Reciprocating compressor commissioning
Thread Content
Under normal operation, the final exhaust pressure of a reciprocating carbon dioxide compressor is 8.0 MPa; however, during testing (with air), the manufacturer requires this pressure to be 5.0 MPa. Can the final exhaust pressure be increased during testing?
It should still be possible to increase the pressure further, as carbon dioxide has a higher molecular weight and greater density than air. As long as the motor does not experience overcurrent and each section does not see excessive pressure, it is possible to raise the pressure; after all, the closer the outlet pressure is to the actual operating pressure, the more issues related to the compressor will become apparent
According to general analysis, it is possible to increase the pressure, but in principle, it is still necessary to follow the requirements of the manufacturer； If you increase the pressure by yourself, any issues that arise during testing could prove disastrous.
It can be mentioned, but you should do so less frequently. Just make sure to control the heat level yourself.
