Abstract
The utility model relates to the technical field of motor for submerged pump parts, especially a kind of motor for submerged pump two-lid sealing structure, there is turriform seal body, the bottom of described turriform seal body and top are respectively equipped with lower seal lip and upper sealing lip, the internal diameter of described lower seal lip is identical with the internal diameter of upper sealing lip, the middle part of turriform seal body is also provided with the cone-shaped cavity be connected with upper sealing lip with lower seal lip respectively, injects Food-grade lubricant in described cone-shaped cavity.The good seal performance of this two-lid sealing structure and the life-span longer.
Description
Technical field
The utility model relates to the technical field of motor for submerged pump parts, especially a kind of motor for submerged pump two-lid sealing structure.
Background technology
Motor for submerged pump is one of vitals in beverage machine, is divided into horizontal machine and vertical machine by textural classification.At present, in the motor for submerged pump that market uses, most employing is single lip sealing ring, and sealing property is general and the life-span is not long, can not meet the work requirements of motor for submerged pump.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of good seal performance and life-span longer motor for submerged pump two-lid sealing structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of motor for submerged pump two-lid sealing structure, there is turriform seal body, the bottom of described turriform seal body and top are respectively equipped with lower seal lip and upper sealing lip, the internal diameter of described lower seal lip is identical with the internal diameter of upper sealing lip, the middle part of turriform seal body is also provided with the cone-shaped cavity be connected with upper sealing lip with lower seal lip respectively, injects Food-grade lubricant in described cone-shaped cavity.
Further restriction, top caliber size and the bottom bore of the cone-shaped cavity described in technique scheme are measure-alike, and in the middle part of it, caliber size is greater than its top caliber size.
Further restriction, the cross sectional shape of the lower seal lip described in technique scheme is up-narrow and down-wide isosceles trapezoid, shape at the bottom of the cross sectional shape of the described upper sealing lip bowl that to be periphery reduce successively to the degree of depth of centre; The maximum inner diameter size of lower seal lip and the maximum inner diameter of upper sealing lip measure-alike.
The beneficial effects of the utility model are: motor for submerged pump two-lid sealing structure of the present utility model, structure is simple, easy to use and reliable, by being provided with two measure-alike sealing lips of maximum inner diameter in turriform seal body, and a cone-shaped cavity is provided with between this pair of seal lips, and the top caliber size of cone-shaped cavity and bottom bore measure-alike, Food-grade lubricant is injected in this cone-shaped cavity, not only add sealing, and greatly improve durability, extend useful life, useful life is more than 170% of conventional seals circle on market, meet the work requirements of motor for submerged pump completely.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1.
Label in accompanying drawing is: 1, turriform seal body, 2, lower seal lip, 3, upper sealing lip, 4, cone-shaped cavity.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The utility model motor for submerged pump two-lid sealing structure as depicted in figs. 1 and 2, there is turriform seal body 1, the bottom of turriform seal body 1 and top are respectively equipped with lower seal lip 2 and upper sealing lip 3, the internal diameter of lower seal lip 2 is identical with the internal diameter of upper sealing lip 3, the middle part of turriform seal body 1 is also provided with the cone-shaped cavity 4 be connected with upper sealing lip 3 with lower seal lip 2 respectively, injects Food-grade lubricant in cone-shaped cavity 4.
Wherein, top caliber size and the bottom bore of cone-shaped cavity 4 are measure-alike, and in the middle part of it, caliber size is greater than its top caliber size.The cross sectional shape of lower seal lip 2 is up-narrow and down-wide isosceles trapezoid, shape at the bottom of the cross sectional shape of upper sealing lip 3 bowl that to be periphery reduce successively to the degree of depth of centre; The maximum inner diameter size of lower seal lip 2 and the maximum inner diameter of upper sealing lip 3 measure-alike.
In actual use procedure, Step Shaft on this two-lid sealing structure matches with the afterbody of motor for submerged pump, the axiality of two-lid sealing structure and motor for submerged pump is ensure that, in order to avoid reduce useful life because two-lid sealing structure produces core shift friction because of displacement by higher dimensional accuracy.Two sealing lips that maximum inner diameter is measure-alike are provided with in turriform seal body 1, and between this pair of seal lips, be provided with a cone-shaped cavity 4, and the top caliber size of cone-shaped cavity 4 and bottom bore measure-alike, in this cone-shaped cavity 4, Food-grade lubricant is injected during installation, not only add sealing, and greatly improve durability, extend useful life, useful life is more than 170% of conventional seals circle on market, meets the work requirements of motor for submerged pump completely.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
