Abstract
The invention relates to a multi-end surface combined mechanical seal which comprises a connecting flange, a static ring and a moving ring; water injection holes are arranged in the connecting flange; and the static ring is provided with a plurality of runner holes which are communicated with the water injection holes and one or more first circular grooves which are communicated with the runner holes. Because the static ring is provided with the runner holes which are communicated with the water injection holes and one or more first circular grooves which are communicated with the runner holes, the abrasive surfaces of the static ring and the moving ring are provided with a plurality of end surfaces and a plurality of runners, self-circulating and self-cooling effects are formed, the problems of dry abrasion, no circulation and no cooling of an existing single-end surface mechanical seal are solved, so that the abrasive surfaces of the moving ring and the static ring are always in good lubricated and cooling states.
Description
Technical field
The present invention relates to mechanical seal, relate in particular to a kind of multiterminal face combined machine sealing, be 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 by this invention provides the better mechanical seal structure of a kind of sealability, with further raising and the sealability of improving fluid machinery.
Technological scheme of the present invention 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.
Beneficial effect of the present invention: because one or multi-channel the first circular groove that stationary ring is provided with a plurality of runner holes that are communicated with water injection hole and is communicated with the runner hole, 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 has guaranteed moving, stationary ring is in the good lubricated and state of cooling all the time to flour milling.
The invention will be further described below in conjunction with the drawings and the specific embodiments.
