Dry gas seal flow rate
Thread Content
I want to ask all the seniors. Our factory's dry gas seals are divided into drive end and non-drive end. The first-level sealing gas uses the process gas exported from the third stage of the synthetic compressor. The primary sealing gas pressure and flow rate of the dry gas seal are normal. But the flow rate of the secondary sealing gas is a bit high. But the pressure is normal. Although it does not affect production (the traffic is not chained), I still want to know why the traffic is high. There is also a pneumatic diaphragm regulating valve on the balance pipe of the primary sealing gas that works normally. The electronic transmitter (electronic pressure gauge) on the balancing tube is out of range. The normal value is 0.1MPa, but sometimes it is normal, and sometimes it goes out of range. My novice guess is that there is water in the pipes. . It's just a guess, I hope you can give me an accurate answer.
Is there water in the process gas? This seems impossible. It seems that it is not good for the compressor to carry liquid. Check the instrument first if it exceeds the range. Occasionally, if it exceeds the range and the flow is unstable, then check the pipeline. If there is an opportunity, perform maintenance. refer to
Generally speaking, an increase in the primary leakage volume indicates a problem with the primary seal, and a decrease in primary leakage volume indicates a problem with the secondary seal. From what you said, there should be no problem with the seal. Does a high secondary buffer air flow indicate a problem with the flow meter? There is also a pneumatic diaphragm regulating valve on the balance pipe of the primary sealing gas that works normally. The electronic transmitter (electronic pressure gauge) on the balancing tube is out of range. (Try to drain the dry air and seal the first-level buffer air at the bottom of the filter. )
