摘要
”四合一”压缩机组是双加压法硝酸生产中的核心设备，其控制与联锁保护设计较为复杂，控制系统需满足较高的安全等级要求。本文对Siemens PCS7系统在”四合一”压缩机上的应用进行了详细介绍。
The compressor unit in ＂Four in one pattern＂ is the core equipment of nitric acid manufacturing by using the dou- ble-pressurizing method, its design for control and interlocking protection is more complicated, the control system needs to satisfy the requirements of higher safety level. The application of Siemens PCS7 system to the ＂Four in one pattern＂ compressor is introduced in detail in this paper.
