Axial displacement of the pyrolysis gas compressor varies with ambient temperature
Thread Content
The shaft displacement of the high-pressure cylinder of the cracking gas compressor in Urumqi Petrochemical Company’s ethylene plant has recently reached as high as -0.4012 mm, which has already reached the alarm threshold; an interlock shutdown will occur when the displacement reaches ±0.6 mm. Recently, the ambient temperature has dropped significantly due to the approaching winter, and as a result the shaft displacement has decreased. Currently, the shaft displacement is -0.3541 mm. Similar phenomena have occurred before as well; experts are requested to provide an explanation.
Have there been any changes in the temperature, flow rate, and composition of the medium entering the compressor? It affects the operating power of the compressor, so there is a change in shaft displacement.
