基于Bently3500的风洞压缩机轴系监测系统

摘要

In order to monitor radial vibration, thrust position and key phase of compressor shafting in 0.6 m continuous transonic wind tunnel accurately, a shafting monitoring system based on Bently3500 machinery protection system was developed. By Bently3500 configuration, PLC and HMI program designing, the developed continuous online monitoring system was successfully used in wind tunnel testing and compressor commissioning. The debugging results show that: the system fully meets the requirements of compressor shafting monitoring, achieves continuous acquisition, monitoring and logic alarm of shafting working parameters, provides operation protection for compressor.%为准确监测0.6 m连续式跨声速风洞压缩机轴系的径向振动、轴向位移和键相位信号,设计基于Bently3500的轴系监测系统.采用Bently3500机械保护系统进行硬件配置和参数组态,通过PLC下位程序和上位机HMI设计,建立一套连续的在线轴系检测系统,并成功应用于压缩机运行和风洞调试.结果表明:系统能准确反映压缩机轴系的实时运行状态,实现轴系关键运行参数的连续采集、在线监测和逻辑报警,为压缩机的安全运行保护提供依据.
