Abstract
The invention discloses a seal structure of a floating ring. The seal structure comprises a floating ring, a floating sleeve, a supporting spring, a pressure relief ring and a shaft sleeve, wherein the shaft sleeve is sleeved on a shaft; the floating sleeve and the pressure relief ring are installed on the shaft sleeve; the floating ring is installed between the floating sleeve and the shaft sleeve; and the supporting spring is installed in a space formed by the floating sleeve and the floating ring. The seal structure disclosed by the invention has the advantages of simple structure, reliable operating, automatic alignment, prolonged service life and reduced economic investment.
Description
Technical field
The present invention relates to the field of sealing technology of pump, be specifically related to a kind of float ring sealing structure.
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 float ring sealing structure is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of float ring sealing structure; Comprise floating ring, floating bushing, supported spring, pressure release ring, axle sleeve; Said axle sleeve is sleeved on the axle; Floating bushing, pressure release ring are installed on the said axle sleeve, between said floating bushing and the axle sleeve floating ring are installed, in the space that said floating bushing and floating ring form supported spring is installed.
Characteristics of the present invention are: simple in structure, running is reliable, has the advantage of self-aligning, increases the service life, and reduces economic the input.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Wherein: 1, floating ring 2, floating bushing 3, supported spring 4, pressure release ring 5, axle sleeve.
Embodiment
As shown in Figure 1; The present invention includes floating ring 1, floating bushing 2, supported spring 3, pressure release ring 4, axle sleeve 5; Said axle sleeve 5 is sleeved on the axle; Floating bushing 2, pressure release ring 4 are installed on the said axle sleeve 5, between said floating bushing 2 and the axle sleeve 5 floating ring 1 are installed, in the space that said floating bushing 2 and floating ring 1 form supported spring 3 is installed; Floating ring 1 end face is realized axial seal with contacting of floating bushing 2 end faces, and the throttling that the narrow gap that axle sleeve 5 outer round surface and floating ring 1 internal circular surfaces form produces realizes radial seal.
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.
