Abstract
The silicon carbide ring for the wear-resistant shaft sleeve comprises a sealing ring (1), an expansion ring (4) and a base (6); the sealing ring (1) consists of a sealing end (7), a middle part (8) and a first connecting part (10); the expansion ring (4) is provided with a first groove (3) and a second connecting part (5); a second groove (9) is formed in the base (6); the expansion ring (4) is connected with the first connecting part (10) through a bolt (11); the base (6) is connected with the second connecting part (5) through a bolt (11). The utility model provides the high radiating effect of sealing ring avoids the sealing ring to the influence of axle sleeve expend with heat and contract with cold through the expansion ring, improves life.
Description
Technical Field
The utility model relates to a wear-resisting carborundum ring for axle sleeve.
Background
The shaft seal is effective to prevent high pressure fluid from leaking out of the pump and to prevent air from entering the pump. Although the shaft seal does not occupy a large position in the pump, it is closely related to the shaft seal whether the pump can operate normally. If the shaft seal is not properly selected, not only is frequent maintenance required during operation, and many transported liquids are leaked, but also fire, explosion and toxic accidents can be caused by leaked flammable, explosive and toxic liquids, and the consequences are not reasonable. At present, when the shaft seal is used, the condition of over-high temperature or over-low temperature can be generated, so that the local stress concentration phenomenon is generated, the shaft seal is easy to age and crack, and the equipment safety is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a silicon carbide ring for a wear-resistant shaft sleeve, which comprises a sealing ring, an expansion ring and a base; the sealing ring consists of a sealing end, a middle part and a connecting part I; the expansion ring is provided with a first groove and a second connecting part; a second groove is formed in the base; the expansion ring is connected with the first connecting part through a bolt; the base is connected with the second connecting part through a bolt.
Furthermore, a plurality of radiating grooves are uniformly arranged on the middle part along the circumference.
Further, bolt holes are formed in the expansion ring and the base.
Furthermore, the first connecting part and the second connecting part are trapezoidal, and the outer side edge of the trapezoid is smaller than the inner side edge.
Furthermore, the first groove and the second groove are trapezoidal and are respectively matched with the first connecting part and the second connecting part.
The utility model provides the high radiating effect of sealing ring avoids the sealing ring to the influence of axle sleeve expend with heat and contract with cold through the expansion ring, improves life.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a sealing ring, 2 is a heat dissipation groove, 3 is a first groove, 4 is an expansion ring, 5 is a second connecting part, 6 is a base, 7 is a sealing end, 8 is an intermediate part, 9 is a second groove, 10 is a first connecting part, 11 is a bolt, and 12 is a bolt hole.
Detailed Description
As shown in figure 1, the silicon carbide ring for the wear-resistant shaft sleeve comprises a sealing ring 1, an expansion ring 4 and a base 6. The sealing ring 1 is provided with a sealing end 7, an intermediate part 8 and a first connecting part 10 from top to bottom in sequence. The sealing end 7, the intermediate portion 8 and the first connecting portion 10 are integral. The upper end of the expansion ring 4 is provided with a first groove 3, and the lower end is provided with a second connecting part 5. The first connecting part 10 is matched with the first groove 3. The second connecting part 5 is matched with the second groove 9. The expansion ring 4 is integrated into one piece, and the material is rubber, effectively dissolves the expend with heat and contract with cold that sealing ring 1 during operation produced, avoids the axle sleeve to produce the influence, improves life. The base 6 is provided with a second groove 9. The expansion ring 4 is hermetically connected with the first connecting part 10 through a bolt 11 by adopting a sealing gasket; the base 6 is connected with the second connecting part 5 in a sealing mode through a sealing gasket through a bolt 11.
Evenly establish a plurality of radiating grooves 2 along the circumference on the intermediate portion 8, radiating grooves 2 are the hole that does not run through, are favorable to sealing ring 1 heat dissipation.
The expansion ring 4 and the base 6 are provided with bolt holes 12, so that bolt heads are arranged on the surface of the silicon carbide ring, the surface of the silicon carbide ring is smooth, and the silicon carbide ring is favorable for better operation and attractive appearance.
As shown in fig. 1, the first connecting portion 10 and the second connecting portion 5 are trapezoidal, the outer side of the trapezoid is smaller than the inner side, and the lower bottom of the trapezoid is smaller than the upper bottom. The first groove 3 and the second groove 9 are trapezoidal and are matched with the first connecting part 10 and the second connecting part 5 respectively, and the lower bottom of the trapezoidal shape is smaller than the upper bottom, so that the connection strength is improved.
