Abstract
The utility model discloses a novel mechanical seal for a slurry pump. The mechanical seal is formed by connecting an oil seal base and a gland through an inner hexagon screw; a sealing chamber is formed in the mechanical seal; a shaft sleeve is arranged on the sealing chamber; a movable ring is arranged on the shaft sleeve; a sealing ring is arranged on the movable ring and a stationary ring is arranged at the left end of the movable ring; the sealing ring is arranged on the stationary ring; a cavity is formed by the outer surface of the stationary ring and the gland; a rubber isolation sleeve which enables the stationary ring to have better axial compensation capability is arranged in the cavity; one end of the rubber isolation ring is connected with the front end of the stationary ring through a snap ring while the other end of the rubber isolation ring is tightly adhered to the end face at the right end of the pressure cover through a screw ring. According to the mechanical seal for the novel slurry pump, particles cannot enter the groove where the sealing ring is located; blocks cannot be formed by condensing to jam the groove space; the rubber isolation sleeve has better axial stretching capability, so that the floating resistance of the stationary ring is not increased and the axial compensation capability of the stationary ring is not affected; the friction end face of the mechanical seal can be effectively adhered; and the novel mechanical seal for the slurry pump has the characteristics of higher reliability and longer service life.
Description
Technical field
The utility model relates to a kind of seal arrangement technical field, is specifically related to a kind of mechanical seal for pump device that in the higher medium of granule contents such as slag slurry, uses.
Background technique
In Chemical Manufacture; Usually need the higher material of transports particles content (slag slurry); Higher to the employed mechanical seal requirement of conveying equipment (pump), each mechanical seal manufacturing enterprise has designed number of different types slag stock pump and has used mechanical seal for this reason, and is applied in the actual production.Because such mechanical sealing static ring (compensated loop) does not rotate when work, this locates the mobile relatively poor of medium, and particle deposits easily.In the time of the pump stall, particle can get into the groove position at seal ring place, condenses into piece and stops up the groove space, increases the unsteady resistance of stationary ring, can not move axially, and loses compensation ability, thereby mechanical seal was lost efficacy, and causes leakage.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The model utility content
The utility model technical problem to be solved is: to the deficiency of existing technology; Provide a kind of novel slag stock pump to use mechanical seal; This novel slag stock pump uses in the high medium of the slag slurry granule content of the mobile difference of ring with mechanical seal compensation stationary ring; Particle can not get into the groove position at seal ring place, can not condense into piece and stop up the groove space; In addition; Because the rubber separation sleeve has good axial stretching ability, make it can not increase the unsteady resistance of stationary ring and influence the nose balance ability of stationary ring, guarantee that the mechanical seal abrasive end face can effectively fit; Make the slag stock pump higher, longer service life with the reliability of mechanical seal.
For reaching the foregoing invention purpose, the technological scheme that the utility model adopted is: a kind of novel slag stock pump is connected its inner form sealed chamber with gland through socket head screw by oil sealing base with mechanical seal; Sealed chamber is provided with axle sleeve; Said axle sleeve is provided with rotating ring; Said rotating ring is provided with seal ring and left end is provided with stationary ring; Said stationary ring is provided with seal ring, and the outer surface of its stationary ring and gland form cavity; It is characterized in that: be provided with in the said cavity and be used to make stationary ring to have the rubber separation sleeve of good nose balance ability; Said rubber separation sleeve one end is connected in the stationary ring front end through snap ring; The other end compresses applying through threaded collar and gland right-hand member end face.
In sum, a kind of novel slag stock pump that the utility model provided is used mechanical seal, makes the slag stock pump higher with the reliability of mechanical seal, longer service life.
Description of drawings
Fig. 1 is that a kind of novel slag stock pump of the utility model is used the mechanical seal structure schematic representation.
Wherein: 1, oil sealing base; 2, gland; 3, socket head screw; 4, stationary ring; 5, seal ring; 6, threaded collar; 7, rubber separation sleeve; 8, snap ring; 9, rotating ring; 10, axle sleeve; 11, cavity.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done detailed explanation.
As shown in Figure 1, this novel slag stock pump is connected its inner form sealed chamber with gland 2 through socket head screw 3 by oil sealing base 1 with mechanical seal; Sealed chamber is provided with axle sleeve 10; Said axle sleeve 10 is provided with rotating ring 9; Said rotating ring 9 is provided with seal ring 5 and left end is provided with stationary ring 4; Said stationary ring 4 is provided with seal ring 5, and the outer surface of its stationary ring 4 and gland 2 form cavity 11; It is characterized in that: be provided with in the said cavity 11 and be used to make stationary ring 4 to have the rubber separation sleeve 7 of good nose balance ability; Said rubber separation sleeve 7 one ends are connected in stationary ring 4 front ends through snap ring 8; The other end compresses applying through threaded collar 6 and gland 2 right-hand member end faces.
Front at seal ring 5 increases a rubber separation sleeve 7, makes the particle in the medium can not get into seal ring 5 groove positions, place and it is stopped up, to guarantee that stationary ring 4 has good nose balance ability; With snap ring 8 rubber separation sleeve 7 is connected to the front portion of stationary ring 4 by interference fit, with threaded collar 6 rubber separation sleeve 7 is compressed and be attached on the gland 2 right-hand member end faces, make media particle can not get into cavity 11.
In sum, a kind of novel slag stock pump that the utility model provided is used mechanical seal, makes the slag stock pump higher with the reliability of mechanical seal, longer service life.
Though describe in detail in conjunction with the embodiment of accompanying drawing, should not be construed as qualification to the protection domain of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
