Application of series air film seal of non-contact mechanical seal for fan:

Figure 4-8 shows a typical series gas film sealing device for hydrocarbon mixtures. This kind of application is seen in pipeline transportation, chemical industry, refining and other occasions. Generally, the operating conditions are limited to 8.3MPa, 260°C, and 152m/s. In this mechanical seal structure, the two mechanical seals in the sealed cavity face the same direction. The leaked gas is discharged into the gas treatment system. Figure 4-9 is a typical series air film seal control system. 202UU mechanical seal
