Abstract
The utility model provides a multi-end-face combined mechanical seal comprising a connection flange, a static ring and a movable ring, wherein the connection flange is provided with a water injection hole; the static ring is provided with a plurality of runner holes communicated with the water injection hole, and one or a plurality of first annular grooves which are communicated with the runner holes. The static ring is provided with the plurality of runner holes communicated with the water injection hole, and one or the plurality of first annular grooves which are communicated with the runner holes, so that the opposite grinding faces of the static ring and the movable ring are provided with a plurality of end faces and a plurality of runners to form self-circulation and self-cooling effects; and the problems of dry friction, no circulation and no cooling of an existing multi-end-face combined mechanical seal can be solved, and the opposite grinding faces of the static ring and the movable ring are at good lubricating and cooling states all the time.
Description
Technical field
The utility model relates to mechanical seal, relates in particular to a kind of multiterminal face combined machine sealing, is applicable to the fluid machinery industry.
Background technique
The desulfur pump that separates desulfurization such as the cigarette ash that is used for power plant, be usually used in harmful material fermentation and the reactor of carrying and underflow pump etc., because the particularity of medium can not directly be lubricated, dry combustion method and dry grinding often appear in the stationary ring of existing single mechanical end face seal structure and the sealing surface of rotating ring, damage sealing surface, cause medium to be revealed, make the harmful slurries and mortar and the harmful material befouling environment that produce.
Summary of the invention
Technical problem to be solved in the utility model is to provide the better mechanical seal structure of a kind of sealability, with further raising and the sealability of improving fluid machinery.
The technical solution of the utility model is: a kind of multiterminal face combined machine sealing, comprise adpting flange, stationary ring and rotating ring, described adpting flange is provided with water injection hole, one or multi-channel the first circular groove that described stationary ring is provided with a plurality of runner holes that are communicated with water injection hole and is communicated with the runner hole.
For further improving sealability, described rotating ring preferably also is provided with one or multi-channel second circular groove relative with the first circular groove of stationary ring.
the beneficial effects of the utility model: one or multi-channel the first circular groove that is provided with a plurality of runner holes that are communicated with water injection hole and is communicated with the runner hole due to stationary ring, rotating ring also is provided with one or multi-channel second circular groove relative with the first circular groove of stationary ring, thereby what make stationary ring and rotating ring forms multiterminal face disjunctor stationary ring and the multiterminal face disjunctor rotating ring with multiple tracks end face and a plurality of runners to flour milling, form self-loopa, self cooled effect, overcome existing single mechanical end face seal dry friction, without circulation, non-refrigerated problem, guaranteed moving, stationary ring is in the good lubricated and state of cooling all the time to flour milling.
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Description of drawings
A kind of embodiment's of Fig. 1 the utility model overall structure schematic diagram.
Fig. 2 is the structural representation of a kind of embodiment of stationary ring in Fig. 1.
Fig. 3 is that the A of Fig. 2 is to the distribution schematic diagram of runner hole and the first circular groove.
Fig. 4 is the structural representation of a kind of embodiment of rotating ring in Fig. 1.
Embodiment
as Fig. 1, Fig. 2, Fig. 3, shown in 4, the sealing of a kind of multiterminal face of the present embodiment combined machine, comprise locking ring 1, adpting flange 2, stationary ring 3, rotating ring 4 and the transmission axle sleeve 6 that drives rotating ring 4 operations, stationary ring 3 is equipped with adpting flange 2, both junctions are by corresponding O RunddichtringO 7 sealings, rotating ring 4 is sealed by corresponding O RunddichtringO 7 with the junction of transmitting axle sleeve 6, transmit axle sleeve 6 fixing by locking ring 1, be provided with wavy spring 5 between rotating ring 4 and transmission axle sleeve 6, stationary ring 3 is oppositely arranged with rotating ring 4 and forms mill and regulated both balance and wearing and tearing by wavy spring 5.Described adpting flange 2 is provided with water injection hole 10, one or multi-channel the first circular groove 9 that stationary ring 3 is provided with a plurality of runner holes that are communicated with water injection hole 10 8 and is communicated with runner hole 8, rotating ring 4 is provided with one or multi-channel second circular groove 11 relative with the first circular groove 9 of stationary ring 3.The stationary ring of the present embodiment is circular groove together with rotating ring all is provided with.Certainly also the multiple tracks circular groove can be set according to seal request, rotating ring also can not established circular groove.
During operation, inject lubricant oil, lubricant oil injects the lubricating cavity between the second circular groove of the first circular groove 9 of stationary rings 3 and rotating ring 4 through the water injection hole 10 of adpting flange and runner hole 8, realize dynamic and static the lubricated and cooling of sealing surface (to flour milling) of going back, prevent both sealing surface dry combustion method and dry grinding, damage sealing surface, cause medium to be revealed.
Claims (2)
