Reciprocating compressor
Thread Content
The first-stage exhaust pressure of the reciprocating compressor is 2.1 MPa, and the outlet pressure at the second stage is also the same. What’s the reason?
Check the temperature at the secondary outlet; if it is the same as the temperature after primary cooling, then the valve at the secondary outlet is damaged and is not allowing gas to pass through.
It’s very likely that no work will be done at the second stage! The exhaust valve is faulty, or the pressure gauge is faulty!
The tower is empty from a process perspective; one cylinder is sufficient for supply. Once the amount reaching the tower reaches a certain level, the processing will begin
It’s possible that there is a problem with the secondary piston and it isn’t working, or the secondary intake valve is faulty, or the pressure gauge is damaged! A failure of the secondary exhaust valve can cause the temperature of the secondary cylinder to rise continuously.
If it is a two-stage compression system, then the pressure in the process storage tanks and pipelines is low; the pressure will increase once the pressure in those tanks and pipelines rises.
The secondary stage is not working; check the secondary valve
Stage 2 does no work. Check the secondary intake and exhaust temperatures, valve seats, piston rings, etc
