Sequence of introducing sealing gas
Thread Content
Why is it necessary to supply the primary seal gas first before supplying the secondary seal gas?
Could you first learn about the functions of the primary and secondary seals?
Could I have a schematic diagram? It makes it easy for friends in other fields to get involved as well: lol – this seems like some kind of code, used by spies; P
Are you referring to dry gas seals? If so, the primary seal gas generally serves to protect the medium; any leaks will enter the flare system via the secondary seal gas or be blocked back by it
Some say to invest in level one first, while others say to invest in level two first
There is isolation gas; introduce the isolation gas first. Supply primary seal gas: use nitrogen as the primary seal gas, connect the flare line, and then supply secondary seal gas
When the pressure of the medium is higher than the nitrogen pressure supplied as the primary seal gas, the medium is switched to be used as the primary seal gas
Prevent unfiltered medium gas from contaminating the dry gas seal
It is crucial to ensure that the pressure of the sealing gas is higher than the pressure of the machine’s systems!
