What are the signs of failure in the primary and secondary seal gases of a compressor’s dry gas seal? ?
Free adult websites still exist today; the poems inscribed on their walls all express regret
It would be best to send a schematic diagram and refine the issue further to facilitate discussion. What does \"failure\" in the question mean? Please make it explicit as well, thank you! If toxic and harmful substances leak, things will get serious. Also, inter-stage leakage can cause overpressure in the previous stage and a decrease in efficiency. For reference.
If the primary sealing gas fails, it’s possible that the rotating and stationary rings are worn out, resulting in a failed seal. Does the secondary sealing gas generally refer to the isolation gas? If so, it’s possible that the lubricant could contaminate the seal
The flow rates of primary and secondary leak gases increase
