Abstract
The utility model relates to a sealing device for a pump, in particular to a single-end surface mechanical sealing device specially used for a driving shaft for the pump above the ground. The single-end surface mechanical sealing device for the pump comprises a fastening driving block sheathed on the driving shaft for the pump, and is characterized in that the driving shaft for the pump is respectively sheathed with a fixed ring sealing gasket and a movable ring sealing ring; the fixed ring sealing gasket is embedded with a fixed ring abrasion block; the movable ring sealing ring is arranged between a movable ring abrasion block and a sealing ring press plate; and the rear end of the movable ring abrasion block is contacted with the fixed ring abrasion block. The utility model has the characteristics of being good in sealing effect, not slipping, being reasonable in structure and convenient for use, and the like.
Description
Technical field
The utility model relates to a kind of Sealing used for pump, especially relates to a kind of pump that is exclusively used on the ground with the single mechanical end face seal device on the live axle.
Background technique
As everyone knows, traditional pump that is exclusively used in all is single spring Double End with the mechanical seal device on the live axle mostly, lean on to such an extent that be that the magnitude of interference of rubber o-ring is held axle tightly and driven whole sealing rotating ring, though it is simple in structure, but sealing effect is unsatisfactory, in use, because the compressive strain of rubber is big, make easily between axle and the rotating ring and skid, make seal failure.
Summary of the invention
The utility model mainly is at the above-mentioned technical problem of existing in prior technology, a kind of good sealing effect is provided, is difficult for skidding, pump rational in infrastructure single mechanical end face seal device.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of pump single mechanical end face seal device, comprise and be set in pump with the fastening driving block on the live axle, it is characterized in that described pump is with being arranged with stationary ring sealing gasket and seal ring of moving ring on the live axle respectively, be embedded with on the stationary ring abrading block on the described stationary ring sealing gasket, described seal ring of moving ring is arranged between rotating ring abrading block and the seal ring pressing plate, and described rotating ring abrading block rear end contacts with the stationary ring abrading block.The structure of the utility model mechanical seal device is the single end face medium-tight, and assembly has comprised seal ring of moving ring, stationary ring sealing gasket, spring, anti-rotation fixed block, pressing plate etc.; This device belongs to spring in the running and drives the rotation direction running of rotating ring abrading block with axle, rubs between rotating ring abrading block and the stationary ring abrading block, has alleviated the moment of torsion dynamics when starting greatly.
As preferably, described pump is with being arranged with spring on the live axle, and described spring is between seal ring pressing plate and fastening driving block.Seal ring of moving ring has spring to compensate freely at axial wearing clearance, and feature is that the length of spring compressed rotating ring makes the surface of contact between stationary ring and the rotating ring reach tight combination, and it is little to form resistance, bears the high characteristics of pressure.
As preferably, described fastening driving block and pump are embedded with stop pin with being provided with straight keyway between the live axle in the described straight keyway.The stop pin that is embedded in the straight keyway has played the effect of anti-rotation effectively, and is simple in structure, easy to use.
As preferably, described seal ring of moving ring adopts the carbofrax material manufacturing, and described stationary ring sealing gasket adopts the Hardmetal materials manufacturing.This mechanical single seal mainly is used in clean waterpump and sewage pump class, seal ring of moving ring is selected carbofrax material for use, the stationary ring sealing gasket is selected the YG8 Hardmetal materials for use, because the sewage pump class all has the silt particle medium, so with friction block is high hardness material, general mechanical single seal all is direct contact water and silt particle, and just external mounted is general
Therefore, the utlity model has good sealing effect, be difficult for skidding, characteristics such as rational in infrastructure, easy to use.
Description of drawings
Accompanying drawing 1 is that a kind of structure of the present utility model is cutd open plan view.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1, a kind of pump single mechanical end face seal device, comprise the fastening driving block 1 that is set on the pump usefulness live axle 10, pump is with being arranged with stationary ring sealing gasket 2 and seal ring of moving ring 3 on the live axle respectively, be embedded with on the stationary ring sealing gasket that seal ring of moving ring is arranged between rotating ring abrading block 5 and the seal ring pressing plate 6 on the stationary ring abrading block 4, rotating ring abrading block rear end contacts with the stationary ring abrading block.Pump is with being arranged with spring 7 on the live axle, spring is between seal ring pressing plate and fastening driving block.Fastening driving block and pump are with being provided with straight keyway 8 between the live axle.Be embedded with stop pin 9 in the straight keyway.Seal ring of moving ring adopts the carbofrax material manufacturing, and the stationary ring sealing gasket adopts the Hardmetal materials manufacturing.
The structure of the utility model mechanical seal device is the single end face medium-tight, and assembly has comprised seal ring of moving ring, stationary ring sealing gasket, spring, anti-rotation fixed block, pressing plate etc.; This device belongs to spring in the running and drives the rotation direction running of rotating ring abrading block with axle, rubs between rotating ring abrading block and the stationary ring abrading block, has alleviated the moment of torsion dynamics when starting greatly.Seal ring of moving ring has spring to compensate freely at axial wearing clearance, and feature is that the length of spring compressed rotating ring makes the surface of contact between stationary ring and the rotating ring reach tight combination, and it is little to form resistance, bears the high characteristics of pressure.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
