Embodiment Construction

[0022] will now refer to figure 1 and figure 2 The mechanical seal 1 according to the first preferred embodiment of the present invention will be described in detail.

[0023] like figure 1 As shown, the mechanical seal 1 includes a stationary seal ring 2 and a rotating seal ring 3 . The rotary seal ring 3 rotates together with a rotary component 10 such as a shaft. The sealing rings 2, 3 have sliding surfaces 2a and 3a which face each other and which define a sealing gap 4 between the sliding surfaces 2a and 3a. The mechanical seal 1 seals the area between the first chamber 5 and the second chamber 6 on the rotating shaft 10 . Furthermore, the mechanical seal 1 includes a urging member 7 having a force transmission ring 8 and a plurality of urging springs 9 distributed in the circumferential direction. The force applying member 7 exerts force on the stationary seal ring 2 to make the stationary seal ring 2 abut against the rotating seal ring 3 . X-X represents the axis...

Abstract

The invention relates to a sliding ring comprising a base region (20), a diamond coating (21) that is applied onto the base region (20), and a lubricant coating (22) which is applied onto the diamond coating (21) and which adheres on the diamond coating and fills recesses (23) of the diamond coating (21). The invention further relates to a sliding ring seal comprising at least one sliding ring according to the invention.

Description

technical field [0001] The present invention relates respectively to a seal ring and a mechanical seal comprising a diamond coating and having improved run-in characteristics. Furthermore, the invention relates to a method of manufacturing a sealing ring. Background technique [0002] Seal rings and mechanical seals are known in the art in a variety of configurations. Sealing rings are often subject to high loads during operation, especially high pressure and temperature loads. For this purpose, the prior art (DE 20 2007 016 868 U1) proposes that a sealing ring should be provided with a base body made of carbide material and having a sliding surface of diamond material. It has now been found that, before being put into operation or during operation, due to the microcrystalline structure of the diamond coating, mechanical seals using diamond-coated seal rings may experience Situations of increased leakage. Therefore, due to this leakage possibility, an undesired increase ...
