Compressor surge
Thread Content
For the Shenmu C4 compressor, the anti-surge solution involves monitoring the outlet flow rate and outlet pressure; a return control valve is installed on the outlet return line. If surge occurs in the compressor after it is started up, what could be the reason?
Firstly, this term should be surge. The reason for this is that as the flow rate decreases and the outlet pressure drops, it’s possible for the pressure in the subsequent pipelines to become higher than the pressure at the compressor outlet; in such cases, the fluid may flow back. When the flow rate increases again, forward flow resumes, and these alternating periods of forward and reverse flow can cause severe damage to the equipment. Therefore, protective measures such as surge valves are used in the surge zone to prevent surge from damaging the machinery
Which ITCC is being used – GE’s or Triconex? Is a 3500 model being used for vibration detection?

Anti-surge control for centrifugal compressors generally requires monitoring the inlet flow rate, which serves as the basis for such control. What is the solution in the original proposal?
Didn’t understand? Isn’t it normal for a compressor to surge occasionally? Do we need an anti-suffocation line, and what’s the purpose of it?
I think the same way, but the equipment manufacturers say that testing at the outlet yields the same results as testing at the inlet. Personally, I wonder if testing at the outlet might reveal a situation where surge has already occurred yet the flow rate hasn’t changed.
If it goes into surge, it can easily damage the compressor, right?
