Discussion on dry gas seal issues
Thread Content
I have a question regarding dry gas seals that I’d like to discuss with everyone. The differential pressure of the primary sealing gas for the dry gas seal remains unchanged, but the flow rates of the primary and secondary sealing gases suddenly increase. What could be the possible reasons for this? Logically, a sudden increase in the flow rate of the primary and secondary sealing gases, especially fluctuations in the flow rate of the primary sealing gas, should affect the change in the differential pressure of the primary sealing gas, right?
The differential pressure of the primary seal gas is maintained stable by a control valve; a sudden increase in the flow rate of the primary and secondary seal gases is most likely indicative of a fault in the dry gas seal, resulting in an increased leakage rate and possible damage to the seal
