摘要
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。
Metering electromagnetic pump is simple in structure,reliable for operating and has a high cost performance,but its metering precision isn't high,It's relatively difficult to improve its performances purely by optimizing material and manufacturing and assembly technology.Based on STC12C5A60S2 micro controller unit,this paper designs metering-electromagnetic pump closed loop control system that has feedback of flux.The experiment result indicates that closed loop control system can increase metering precision of electromagnetic pump,its performance index reaches requirements of the project task.
