Abstract
The utility model relates to a mechanical sealing friction pair, comprising a friction pair basal body, a hard alloy sealing ring, and a non-ferrous metal solderable coating. The friction pair basal body and the hard alloy sealing ring are formed into a fixed integral under the action of the solderable coating. The utility model has the advantages of firmness, high durability, mechanical shock resistant, abrasion resistant, and good sealing performance, which can increase the service life by 3-4 times and improve the utilization factor of a mechanical device.
Description
The utility model relates to the seal arrangement on a kind of mechanical component, especially a kind of mechanical seal friction pair.
Rotatable parts are all arranged in many machinery, do not break down and reduce precision, all will on rotatable parts, add seal arrangement, rubber seal is arranged, the steel Sealing is arranged, cemented carbide Sealing etc. is also arranged for the long-term operation that guarantees rotatable parts.The utility model then relates to the mechanical seal friction pair of cemented carbide series, the structure of the mechanical seal friction pair of prior art is by heating friction pair matrix, makes its expansion, hard alloy seal ring is set on the friction pair matrix then, after treating the friction pair cooling, hard alloy seal ring is fixed.The sealing friction pair of existing this structure, because in use, the phenomenon that cemented carbide breaks often appears in the influence of the stressed not even mechanical shock of cemented carbide, influences the normal operation of equipment.
The purpose of this utility model provides a kind of shock resistance, long mechanical seal friction pair of life-span.
The purpose of this utility model realizes in the following manner.In order to improve combining of carbide ring and friction pair matrix, between hard alloy seal ring and friction pair, increase brazing layer, both are fixedly become one.
Figure of description is a structural representation of the present utility model;
With reference to Figure of description the utility model is described in detail.
Mechanical sealing friction pairs of the present utility model. Mainly by friction pair matrix (1), hard Matter alloy sealing ring (2) and soldering layer (3) form. With carbide alloy sealing ring (2) and friction pair matrix (1), by machining accuracy processing, then carbide alloy sealing ring (2) is installed on the friction pair matrix (1) earlier, carries out soldering with non-ferrous metal as brazing material. Make the soldering layer (3) that forms between the two, strong bonded is integral. The employed non-ferrous metal of soldering layer (3) is copper or signal bronze etc.
Embodiment:
Shown in Figure of description, at first, process by required precision hard alloy seal ring and friction pair matrix.Hard alloy seal ring is placed on the friction pair, soldering bar with copper or signal bronze, be placed on the acetylene flame and heat, the soldering bar is melted on the seam of hard alloy seal ring and friction pair, be seeped between both slit and form brazing layer, after cooling, hard alloy seal ring and friction pair matrix just form an integral body.
Mechanical sealing friction pairs of the present utility model can bear bigger mechanical shock in use, does not break, and improve 2～3 times or more than prior art service life, and the utilization rate of plant equipment is greatly improved, and good economic and social profit is arranged.
Claims (2)
1, a kind of mechanical seal friction pair comprises friction pair matrix, hard alloy seal ring and brazing layer, it is characterized in that, hard alloy seal ring is installed on the friction pair matrix, and both are fixed into one by brazing layer.
2, friction pair according to claim 1 is characterized in that fixedly the brazing layer of hard alloy seal ring and friction pair matrix is non-ferrous metal copper or gun-metal etc.
