Is it normal for the exhaust temperature at stage 2 of a reciprocating screw compressor to be lower than that at stage 1?
Thread Content
I would like to ask whether it is normal for the exhaust temperature at the second stage of a reciprocating screw compressor to be lower than that at the first stage Is it a problem with the level 2 cylinder that prevents it from doing work?
How could a screw compressor be reciprocating?
Reciprocating screw compressor? Please give me some advice! !
Points 2 and 3 are correct; what on earth is the original poster talking about? Talking about back-and-forth motion and screws – it seems like these two types of compressors can’t coexist in the same machine, right? ? ?
In addition to compressor issues, the compression ratio also needs to be taken into account!
Reply to 6# yanran88, moderator: Do you mean that this situation occurs when the compression ratio is relatively low? It’s not necessarily a problem with the compressor; could it be that the pressure at the outlet does not reach the designed level?
If the inlet temperature is similar, but the compression ratio of the first stage is higher than that of the second stage, then the exhaust temperature of the second stage will be lower than that of the first stage.
One of your stages must be equipped with an intercooler; in that case, it’s normal for there to be a temperature difference as long as the compression ratio of the second stage is lower than that of the first stage.
