重介质煤浆密度是选煤过程中一个重要的参数和控制指标。针对重介选煤过程设计了一种差压式密度计,介绍了密度计的设计原理、一次仪表的选择及二次仪表的硬件设计,并给出了程序流程图、经验化的温度补偿公式及仪表的标定方法。
HM slurry density is an important parameter and control index in coal preparation process. A kind of differential pressure densimeter was designed for the HM process. The design principle of the densimeter, the selection of the first time instrument and the hardware design of the second time instrument were introduced. The flow chart of the program, the empirical temperature compensation formula And instrument calibration method.
