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 present invention relates to a gas-lubricated mechanical seal arrangement, which uses a gaseous fluid as a barrier medium. The mechanical seal arrangement includes: a mechanical seal, which includes a rotating slip ring (2) and a fixed slip ring (3). A sealing gap (4) is defined between the rings; a force applying device (5) which applies force to the stationary slip ring (3) towards the rotating slip ring (2); a fluid chamber (6) into which a gaseous fluid can be introduced into the A fluid chamber; a first slip ring carrier (20) for holding said rotary slip ring (2), wherein the first slip ring carrier (20) has a first axial surface (21); a second slip ring The carrier (30) is used to hold the fixed slip ring (3), and the second slip ring carrier (30) has a second axial surface (31), wherein the second slip ring carrier (30) and the fixed slip ring The ring (3) is arranged on the displacement surface (32) together in a manner capable of displacing in the axial direction (X-X); the axial gap (7) consists of the first axial surface (21) and the second axial surface ( 31) defines, and a front chamber (8), which is formed at the sealing gap (4) of the mechanical seal, and which is connected to the fluid chamber (6) via said axial gap (7).

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...
