Abstract
The present invention discloses a kind of sewage pump sealing configuration; Comprise axle sleeve, rotating ring, stationary ring, said axle sleeve is sleeved on the axle, and rotating ring and stationary ring are installed on the said axle sleeve; The end face of said stationary ring and the rotating ring friction pair that partners; Between said rotating ring and the axle sleeve spring is installed, between said rotating ring and the axle rotating ring auxiliary seal ring is installed, the stationary ring auxiliary seal ring is installed between said stationary ring and the casing.Characteristics of the present invention are: simple in structure, sealing is not reliably leaked, and is easy to maintenance, prolonged the operation period, saved recondition expense.
Description
Technical field
The present invention relates to the field of sealing technology of pump, be specifically related to a kind of sewage pump sealing configuration.
Background technique
The sewage pump product is except requiring technological performance; Sealing is the key of sewage pump; Necessary reliability is high, and sewage pump is long Mean time to failure, and the impurity that existing sealing medium commonly used contains has a strong impact on sealability; Unstable working condition needs frequent adjustment and changes filler, and serious wear causes energy input big.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of sewage pump sealing configuration is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of sewage pump sealing configuration; Comprise axle sleeve, rotating ring, stationary ring, said axle sleeve is sleeved on the axle, and rotating ring and stationary ring are installed on the said axle sleeve; The end face of said stationary ring and the rotating ring friction pair that partners; Between said rotating ring and the axle sleeve spring is installed, between said rotating ring and the axle rotating ring auxiliary seal ring is installed, the stationary ring auxiliary seal ring is installed between said stationary ring and the casing.
Characteristics of the present invention are: simple in structure, sealing is not reliably leaked, and is easy to maintenance, prolonged the operation period, saved recondition expense.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Wherein: 1, axle sleeve 2, spring 3, rotating ring auxiliary seal ring 4, rotating ring 5, stationary ring 6, stationary ring auxiliary seal ring.
Embodiment
As shown in Figure 1; The present invention includes axle sleeve 1, rotating ring 4, stationary ring 5, said axle sleeve 1 is sleeved on the axle, and rotating ring 4 and stationary ring 5 are installed on the said axle sleeve 1; The end face of said stationary ring 5 and rotating ring 4 friction pair that partners; Between said rotating ring 4 and the axle sleeve 1 spring 2 is installed, between said rotating ring 4 and the axle rotating ring auxiliary seal ring 3 is installed, between said stationary ring 5 and the casing stationary ring auxiliary seal ring 6 is installed.During work; Rotating ring 4 leans on the pressure of liquid in the closed chamber that its end face is pressed on stationary ring 5 end faces, and on two ring end faces, produce suitable specific pressure with keep one deck as thin as a wafer liquid film and reach the purpose of sealing, clamping element produces pressure; Can make pump under operating condition not; Also keep end face to fit, guarantee that sealing medium does not leak outside, and prevent that impurity from getting into seal face.
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.
