电磁泵结构简单、工作可靠,性价比高,但计量精度不高,单纯依靠优化材料与制造装配工艺来改善其性能有较大难度。基于STC12C5A60S2单片机研制了具有流量反馈的计量电磁泵闭环控制系统。实验结果表明,闭环控制系统能够提高电磁泵的计量精度,其性能指标达到了项目预期的要求。
The structure of the electromagnetic pump is simple, reliable, cost-effective, but the measurement accuracy is not high, relying solely on optimizing materials and manufacturing assembly process to improve its performance more difficult. Based on STC12C5A60S2 microcontroller developed with a flow feedback metering electromagnetic pump closed-loop control system. The experimental results show that the closed-loop control system can improve the measurement accuracy of the electromagnetic pump, and its performance index meets the expected requirements of the project.
