一段运行点经常在喘振曲线附近跳动!或者在线上导致喘振阀自动打开。二段运行点一直超过压缩比运行!如何才能降到安全区域?什么原因造成这种情况

几种处理方法1是打开压缩机返回线,工作点会往右移动,回到安全范围2如果原始设计喘振线不准,可以在线重新实验划过,3是查看压缩机是否工艺管路没有完全打开,流量不足排查系统原因

入口流量是否足够,不够就补气。足够的话,保证流量的前提下适当开大防喘阀开度,汽轮机拖动或者调频电机拖动或者带耦合器的机组也可以降低压缩机转速试试。

我们是天然气厂,冷剂压缩机有五种冷剂!氮气,甲烷,丙烷,乙烯,异物烷,压缩机入口压力在180左右,流量140吨每小时,二段出口压力在3800kp

第一加入是我们实验过的!只要开一段喘振阀,运行点就会在安全区内运行,比以前是远离喘振线的。
