Gas film mechanical seal under special working conditions:

The new food and pharmaceutical industries require mechanical seals to not only reflect the aforementioned advantages of the gas film sealing of the kettle, but also have the characteristics of easy cleaning and sterilization. These requirements need to go through a special structural design to meet. This type of mechanical seal device is used in the following occasions: one is the same as the application of wet-running mechanical seal; second, there is a rotating ring seat on the process medium side to seal it. 358 mechanical seal

Figure 4-33 shows the basic structure of a sterile gas film seal.
