摘要
分析现场混装炸药车硝酸铵输送计量控制方法,找出硝酸铵计量不准确的原因是计量脉冲数量不足和硝酸铵料箱内料位变化。采用测速齿轮提高计量脉冲,根据试验数据建立料位高度补偿修正函数,改进计量控制程序等方法,提高了硝酸铵的计量精度,改善了现场混装炸药的生产质量和计量水平。
Through analyzing the method of controlling ammonium nitrate transportation metering in on-site mixed explosive vehicle, the cause of inaccurate ammonium nitrate metering was found out, that was shortage of metering pulse quantity and level variation of ammonium nitrate tank. The speed gear was applied to increase the metering pulse, the level compensation function was established according to test data, and metering control program was improved, so as to enhance the metering precision of ammonium nitrate and improve quality and metering level of on-site mixed explosive.
