The mechanical face seal device with an insert for the cooling liquid

摘要

A face seal device, comprising a first sliding ring (1), a coaxially with respect to the first sliding ring (1) arranged second sliding ring (2) and a mating ring (3), wherein the sliding rings (1, 2) and the mating ring (3) in each case adjacent sealing surfaces (4a, 4b, 5a, 5b) and wherein the sealing surfaces (4a, 5a) of the sliding rings (1, 2) the sealing surfaces (4b, 5b) of said mating ring (3) are arranged opposite to each other, is, in order to achieve the object, an operation to provide a mechanical face seal assembly of a suitable device, which, according to a problem-free assembly, a high heat resistance and a high service life of the drawing shows, characterized in that between the first sliding ring (1) and the second sliding ring (2) an insert (6) with an inner working surface (7) and an outer working surface (8) is arranged, which cooling fluid, with the sealing surfaces (4a, 4b, 5a, 5b) leads.
