one:
As shown in Figure 1, the impeller of a kind of improvement of this utility model, including impeller body 1, impeller body 1 is provided with charging residual ring 2, groove 3 it is additionally provided with on impeller body 1, charging residual ring 2 is located in groove 3, the end face of charging residual ring 2 maintains an equal level with the bottom surface of groove 3 or feeds the end face bottom surface less than groove 3 of residual ring 2, wearing layer 4 is formed between end face and the impeller body 1 of groove 3, the center of impeller body 1 is provided with axis hole 5, axis hole 5 is externally provided with draw-in groove 6, axis hole 5 extends out with draw-in groove 6 to be formed between impeller body 1 and is connected platform 7, 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 reduced for the gradient from back to front.
Groove 3 is avoided that the charging residual ring 2 impact on oil pump into expansion, and forms wearing layer 4 between the end face of groove 3 and impeller body 1, can increase the service life of impeller；And the sealing ring 8 on the linking platform 7 of impeller can strengthen the degree of being completely embedded of impeller and oil pump.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
