HZS系列混凝土搅拌站的电控系统多采用计算机、可编程序控制器(PLC)、配料控制仪表的形式,其电控系统如附图所示。本文对搅拌站在使用过程中常见的8种故障进行探讨。1.仪表显示不准确其表现为称重时,配料控制仪表的显示值与设定值一致,但所称材料的实际值大于或小于显示值。故障的原因可能是:称量系统受外力影响;传感器漂移误差导致称量零位或称量间距变动;传感
HZS series of concrete mixing station electronic control system to use more computer, programmable logic controller (PLC), ingredients control instrument in the form of its electronic control system as shown in the figure. This article discusses the eight kinds of common failures in the process of using the mixing plant. 1. Meter display is not accurate The performance of the weighing, the ingredients control instrument display with the same set value, but the actual value of the material said is greater than or less than the display value. The cause of the fault may be: the weighing system is affected by external forces; sensor drift error leads to weighing zero or measuring the distance variation; sensing
