Cold knowledge of seals: the correlation between the seal ring and the seal compressor

  In heel-in-sealing equipment, seals are widely used. All kinds of seal rings, the shape seal ring is the most commonly used, the shape seal

ring has the characteristics of compact structure, simple manufacture, repetitive disassembly and installation, good sealing effect, low cost,

etc. It is a  highly adaptable seal, so the shape seal ring It is widely used in various mechanical equipment.

  In vacuum equipment, the sealing performance of the sealing ring is directly related to the safety and working performance of the equipment.

  In static sealing, the compression of the sealing ring generally comes from the pre-tightening force of the bolt on the flange, but in some

cases, A certain part of the sealed cavity needs to be removed or loaded during work. Due to space constraints, there can be no screw

disassembly process when loading or unloading. Therefore, in order to achieve the sealing performance of the cavity and the need for removal

at any time, a corresponding seal compactor is required.

The structure and principle of the seal compressor:

1. Sealing compressor structure: mainly composed of 1 cavity base, 2 pressing mechanisms, 1 sealing pressing plate plug-in module etc.

2. The working principle of the seal compactor: The plug-in module of the seal press plate is inserted into the gap between the cavity base and

the compaction wheel of the compaction mechanism, and the compaction mechanism shaft is rotated to drive the compaction wheel to rotate

to make the long axis of the oval section of the compaction wheel When one side turns to the sealing pressure plate, the pressure wheel will

push the sealing pressure plate to compress the rubber sealing ring. In the same way, when the short axis of the elliptical section of the

compression wheel turns to the sealing pressure plate, the compression wheel will loosen the sealing pressure plate and the rubber sealing

ring will also be loosened.
