Overpressure issue during the operation of hydrogen compressors
Thread Content
Colleagues, I currently have a hydrogen compressor here that pressurizes the hydrogen gas produced by hydrogen extraction and separation for use in the methanol synthesis process. Currently, the pressure in row 2 is above the acceptable limit, which causes the pressure in row 3 to also reach its upper limit. This also leads to an increase in system pressure; the pressure in the three rows is nearly 0.2 MPa higher than the system pressure, and this issue becomes more apparent as the frequency of operation of the hydrogen compressor increases. Has anyone else encountered this situation? Is there a good way to solve this? Thank you!
It is necessary to conduct a disassembly inspection once for reference.
Thank you, it has been disassembled. The problem is resolved after recovery.
Check the secondary exhaust valve and the tertiary intake valve
