离心式压缩机喘振的原因及预防处理

Causes and Prevention of Surge of Centrifugal Compressor

喘振是离心式压缩机的一种固有特性,也是对机组损害较为严重的事故。如果喘振剧烈,会对机组造成重大的损坏。但是弄清喘振的发生机理,精心维护操作,运行时避免机组进入喘振区,就可有效防止喘振的发生;即使发生喘振,如果正确处理,及时缩短喘振时间,降低喘振程度,则可以避免机组受到损害。

The surge is an inherent characteristic of centrifugal compressor,as well as a serious accident to the unit.If the surge is serious,it will cause significant damage to the unit.If we find out mechanism of surge,and operate carefully,avoid the unit runs into the surge zone,the surge will be prevented effectively;even if the surge occurs,if we treat properly,reduce the surge time and surging levels promptly,the unit can be avoid to damage.
