Can a reciprocating compressor surge?

Can a reciprocating compressor surge? Should an anti-choke line be used?

Only the centrifugal type has it, right? Reciprocating types generally have multiple circuits (one circuit for one stage, two circuits for two stages, or two circuits for one stage, etc.), and they are used to start operating or to fine-tune the temperature and compression ratio.

But some reciprocating compressors don’t have multiple return lines.

Sub-zone sub-master edition; proposing such discussion questions is probably to liven up the atmosphere, right: lol

An advanced version merely refers to administrative permissions, not technical proficiency! To know what one knows and to admit what one does not know – that is true knowledge. It’s good to learn to expand on problems; it shows that one is thinking critically and able to draw conclusions from one instance From my personal understanding of Lianhua, he isn’t the type to pretend to know something he doesn’t; instead, he has his own ideas and insights!

Reciprocating machines generally have a return line, but this is not absolute; many compressors used in refineries today feature variable-speed or clearance-adjustment systems, which theoretically allow for the omission of a return line. However, for safety reasons, such a line is usually still retained. The return line is used to control the pressure ratio of the system as well as the amount of fresh hydrogen fed into the system; the compressor for the recycled hydrogen is employed to regulate the amount of recycled hydrogen and its pressure ratio. Surge occurs in centrifuges; this phenomenon does not arise in positive-displacement types. The root cause of surge is when the outlet pressure of the compressor is lower than the system pressure, which leads to gas backflow within the system and thus causes surge in the centrifuge.

The nature of the work is different. It’s actually just a specialized term for a phenomenon. The difference between positive-displacement and turbine types of operation is that neither of them uses the specific term \"surge\": lol

I’m surprised that there are no replies to my post from that day. . . . In short, the structure is different, so the conditions for surge to occur are not present!

Surge will not occur, and there is no need to add a anti-surge line

Without focusing on any specific model for now, let’s discuss what the conditions for surge to occur are As far as I know, there are: 1. Insufficient inlet flow, resulting in surge. 2. The outlet pressure is too low (below the system pressure, preventing pressure from being delivered), resulting in surge. I’m not sure if it’s correct; please advise
