Structure of a series type rubber air film seal

We can divide it according to the characteristics of the working medium and the process structure of the mechanical equipment. What are the structural forms of the rubber air film seals for fans? DSH Seals tells you the structural forms of the air film seals for the special rubber seals for fans. : Rubber single-end seal, rubber double-end seal, tandem rubber seal, tandem rubber air membrane seal with intermediate labyrinth seal. Today, we will share with you what are the characteristics of the structure of the single-end air film seal in the special rubber seal for fans?

The structure diagram of the tandem rubber air film seal, this type of sealing structure is a kind of air film seal structure with high operational reliability. As a standard sealing structure in the field of process gas delivery, the tandem rubber gas membrane seal has a simple structural design and requires only a relatively simple gas assist system.

In the structure of the tandem rubber air membrane seal, two separate non-contact rubber mechanical seals are placed one behind the other to form a secondary seal. The medium side seal (main seal) and the atmosphere side seal (secondary seal or secondary seal) can withstand the full pressure difference. In operation, the seal on the media side is exposed to the full differential pressure. Leaks between the media side seal and the atmosphere side seal can be directed into the flare port through port "C". The pressure on the atmospheric side seal is the same as the torch pressure, so the medium is a safe seal to ensure that the medium will not leak into the atmosphere.

The structure of this tandem rubber gas membrane seal is most suitable for use in mechanical equipment of gas compressors that allow trace amounts of process gas to enter the environment, but do not allow gas to enter the hazardous process inside the machine.
