离心式压缩机的喘振机理及防范措施

Surge Mechanism and Preventive Measures of Centrifugal Compressor

近些年来,我国化工产业发展较快,在化工生产中离心式压缩机也成为化工生产中比较常用的生产设备。离心式压缩机为速度式压缩机,整体结构比较简单、排气量较大、体积较小且不会受到污染,所产生的气流无脉动,可以提升生产效率,因此在石化行业得到广泛的应用。在化工生产中应用离心压缩机可以提升生产的稳定性与安全性,但是离心压缩机在应用过程中会因为气体压力、流量、温度等方面的变化导致喘振问题。当离心压缩机出现喘振问题时会出现较大的危害,无法保证压缩机使用效率,因此应重点关注并做好处理工作。

In recent years,Chinese chemical industry has developed rapidly,and centrifugal compressors have also become more commonly used production equipment in chemical production.Centrifugal compressor is a speed compressor.Its overall structure is relatively simple,its exhaust volume is large,its volume is small,and it will not be polluted.The generated air flow has no pulsation,which can improve production efficiency.Therefore,it is widely used in the petrochemical industry.The application of centrifugal compressor in chemical production can improve the stability and safety of production,but the surge problem will be caused by the changes of gas pressure,flow,temperature and so on.When the centrifugal compressor has a surge problem,there will be great harm,which cannot ensure the efficiency of the compressor,so we should pay attention to it and deal with it well.
