Abstract
The utility model relates to a sealing device used for a slurry pump bracket. The sealing device comprises a bracket body (1) and a shaft (2). Bearing pressing covers (3) are fixedly connected with the two ends of the bracket body (1). Through holes in a stair-stepping shape are formed in the centers of the bearing pressing covers (3). Shaft sleeves (4) are fixedly connected with the positions where the outer surfaces of the shaft (2) are close to the bearing pressing covers (3). One ends of the shaft sleeves (4) stretch into the through holes and are fixedly connected with the bearing pressing covers (3). Asbestos cushions (5) are arranged on the positions, close to the shaft sleeves (4), between the shaft (2) and the bracket body (1). According to the bearing pressing covers (3), oil seals (6) are arranged on the positions which are close to the shaft sleeves (4) in the through holes. After the sealing device used for the slurry pump bracket is adopted, bearing boxes in an original sealing structure are removed and the sealing structure is simplified. The sealing device is easy to process, and matching between the asbestos cushions, the bearing pressing covers, the oil seals and the shaft sleeves guarantees sealing effect, oil leakages can not happen on the bracket, and site working environment is improved.
Description
Technical field
The utility model relates to a kind of seal arrangement for slag stock pump carriage.
Background technique
The slag stock pump is widely used in the mine, and the industries such as electric power, metallurgy, coal, environmental protection are carried the slurry that contains the abrasion solid particle.The sealing configuration of existing slag stock pump carriage mainly comprises rear bearing gland, interstage sleeve, oil sealing, bearing housing etc.Because seal structure complex, part processing precision are inadequate, cause the carriage leakage of oil serious, and then cause the work on the spot environment abominable.
The model utility content
The purpose of this utility model is the seal structure complex that solves slag stock pump carriage, the problem that difficulty of processing causes greatly the carriage leakage of oil.
The technical solution adopted in the utility model is: a kind of seal arrangement for slag stock pump carriage, it comprises pallet body, axle, described pallet body two ends are fixed with bearing gland, bearing gland central authorities are provided with stepped through hole, the outer surface of described axle is fixed with axle sleeve near the bearing gland place, one end of axle sleeve stretches into through hole and is fixedly connected with bearing gland, is provided with asbestos packing near the axle sleeve place between described pallet body and the axle, and described bearing gland is provided with oil sealing at the inner close axle sleeve place of through hole.
As further improvement of the utility model, described axle sleeve is provided with the groove of embedded O RunddichtringO near the asbestos packing place.
As further improvement of the utility model, described axle sleeve is the stainless steel axle sleeve.
The beneficial effect that the utility model adopts is: after having adopted the seal arrangement of this slag stock pump carriage, removed the bearing housing in the former sealing configuration, simplified sealing configuration, be easy to processing, and the assurance sealing effect matches between asbestos packing, bearing gland, oil sealing, the axle sleeve, carriage can leakage of oil, has improved the work on the spot environment.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is that Fig. 1 is at the enlarged view at A place.
Shown in the figure: 1 pallet body, 2 axles, 3 bearing glands, 4 axle sleeves, 5 asbestos packings, 6 oil sealings, 7 grooves.
Embodiment
Below in conjunction with Fig. 1,2, the utility model is described further.
Such as Fig. 1, shown in 2, a kind of seal arrangement for slag stock pump carriage, it comprises pallet body 1, axle 2, described pallet body 1 two ends are fixed with bearing gland 3, bearing gland 3 central authorities are provided with stepped through hole, the outer surface of described axle 2 is fixed with axle sleeve 4 near bearing gland 3 places, described axle sleeve 4 is the stainless steel axle sleeve, one end of axle sleeve 4 stretches into through hole and is fixedly connected with bearing gland 3, be provided with asbestos packing 5 near axle sleeve 4 places between described pallet body 1 and the axle 2, described bearing gland 3 is provided with oil sealing 6 at inner close axle sleeve 4 places of through hole, and described axle sleeve 4 is provided with the groove 7 of embedded O RunddichtringO near asbestos packing 5 places.After having adopted the seal arrangement of this slag stock pump carriage, remove the bearing housing in the former sealing configuration, simplified sealing configuration, be easy to processing, and the assurance sealing effect that matches between asbestos packing, bearing gland, oil sealing, the axle sleeve, carriage can leakage of oils, improved the work on the spot environment.
