自动配比精确度关键控制技术的开发与应用

Development and Application of the Key Control Technologies for Automatic Ratio Accuracy

借鉴六西格玛统计工具,充分开发自动配料系统技术资源潜能,提炼自动配比精确度计算公式,形成了提升自动配比精确度的关键控制技术,包括出料能力提升、出料能力判定、出料能力调节和最佳水平参数控制,通过出料能力最佳水平([25±2)Hz]控制,配比精确度提升约19.337%(雨季11.169%),混匀料平均偏差减少0.03%(雨季0.016%)。

The authors referenced Six Sigma statistical tools, fully developed the technology resources potential of the automatic proportioning system, refined the computational formula of automatic ratio accuracy and formed key control technologies of promoting automatic ratio accuracy, including the promotion, determinant and adjustment of discharge capacity and optimal level parameter control. By （25±2） Hz best level control of the discharge capacity, the proportioning accuracy was improved by 19.337% about （by 11.169% in rainy season） and the average deviation of mixing materials was reduced by 0.03% （by 0.016% in rainy season）.
