摘要
基于火力发电厂大管径流量测量不准确的背景,提出在不同负荷流量下通过对小管径和大管径流量的测量,分析数据得出大管径与小管径之间流量关系,用间接方式计算出大管径流量.该方法可以提高流量测量的精确度,同时进行小管径流量测量可以提高工业生产的经济性.
In consideration of the inaccuracy large pipeline flow measurement in power plant, a new method for the liquid flow measurement in large pipelines was proposed. The method can calculate indirectly the liquid flow in large pipelines through the measurement of liquid flow in small and large pipelines at different loads respectively, and then the data analysis was carded out to derive the flow relationship between small and large pipelines. This method can improve the accuracy of flow measurement as well as the economy of the small pipelines flow measurement.
