Abstract
The invention discloses a sealing structure of a trash pump. The invention has the technical scheme that the sealing structure comprises a driving seat, a movable ring, a static ring and a spring, wherein the movable ring and the static ring are sleeved on a shaft; the end surface of the movable ring and the end surface of the static ring form a friction pair; the driving seat is sleeved on the shaft; the inside diameter of the driving seat is connected with the outside diameter of the movable ring; a driving boult is arranged on the driving seat and is pressed on the shaft; the spring is arranged between the driving seat and the movable ring; a push ring is arranged between the spring and the movable ring; a movable ring sealing ring is arranged between the movable ring and the shaft; and a static ring sealing ring is arranged between the static ring and a gland. The sealing structure has the characteristics of simple structure, reliability in sealing, prolonged service life and reduced economic input.
Description
Technical field
The present invention relates to the field of sealing technology of pump, be specifically related to a kind of transh pump sealing configuration.
Background technique
The sealing of transh pump always is a problem that makes the researcher have a headache; Along with the expansion of transh pump using scope, this problem is just more outstanding, because the solid particle that transh pump is carried is increasing; The harmfulness of liquid is more and more serious; The working life that the more common silt of these materials all can more seriously shorten sealing to the corrosion and the wearing and tearing of axle and sealing, and in a single day sealing lost efficacy, and leaked just directly to affect the normal operation of pump or even operator's personal safety.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of transh pump sealing configuration is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of transh pump sealing configuration, comprise retainer, rotating ring, stationary ring, spring, and said rotating ring and stationary ring are enclosed within on the axle; The end face of said rotating ring and stationary ring forms a friction pair, and said retainer is enclosed within on the axle, and warp is connected with the rotating ring external diameter in the said retainer; The transmission screw is housed on the said retainer; Said transmission screw in compression is equipped with spring between said retainer and the rotating ring on axle, between said spring and the rotating ring throw-out collar is installed; Between said rotating ring and the axle seal ring of moving ring is installed, the stationary ring seal ring is installed between said stationary ring and the gland.
Warp is connected through spline with the rotating ring external diameter in the said retainer.
Characteristics of the present invention are: simple in structure, sealing is reliable, increases the service life, and reduces economic the input.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Wherein: 1, transmission screw 2, retainer 3, spring 4, throw-out collar 5, seal ring of moving ring 6, rotating ring 7, stationary ring 8, stationary ring seal ring.
Embodiment
As shown in Figure 1, the present invention includes retainer 2, rotating ring 6, stationary ring 7, spring 3, said rotating ring 6 is enclosed within on the axle with stationary ring 7; The end face of said rotating ring 6 and stationary ring 7 forms a friction pair, and said retainer 2 is enclosed within on the axle, and warp is connected through spline with rotating ring 6 external diameters in the said retainer 2; On the said retainer 2 transmission screw 1 is housed, said transmission screw 1 is pressed on the axle, when axle rotates like this; Drive retainer 2 and rotating ring 6, between said retainer 2 and the rotating ring 6 spring 3 is installed, between said spring 3 and the rotating ring 6 throw-out collar 4 is installed; Between said rotating ring 6 and the axle seal ring of moving ring 5 is installed, rotating ring 6 is pressed on the effect that reaches sealing on the stationary ring 7 under the effect of spring force and fluid pressure; Throw-out collar 4 usefulness adjusting screw between retainer 2 and the rotating ring 6 are come Regulation spring 3 pressure size; To regulate the seal degree between rotating ring 6 and the stationary ring 7, between said stationary ring 7 and the gland stationary ring seal ring 8 is installed, prevent that liquid is toward external leakage.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
