Abstract
The utility model relates to an anti-scaling mechanical sealer for a corrugated pipe relevant to a shaft sealing device in rotary machinery, such as a centrifugal pump, a reaction kettle, etc., which is composed of an axle sleeve 1, a corrugated pipe 4, etc. The outer circle surface of the axle sleeve 1 alternated with the corrugated pipe 4 on the axle sleeve 1 is provided with slots; the slots can be more than one straight slot or spiral slot, and therefore, the water generates tangential flow and a part of axial flow. The utility model reduces the generation of the solid particle deposition and the crystal grain on the metal surface, enlarges the fluid heat transfer coefficient and the water turbulence extent, reduces the variation of the temperature among parts of the fluid, and reduces the generation of the scale. The utility model can be operated under the condition of the natural water in the medium hardness, and the scale on the surface of the corrugated pipe can not affect the compensating elasticity function of the corrugated pipe.
Description
The utility model relates to the anti-incrustation scale bellows mechanical seal of relevant gland seal device in the rotating machineries such as centrifugal pump, reactor.
Existing bellows mechanical seal is used in industry in a large number, the dynamic and static ring material, bellows material and moulding process, unit loading type structure etc. all has mature technology or patent, as patent documentation " simple and easy unit loading type bellows mechanical seal (application number 90222229) ", " bellows moulding seal arrangement (application number 88210280) ", " the corrosion-resistant bellows mechanical seal of BHX type (application number 91222406) ", " propylene pump bellows mechanical seal (application number 92216413) ", the bellows mechanical seal product of " a kind of cantilever pump unit loading type bellow seal (application number 92233855) " and part producer, they are by bellows component, axle sleeve, gland, formations such as seal ring, when water flowing in the space of axle sleeve and bellows formation is cooled off and is incubated, dissolving salt or microimpurity in the water deposit for a long time, crystallization, will in bellows, form the resiliently deformable gap that incrustation scale has been clogged bellows, make bellows lose compensation, buffering, the elastic element effect that loads, make bellows mechanical seal lose seal action, particularly when cooling or insulation water water quality are bad, this fouling is very fast, it shortens the time of the effective seal operation of bellows mechanical seal greatly, and scaling is an existing bellows mechanical seal big technical problem to be solved with topic.
The purpose of this utility model is to provide a kind of special flowing of water generates that makes in axle sleeve and the bellows space, thus the anti-incrustation scale bellows mechanical seal of anti-sealing fouling in the wave plate gap of bellows.The utility model is achieved in that by axle sleeve 1, rotating ring 2, stationary ring 3, bellows 4, gland 5, retainer ring 6, Cock screw 7, retainer ring 8, gland nut 9, positioning block 10 and constitutes, rotating ring 2, stationary ring 3, bellows 4 are enclosed within on the axle sleeve 1 successively, gland 5 links to each other with bellows 4, in the end of axle sleeve 1 retainer ring 6 is arranged, Cock screw 7, retainer ring 8, gland nut 9 are arranged on the retainer ring 6, positioning block links to each other with gland nut 9, it is characterized in that: on the surface, outer garden of the alternate axle sleeve 1 of axle sleeve 1 and bellows 4 groove is arranged.
Said groove can be more than one straight trough or spiral chute.
Advantage of the present utility model is: the lip-deep groove in the outer garden of its axle sleeve is when rotating with axle, make water generates slipstream and section axial stream, on the one hand because souring has reduced the solid particle deposition, reduced of the generation of salt crystal grain in the metal surface, on the other hand, slipstream and axial flow have increased the fluid heat transferring coefficient, increased the less turbulence of water, reduced the temperature contrast between the fluid each several part, local like this high temperature fluid temperature reduces (this zone is positioned near the metal heat transfer face), slightly soluble salt in this partially liq is not easy to reach capacity and promptly begins to generate the state of nucleus crystallization, thereby reduced the generation of incrustation scale, can (move under the natural water condition of calcium oxide content≤200mg/L), the incrustation scale of bellows surface can not influence the compensation elastic reaction of bellows in medium hardness.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the A-A sectional view.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is to be made of axle sleeve 1, rotating ring 2, stationary ring 3, bellows 4, gland 5, retainer ring 6, Cock screw 7, retainer ring 8, gland nut 9, positioning block 10, rotating ring 2, stationary ring 3, bellows 4 are enclosed within on the axle sleeve 1 successively, gland 5 links to each other with bellows 4, in the end of axle sleeve 1 retainer ring 6 is arranged, Cock screw 7, retainer ring 8, gland nut 9 are arranged on the retainer ring 6, positioning block links to each other with gland nut 9, it is characterized in that: on the surface, outer garden of the alternate axle sleeve 1 of axle sleeve 1 and bellows 4 groove is arranged.
Said groove can be more than one straight trough or spiral chute.
Axle sleeve 1 rotates together by retainer ring 8, Cock screw 7 and axle, rotating ring 2 is fixed on the axle sleeve 1 and rotates with axle, stationary ring 3 links to each other with gland 5 together with bellows 4 and does not rotate, rotating ring 2 and stationary ring 3 are under bellows 4 promotes, fit tightly, in rotation, form motive sealing, surface, outer garden at axle sleeve 1, main between axle sleeve 1 and bellows 4, the surface, outer garden of axle sleeve 1, be processed with the straight trough or the spiral chute of given shape, size and quantity, the geomery of the quantity of these grooves, angle (or lift angle) and groove is determined according to the diameter of axle of mechanical seal, the rotating speed of axle.The groove on surface, axle sleeve 1 outer garden makes cooling water (or insulation water) produce slipstream and section axial stream, can prevent that incrustation scale from forming at bellows inside surface.
