摘　　要：在水煤浆添加剂的配剂过程中,为提高工作效率及降低人工操作引起的偏差,提出了基于液位控制和流量控制的自动配剂控制方案,介绍了两种方案的配剂系统组成、正式配剂前的初始化校验、校验结束后的配剂计算及两种配剂方案的控制过程,并根据实际应用需求提出了可行的改进方案,分析了几种方案的优缺点,并通过两种自动配剂控制方案实现“一键配剂”的效果。To improve efficiency and reduce deviation caused by manual operation in the dosing process of coal water slurry additive, two automatic dosing control schemes based on level control and flow control are proposed. The composition of the dosing system, the initial calibration before the formal dosing, the dosing calculation after the calibration, and the control process of the two dosing schemes are introduced. Realistic enhancement ideas based on the actual application requirements is offered. The benefits and drawbacks of various solutions are analyzed, and the “one-touch dosing” result is realized by two automatic dosing control schemes.
