本文通过实验提出在大型泵站的现场条件下,在泵进口锥管两端取压差测量泵流量的方法。选用高精度差压变送器将压差变为电信号供计算机数据采集及处理,对测量结果进行误差分析得出的测流精度可以达到2％以内。为锥管压差测流系统提供了一种大型泵站泵流量的监测方案。
In this paper, experiments were made in the large pump station site conditions, at both ends of the pump inlet cone differential pressure measurement pump flow measurement method. The choice of high-precision differential pressure transmitter will be changed into electrical signals for computer data collection and processing, the error of the measurement results obtained by the accuracy of flow measurement can be achieved within 2%. For the cone pressure differential flow measurement system provides a large pumping station pump monitoring program.
