根据大型压缩机组的运行经验,选转子的振动量为主要监视参数,给出轴心轨迹,振动幅值,以转速为基准的谱分析等信息。作为运行监视与诊断的基本依据。文中给出以 PC 机为基础的主从式测量系统的执行策略和结构、硬件设计、软件设计的内容并提供了运行结果。 According to the operating experience of large compressors, the rotor vibration is the main monitoring parameter, and the information such as the axis locus, the vibration amplitude and the spectrum analysis based on rotation speed is given. As the basic basis for operation monitoring and diagnosis. The article gives the implementation strategy and structure of the PC-based master-slave measurement system, hardware design, software design and provides the operating results.
