几种国产电动执行机构适于DCS控制的改造建议

A Reconstruction Suggestion on Several Homemade Motor-driven Actuators for its Adaption to DCS

通过对几种国产电动执行机构的分析研究 ,提出了一种对 DKJ( ZKJ)、 DKZ ( ZKZ)、 ZKD等系列执行机构的改造方案 ,经改造使执行机构实现机—电一体化 ,从而适应 DCS控制的要求 。

Based on the analysis and research on several homemade actuators.a revision scheme for the DKJ(ZKJ),DKZ(ZKZ) and ZKD series actuators is presented in this paper.After reconstruction,not only the integration of mechanic and electric is realized,but also the control demands for DCS adapted.Moreover both soft hand and hard hand standby operators are obtained.
