Abstract
The utility model discloses a kind of impeller, comprise impeller body (1), described impeller body (1) is provided with the residual ring of a charging (2), on described impeller body (1), be also provided with a groove (3), the residual ring of described charging (2) is located in groove (3); The end face of the end face of the residual ring of described charging (2) the charging residual ring (2) equal or described with groove (3) bottom surface is lower than groove (3) bottom surface.Above-mentioned impeller can be avoided blocking oil pump and normally work to ensure oil pump.
Description
Technical field
The utility model relates to an accessory of automobile fuel pump the inside, is specifically a kind of impeller.
Background technique
Impeller is working of plastics, and it is injection molded by injection machine, therefore can a residual tubular body on impeller (being that material feeding mouth stays), be impeller cutting off after this tubular body.The impeller of said structure has the following disadvantages in actual using process: after the impeller of said structure soaked in the oily borough chief time, can expand in the residual ring portion of charging position on the impeller being connected with tubular body, thereby block oil pump, and then affect the normal work of oil pump.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of and can avoid blocking oil pump to ensure the impeller of the normal work of oil pump.
The technical solution of the utility model is, a kind of impeller is provided, and comprises impeller body, and described impeller body is provided with the residual ring of a charging, is also provided with a groove on described impeller body, and the residual ring of described charging is located in groove; The end face of the end face of the described residual ring of the charging charging residual ring equal or described with groove floor is lower than groove floor.
The degree of depth of described groove is 0.15-0.16mm.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
The residual ring of charging of the utility model impeller is located in groove; The end face of the end face of the described residual ring of the charging charging residual ring equal or described with groove floor is lower than groove floor, like this, even if the residual ring of charging on the impeller that impeller is connected with tubular body after soaking in the oily borough chief time expands, also be still positioned at groove, can not block oil pump, thereby ensure the normal work of oil pump.
As improvement, the degree of depth of described groove is 0.15-0.16mm.Even if impeller soaks for a long time, still can not exceed 0.15mm yet, therefore, and this groove this groove that can ensure also can not emerge after the residual ring of charging expands, thus the normal work of oil pump ensured.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model impeller.
Shown in figure 1, impeller body, 2, the residual ring of charging, 3, groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of impeller of the utility model, comprises impeller body 1, and described impeller body 1 is provided with the residual ring 2 of a charging, is also provided with a groove 3 on described impeller body 1, and the residual ring 2 of described charging is located in groove 3; The end face of the end face of the residual ring 2 of the described charging charging residual ring 2 equal or described with groove 3 bottom surfaces is lower than groove 3 bottom surfaces, and its further groove 3 can be circle or square groove.
The degree of depth of described groove 3 is 0.15-0.16mm.
Below be only described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
Claims (2)
1. an impeller, comprise impeller body (1), described impeller body (1) is provided with the residual ring of a charging (2), it is characterized in that: on described impeller body (1), be also provided with a groove (3), the residual ring of described charging (2) is located in groove (3); The end face of the end face of the residual ring of described charging (2) the charging residual ring (2) equal or described with groove (3) bottom surface is lower than groove (3) bottom surface.
