Silicon Carbide Mechanical Seals For Rotating Machinery
Description of Customized SSiC Mechanical Seals:
Mechanical seal is a kind of shaft sealing device rotating the michanery, it is formed by at least a pair of end face perpendicular to the rotation axis, and under the force of fluid pressure and compensation institution elastic force (stone force) and with the cooperation of the auxiliary seal, the faces keep seat and the relativ sliding, to prevent the fluid leakage.
The rotating ring and static ring is generally formed by the group of pure SSiC rings, or one SSiC and the othe is SSiC+C material.
Rotating and static ring: a pair of pure SSiC rings, applicable for strong corrosive medium.
Rotating and static ring: a SSiC ring, and a SiC+C, applicable for the medium easy to vaporized.
Performance advantages of SSiC (Pressureless sintered silicon carbide):
| ♦ High strength |
| ♦ Low density:3.15-3.18 g/cm3 |
| ♦ Max Temperature up to 1650℃ |
| ♦ Low thermal expansion : 4.0 (10-6/℃) |
| ♦ High thermal conductivity:120 W/m°K |
| ♦ High hardness:2800 HV5 |
| ♦ High elastic modulus: 410GPa |
| ♦ Superior chemical stability,resistance to acid and alkali corrosion (incld. hydrofluoric acid) |
Why choose us:
Our pressureless sintered silicon carbide products has high density and high hardness, we can volume produce many kinds of and many shapes of complicated mechanical seals in material of SSiC.
