摘　　要：为了研究工况切换过程中工艺系统的瞬态流动分析方法,首先对比研究了一维Flowmaster仿真、一维Flowmaster和三维CFD耦合仿真两种仿真方法,结果表明采用一维Flowmaster仿真即可满足工程应用的精度要求;然后基于一维Flowmaster仿真方法,研究了泵的转速调节控制方法,对比分析了PID控制变速方法和预设变速方法,结果表明预设变速方法可以避免泵转速的频繁调节,能更好地将流量维持在设计值。该研究结果可为变速泵驱动的工艺系统运行控制设计提供依据。In order to study the transient flow analysis method of the process system,1D Flowmaster and 3D CFD coupling simulation method are comparatively studied,which verifies that 1D Flowmaster simulation method can meet the precision requirement of engineering application.After that,control scheme of pump speed regulation is studied based on the 1D Flowmaster simulation method,comparative analysis of PID control scheme and preset scheme are conducted,which shows that the preset scheme can avoid frequent adjustment of the pump speed,and can better to maintain the system flow value to the design value.The research results can provide the basis for the design of the operation control and the process system driven by variable speed pump.
