为了解决现有耐火料泵排量计量方法的实时性和便捷性等问题,依据耐火料泵排量模型指出计量方法的关键是实时泵送效率系数,并分析了泵送压力—推送压力—电流三者之间的关系,在此基础之上提出基于电参量图形特征量的软测方法,对泵排量进行实时计量。方法充分利用电压、电流融合李萨如图形特征的直观性和便捷性,通过分析李萨如图形特征量,表征泵送压力的变化趋势,计算实时泵送效率,以此对耐火料泵实际排量进行实时软测量。试验表明,该方法具有较高的精度和可靠性,且易于现场非嵌入式安装和操作。
In order to solve the problem of real-time and convenience of existing refractory pump displacement measurement methods, the key point of the measurement method based on refractory pump displacement model is the real-time pumping efficiency coefficient, and the analysis of the pumping pressure-push pressure-current The relationship between the three, on the basis of this proposed on the basis of electrical parameters of the amount of graphic soft measurement method, the pump displacement real-time measurement. The method makes full use of the visualization and convenience of integrating the Lissajous figure characteristics by voltage and current, and analyzes the trend of pumping pressure by analyzing the Lissajous figure feature quantity, calculates the real-time pumping efficiency, The amount of real-time soft-sensing. Experiments show that the method has high accuracy and reliability, and easy on-site non-embedded installation and operation.
