Porous combined sealing plate

Abstract

The invention discloses a porous combined sealing plate. The porous combined sealing plate comprises a roller cooling water sealing ring, a dry grease sealing ring used for lubricating a sealing bearing seat, a bearing seat cooling water sealing ring and an auxiliary plate, wherein the roller cooling water sealing ring, the dry grease sealing ring and a bearing seat cooling water through hole arearranged on the auxiliary plate; and the roller cooling water sealing ring, the dry grease sealing ring and the bearing seat cooling water sealing ring are arranged on the two sides of the auxiliary plate in the thickness direction of the auxiliary plate in a protruding mode. Therefore, by fixing the position of the auxiliary plate, the positions of the roller cooling water sealing ring, the dry grease sealing ring and the bearing seat cooling water sealing ring integrated on the auxiliary plate can be fixed, installation is simple and convenient, installation time and labor force are saved, and installation efficiency is improved; and meanwhile, the problem that the sealing rings are placed wrongly in independent installation is avoided, the sealing effect is effectively guaranteed, and the service life of a sealing member is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, and more specifically relates to a porous combined sealing plate used for the segment bearing seat of a slab continuous casting machine. Background technique [0002] The cooling water and lubricating oil required for the bearing seat of the slab continuous casting machine segment are conveyed through channels formed by the bearing seat support, the connecting plate and the corresponding holes on the bearing seat, and every two holes are connected by a sealing ring. [0003] In the prior art, multiple sealing rings are installed separately. On the one hand, since a segment of a slab continuous casting machine is provided with 84 connecting plates, and one connecting plate is provided with 3-4 sealing holes, the workload of the separate installation method is enormous, and a large amount of labor is wasted and the operation On the other hand, since the diameters of the sealing rings on t...

AI Technical Summary

Problems solved by technology

On the one hand, since a segment of a slab continuous casting machine is provided with 84 connecting plates, and one connecting plate is provided with 3-4 sealing holes, the workload of the separate installation method is enormous, and a large amount of labor is wasted and the operation On the other hand, since the diameters of the sealing rings on the same connection plate are relatively close, if the sealing ring is selected manually, there may be placement errors, which will cause the sealing ring to not correspond to the sealing hole, which cannot guarantee the sealing effect and will reduce the sealing ring. service life
