The phase change of the fluid film on the end face of a mechanical seal is often one of the main reasons for its unstable operation. Especially petrochemical I: The mechanical seal for design is particularly prominent in the vapor-liquid two-phase seal. For the light hydrocarbon pumps of alkylation, catalytic cracking and platinum reforming devices, the non-balanced pump is changed to a balanced seal. According to different conditions, different flushing devices are added to increase the service life from a few bu days to one cycle or more.　　234.html,
