在长网多缸浆板机上,普遍采用晶闸管双闭环传动装置。其一般由6～10个分部组成,图1为8个分部使用KGS_F~A系列晶闸管双闭环传动装置的系统图。现就实际调试中会遇到的难点谈谈看法,以引起同行的兴趣。 1.部件调试 (1)速度调节器ST 由线性集成电路FC54D(或FC52)与RC反馈网络组成PI调节器,其作用是使速度大闭环获得最佳化,并限制了系统截止电流,电路如图2所示(图中符号按产品图)。 In the long net multi-cylinder pulp machine, the commonly used thyristor double closed-loop transmission. It is generally composed of 6 to 10 divisions, Figure 1 is a system diagram of eight divisions using KGS_F ~ A series thyristor double closed-loop actuators. Now on the difficulties encountered in the actual debugging talk about the views to arouse peer interest. 1. Component Debugging (1) Speed ​​Regulator ST consists of a linear integrated circuit FC54D (or FC52) and RC feedback network composed PI regulator, its role is to speed up the closed-loop to optimize and limit the system off-current, such as the circuit Figure 2 (Figure symbols by product).
