Abstract
The utility model discloses a lubricating machinery sealing pair which mainly consists of a dynamic ring(1), a static ring(2), an auxiliary rubber lip seal(3) and an O-shaped ring. The sealing pair is coupled with a frequent used machinery sealing component. The ring shape sealed operating plane of the dynamic ring(1) and the main body ring direction of the operating plane remain under eccentric status. The eccentric ring shape sealed operating plane(5) is opened with a ring shape oil tank(6). The utility model disposes the difficult problem that the frequent used machinery seal can not be lubricated and also overcomes the problem that leakage problem exists due to the gaps of the static ring and dynamic ring. Therefore, the utility model can be extensively used as the leakage seal of pumps and kettles.
Description
Technical field
The utility model relates to a kind of mechanical seal.
Background technique
General mechanical seal at present, rotating ring is a seal shaft, it is to be fixed on the axle tightly by 0 shape of mechanical sealing linkage ring vestibule circle or other colloid Sealing, to stop medium by the gap seepage between axle and mechanical sealing linkage ring hole, stationary ring then is to lean on the overcoat Sealing of self that the hole that stationary ring is installed is sealed, but there is certain interval in the hole of stationary ring with axle, can cross flow medium, so, the function of the sealing seal operation plane of dynamic and static ring of mechanical seal that places one's entire reliance upon.And when being the rotary work state by the mechanical seal of plane sealing, the dynamic and static ring sealing working surface is coaxial concentric work, do not have oil groove again and deposit lubricant oil, thereby, even being immersed in the oil pocket, dynamic and static ring can not be lubricated, because in case Lubricants is arranged or the medium that sealed is a seepage when entering sealed working face, under given conditions, submersible pump for example infiltrates WATER AS FLOW MEDIUM and enters motor cavity and just cause motor to burn out, and entire equipment can not be worked.Simultaneously also can be because of under unlubricated working state, the long-term dry friction of dynamic and static ring working surface makes the working life of mechanical seal pair can not be very long.
Summary of the invention
The utility model aims to provide and a kind ofly can solve the lubricated lubricating mechanical sealing pair that seals of guaranteeing again, makes mechanical seal prolong working life, reduce its seal failure rate of corollary equipment for it.
The technical solution of the utility model is as follows: the lubricating mechanical sealing pair, mainly form by rotating ring and stationary ring, form the hoop plane sealing between rotating ring and the stationary ring, the hoop sealed working face of rotating ring and its main ring are to being eccentric state, and eccentric hoop has annular oil groove on sealed working face.
Stationary ring is sleeved in the auxiliary lip glue envelope, and O type snare is contained on the lip of auxiliary lip glue envelope and is inlaid in the vestibule of stationary ring, and the epipharynx of auxiliary colloid lip envelope forms auxiliary seal to stationary ring.
Key of the present utility model is that the rotating ring main body of mechanical seal becomes eccentric structure with its sealed working face, simultaneously on eccentric sealed working surface, driven oil groove, make sealed working face be divided into two eccentric annular working face contact stationary ring sealed working faces like this by an annular working face of original structure, more steady than a plane contact, thus sealing effect improved.Simultaneously the eccentric energy of rotation of the annular oil groove of sealed working face by the rule lubricant oil that will remain in plane one side is constantly received to scrape and is stored in the oil groove, constantly discharge again, make and form the very thin film lubrication of one deck between the dynamic and static ring sealing face, reduce the frictional damping of mechanical sealing surface, improved the working life of mechanical seal pair.Stationary ring of the present utility model has adopted colloid lip auxiliary seal, be sealed and matched and axle also carried out the hoop sealing in the Hole Passage of Workpiece wrapping stationary ring, make medium seldom can alleviate the working load of mechanical seal widely by the gap overcurrent seepage of stationary ring vestibule and between centers.For guaranteeing that the colloid lip seals permanent proper functioning, with the O shape circle hoop solid envelope lip that contracts, make it proper functioning again.

Embodiment
According to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, rotating ring 1 cooperates with other member of conventional mechanical, stationary ring 2 is placed in the auxiliary colloid lip envelope 3, O shape circle 4 is sleeved on the epipharynx of auxiliary colloid lip envelope 3, the epipharynx and the shaft sealing of the auxiliary colloid lip envelope 3 of lock ring are played and the vestibule of stationary ring 2 and the seal action between centers crack.The hoop sealed working face 5 of rotating ring 1 and its main ring are to being eccentric state, have annular oil groove 6 on the hoop sealed working face 5, the rotation that is close together of the sealed working face of rotating ring 1 and stationary ring 2, at this moment the hoop sealed working face 5 of rotating ring 1 is done the eccentric rotation of hoop, oiling agent just has an opportunity constantly to enter the stationary ring sealing plane, be lubricated with the hoop sealed working face 5 of rotating ring 1, and make the annular oil groove 6 of the hoop sealed working face of rotating ring 1 be filled with minor amounts of lubricants.
Claims (2)
