Embodiment Construction

[0022] Now refer to figure 1 and figure 2 , the mechanical seal arrangement 1 according to the first preferred embodiment of the present invention will be described in detail below. The mechanical seal arrangement 1 seals the fluid chamber 6 against the atmosphere 60 .

[0023] From figure 1 As can be seen in the figure, the mechanical seal 1 is arranged on the rotating shaft 15 and seals the compressor 16 . The compressor compresses the gaseous fluid supplied to the user via discharge line 17 . A branch line 18 branches off from the discharge line 17 and leads to the fluid chamber 6 at the mechanical seal arrangement 1 .

[0024] The mechanical seal arrangement 1 includes a mechanical seal including a rotary slip ring 2 and a stationary slip ring 3 , and a sealing gap 4 is defined between the rotary slip ring 2 and the stationary slip ring 3 .

[0025] The mechanical seal seals the fluid chamber 6 against the atmosphere 60 .

[0026] The rotary mechanical seal 2 is hel...

Abstract

The invention relates to a gas-lubricated slide ring seal arrangement which uses a gaseous fluid as barrier medium, comprising: a slide ring seal with a rotating slide ring (2) and with a static slidering (3) which, between them, define a sealing gap (4), a preload device (5) which preloads the static slide ring (3) in the direction of the rotating slide ring (2), a fluid chamber (6) to which thegaseous fluid can be fed, a first slide ring carrier (20) for holding the rotating slide ring (2), wherein the first slide ring carrier (20) has a first axial surface (21), a second slide ring carrier (30) for holding the static slide ring (3), wherein the second slide ring carrier (30) has a second axial surface (31), wherein the second slide ring (30) and the static slide ring (3) are arrangedso as to be jointly displaceable on a displacement surface (32) in an axial direction (X-X), an axial gap (7) which is delimited by the first axial surface (21) and the second axial surface (31), anda pre-chamber (8) which is formed at the sealing gap (4) of the slide ring seal and which is connected by the axial gap (7) to the fluid chamber (6).

Description

technical field [0001] The present invention relates to a gas lubricated mechanical seal arrangement using a gaseous fluid as a barrier medium, the mechanical seal arrangement having improved fouling resistance. Background technique [0002] Gas lubricated mechanical seals are used, for example, in compressors to seal the drive shaft of the compressor. A gaseous fluid such as air or nitrogen is used as a barrier medium for sealing the sealing gap between a rotating mechanical slip ring and a stationary mechanical slip ring in a gas lubricated mechanical seal. During operation of a mechanical seal arrangement, dirt particles in the form of small solids etc. can enter the seal gap and damage the sliding surfaces of the rotating and / or stationary slip rings. This will reduce the life of the mechanical seal. Contents of the invention [0003] It is therefore an object of the present invention to provide a mechanical seal arrangement which provides improved contamination resi...
