Description
[technical field]
The utility model relates to a kind of composition system of chemical pump, is specifically related to a kind of chemical pump bearing seal system, belongs to technical field of chemical.
[background technique]
In the industries such as smelting, oil, metallurgy, chemical industry, the medium carried in the production procedure of raw material slurry generally all contains hard granule and the corrosive liquids such as acid solution or alkali lye, and the capital equipment of conveying adopts chemical pump.
General chemical pump causes medium to be revealed because the problems such as equipment part the is aging shaft seal that all there will be in various degree damages in the process of the above-mentioned medium of conveying, or the medium of piping flange joint is revealed, the Korrosionsmedium revealed is once enter bearing bracket by the position such as axle, bearing gland, bearing will inevitably be damaged, cause pump cannot continue normal operation, need to change the parts such as bearing, add maintenance cost, shorten the working life of pump.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel chemical pump bearing seal system, to overcome described defect of the prior art.
[model utility content]
For solving the problem, the purpose of this utility model is to provide that a kind of structure is simple, sealing is reliable and the chemical pump bearing seal system of long service life.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of chemical pump bearing seal system, and it comprises axle, bearing, bearing bracket, outside framework oil seal, bearing gland, bolt, water retaining ring, O type circle and Cock screw; Wherein, described axle is bearing on bearing; Described bearing bracket is set on bearing; Described bearing gland is connected to bearing side, and is connected on bearing bracket by described bolt; Described outside framework oil seal is arranged on described bearing gland; Described water retaining ring is fixed on axle by described Cock screw; Described O type circle is arranged between water retaining ring and axle.
Chemical pump bearing seal system of the present utility model is set to further: be provided with labyrinth seal in described bearing gland, and the radial clearance of labyrinth seal and axle is 0.5mm.
Chemical pump bearing seal system of the present utility model is also set to: described water retaining ring embeds described bearing gland.
Compared with prior art, the utility model has following beneficial effect: the bearing gland of chemical pump bearing seal system of the present utility model adopts labyrinth seal and installed outside framework oil seal, embedded water retaining ring sealing has been installed again after bearing gland, fundamentally stop other hazardous mediums such as extraneous corrosive liquids, mud and enter damage bearing in bearing bracket, ensure that the operation stability of pump, extend the working life of pump.
[accompanying drawing explanation]
Fig. 1 is the structural representation of chemical pump bearing seal system of the present utility model.
[embodiment]
Refer to shown in Figure of description 1, the utility model is a kind of chemical pump bearing seal system, and it is primarily of a few part composition such as axle 1, bearing 2, bearing bracket 3, outside framework oil seal 4, bearing gland 5, bolt 9, water retaining ring 6, O type circle 7 and Cock screw 8.
Wherein, described axle 1 is bearing on bearing 2.Described bearing bracket 3 is set on bearing 2.
Described bearing gland 5 is connected to bearing 2 side, and is connected on bearing bracket 3 by described bolt 9.Be provided with labyrinth seal 10 in described bearing gland 5, labyrinth seal 10 is 0.5mm with the radial clearance of axle 1, this guarantees the reliability of labyrinth seal 10.Further, described labyrinth seal 10 is secondary seal, its sealing by inside bearing bracket 3 through a little lubricant oil of outside framework oil seal 4 seepage, a little hazardous medium simultaneously sealed through the outer seepage inwards of water retaining ring 6 enters bearing bracket 3.This labyrinth seal 10 structure is simple, nothing is worn and torn, power consumption is little, long service life, good seal performance, has saved cost of equipment maintenance, has improve the operational reliability of pump.
Described outside framework oil seal 4 is arranged on described bearing gland 5, prevents lubricant oil inside bearing bracket 3 to outward leakage.
Described water retaining ring 6 is fixed on axle 1 by described Cock screw 8, and it embeds described bearing gland 5.Described O type circle 7 is arranged between water retaining ring 6 and axle 1.The embedded part axial clearance of described water retaining ring 6 on bearing gland 5, radial clearance are all designed to 0.8mm, gap is little, sealing is reliable, stop other hazardous mediums such as extraneous corrosive liquids, mud and enter damage bearing 2 in bearing bracket 3, ensure that the operation stability of pump, extend the working life of pump.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
