针对煤粒粉碎比较粗糙,粉碎程度不均匀的现状,采用当前较先进的ZMD31050信号调理器,AT89S51单片机以及MAX202串口电平转换器实现前混合水射流超细粉碎煤粒压力自动控制装置的电路设计,将量化误差降低到0.002%,有效控制了高压水节流阀的开启,解决了因高压储料罐压力不稳而使煤粒粉碎细度不足的难题。
Aiming at the situation that the coal particles are coarsely crushed and the degree of crushing is not uniform, the circuit design of the ultra-fine pulverized coal particle pressure automatic control device of the pre-mixed water jet is realized by the current advanced ZMD31050 signal conditioner, AT89S51 singlechip and MAX202 serial level converter , Reducing the quantization error to 0.002%, effectively controlling the opening of the high-pressure water throttle valve, and solving the problem that the fineness of the coal particles is not fine due to the unstable pressure of the high-pressure storage tank.
