多工段多工位泵试验台控制方案设计

Control Design Scheme about Multi-work Section and Multi-work Station Trial Stage of Pump

摘要:

为了准确测量、改进泵的各项水力性能并对相关试验参数进行记录，需要一个可靠运行、试验精度高的泵试验台。针对上述目标，介绍了正在建设中的多工段多工位泵试验台控制方案中四个关键点的设计方案，包括控制系统设计、抗干扰设计、主动力装置（变频器）的控制设计和数据采集设计。在这四个关键点的设计上均提出了几种可供选择的方案并最终根据项目要求和工程经验做出了选择。同时这些设计充分应用了目前比较先进的数字化传输控制技术、环网冗余技术、光纤隔离技术及其它稳定获取数据的技术，这对泵试验台的连续可靠运行和稳定可靠的获取试验数据尤为关键。这些经过仔细比较选用的方案具有很高的可靠性、获取数据的准确性和一致性、操作的简便性和良好的经济性。

Abstract:

Four key designs are introduced about control scheme of multi-work section and multi-work station trial stage of pump that is being constructed, the four key designs include control system design、anti-jamming design、control design about main drive device(transducer) and data acquirement design. Several possible selections are provided and decision is made finally in the every key design. These designs that are compared and selected carefully possess advantage of high reliability、veracity and coherence of data acquirement、operation convenience and low invest cost.
