制氧设备主要包括空气压缩系统、空分塔系统、氧气压缩系统及送氧系统。本文主要介绍空压机、氧压机及送氧系统的自动控制系统。一、空气压缩机的自动控制原料空气经空气压缩机压缩到5kg/cm~2左右,送往空分塔。目前空压机绝大部分采用透平式空压机。因透平空压机的P—Q特性曲线较陡,在运行过程如发生管道阻力突然增加或负荷减小的情况,空压机易发生喘振现象,影响空压机的正常运行,严重的会发生设备事
Oxygen equipment mainly includes air compression system, air separation tower system, oxygen compression system and oxygen delivery system. This article describes the air compressor, oxygen compressor and oxygen delivery system of automatic control system. First, the automatic control of air compressor Raw air compressed by the air compressor to about 5kg / cm ~ 2, sent to air separation tower. At present, the vast majority of air compressors using air compressor. Due to the steep P-Q characteristic curve of turbine air compressor, sudden increase of pipeline resistance or decrease of load in the process of operation, the air compressor is easy to surge and affect the normal operation of air compressor. Equipment occurred
