摘要
大型石油化工装置中,由于离心压缩机控制或保护系统功能失效造成工厂停车和离心压缩机损坏的情况时有发生。针对汽轮机驱动离心压缩机的控制和保护方案进行了研究和总结,介绍了几种离心压缩机相关的仪表控制和保护功能的解决方案,对离心压缩机及其相关设备的测量仪表功能、控制及保护系统的设计方案选择有一定的参考意义。
Factory shutdown and centrifugal compressor destroy occur occasionally due to failure of centrifugal compressor control or protection system function in large petrochemical plants.The control and protection schemes of steam turbine driven centrifugal compressor are studied and summarized.Solutions on instrument control and protection functions for centrifugal compressor are introduced.It has certain reference for the design scheme for the measurement instrument function,control and protection system for centrifugal compressor and relative equipment.
