Description

Be applicable to the mechanical sealing element of large particle slurry machine
Technical field
The utility model relates to a kind of Sealing, especially relates to a kind of mechanical sealing element being applicable to large particle slurry machine.
Background technique
At present, large particle slurry machine in mine, steel-making, river management, urban environmental protection, the field such as port dredging application more and more wider, because the fluid carried in these fields contains more large particulate matter, the relatively common liquid of these materials to the corrosion of sealing and wearing and tearing all more serious, higher requirement is improve to Sealing.
The mode that existing large particle slurry secret envelope is commonly used has packing seal and mechanical seal two kinds, and packing seal directly contacts with axle due to filler, regularly or irregularly must change axle sleeve, has increased and decreased cost, but also there is the shortcomings such as electric efficiency is low, power consumption is large; Mechanical seal is more and more applied on large particle slurry machine because of advantages such as its good airproof performance, leakage rate are few, the utility model patent being 200620254557.6 as application number discloses a kind of movable mechanical sealing member for high-concentration flushing-free assembling type slurry pump, solve a large amount of water problem of the outer Rinsing unit consumption of tradition, but it is high to there are the wearing and tearing of large particle slurry to Sealing, make Sealing temperature height fragile, Sealing uses common spring simultaneously, easily stuck, rate of fault and maintenance rate high, add cost.
Model utility content
The purpose of this utility model is, the generate heat problem such as fragile Sealing, rate of fault and maintenance rate high high for the wearing and tearing of large particle slurry to Sealing of existing large particle slurry machine mechanical sealing element existence, the mechanical sealing element being applicable to large particle slurry machine provide a kind of long service life, steady quality, effectively preventing Sealing stuck.
The technical scheme in the invention for solving the technical problem is:
A kind of mechanical sealing element being applicable to large particle slurry machine, comprise axle sleeve, rotating ring, stationary ring, O type circle, gland, positioning block, screw, jump ring, transmission ring, wavy spring and limited ring, it is characterized in that: described rotating ring is arranged on axle sleeve, and between rotating ring and axle sleeve, be provided with O type circle, wavy spring, O type circle can strengthen the shock-absorbing capacity between rotating ring and axle sleeve, and then improve the sealability of Sealing, wavy spring can effectively prevent Sealing stuck, reduce rate of fault and the maintenance rate of Sealing, extend the working life of Sealing, described stationary ring is arranged on the side of rotating ring, and and axle sleeve, gland is adjacent, described gland is arranged on axle sleeve, and on gland, be provided with O type circle, positioning block, cooling liquid entrance, bolt, positioning block can improve the fastness of gland on axle sleeve, cooling liquid is input between rotating ring and stationary ring by cooling liquid entrance and carries out pressurization cleaning, reduce large particle slurry to the wearing and tearing of Sealing, reduce the temperature of Sealing, extend the working life of Sealing further, bolt can improve the fastness after gland installation, and then improve the fastness of Sealing, described transmission ring is arranged on axle sleeve by screw, and the side of transmission ring is provided with jump ring, jump ring can avoid transmission ring position to offset, and then the performance of Sealing can be improved, described positioning block is fixed by screws on transmission ring, positioning block can improve the fastness of gland further, described limited ring is arranged on the side of rotating ring, and be fixed by screws on axle sleeve, limited ring can improve rotating ring position fastness, rotating ring adopts Integral alloy design, improve the performance of Sealing, steady quality, long service life, reduce cost.
O type circle is provided with between described stationary ring and gland.
Described bolt is interior hexagonal cylindrical hook bolt.
Beneficial effect: the utility model is provided with wavy spring between rotating ring and axle sleeve, can effectively prevent Sealing stuck, rotating ring adopts Integral alloy design, improve the performance of Sealing, drive rotating ring to rotate by axle sleeve, cooling liquid to be input between rotating ring and stationary ring by cooling liquid entrance and to carry out pressurization cleaning, reduction large particle slurry is to the wearing and tearing of Sealing, reduce the temperature of Sealing, extend the working life of Sealing.
