5 For a high pressure seal, the sealing ring is to be designed for an external pressure of pa = 200 bar. 27. Influence of the sectional transition on the strength of a carbon ring under external pressure, (a) experimental ring 3; (b) experimental ring 4. (I) carbon ring; (2) housing ring ' only a phenol-resin impregnated carbide can be used. Its pressure resistance was aD = 2500 bar. The torque was transmitted via the carbon by a combined shrinkage/adhesive joint with the metallic housing ring.

4 Leakage There are various causes for face seal leaks. Leakage normally takes place through the radial seal gap formed by the two sliding surfaces. However, faulty static sealing elements, such as damaged O-rings, shrunken sleeves or excessive roughness on their contact surfaces, can open up leakage flow paths. The same applies to faulty compression or shrinkage seatings and to porous seal face materials. 10. For the time being only the primary leakage through the seal gap between the faces of the seals will be considered.

Influence of sectional transi­ tion on the strength of a graphite ring subject to internal pressure, (a) experi­ mental ring 1; {b) experimental ring 2 high ratio a/b = 1-23, the safety factor for ring 2 was still SB = 1*35 but in the case of ring 1 it had dropped to 078 due to the stress con­ centration at G. 5 For a high pressure seal, the sealing ring is to be designed for an external pressure of pa = 200 bar. 27.
