Preventive measures of centrifugal compressor in small air separation unit

Centrifugal compressor, sometimes suddenly produce strong vibration in the production process, gas medium flow and pressure also appear substantial pulsation, and accompanied by periodic dull "call" sound, as well as airflow fluctuations in the network caused by "huffing" "huffing" strong noise, this phenomenon is known as the centrifugal compressor wheezing conditions in small air separation unit.

According to the production experience, Dear Air Separation finds the cause of the development of anti-surge specific methods, part of the gas venting method, part of the gas reflux method, change the compressor operating speed method.
