电动执行机构是电动单元组合式仪表中的执行单元。以单相交流电源为动力,接收统一的标准直流信号,输出相应的转角位移,操纵风门、挡板等调节机构,可配用各种电动操作器完成调节系统“手动—自动”的无扰动切换,及对被调对象的远程操作,电动执行机构还设有电气限位和机械限位双重保护来完成自动调节的任务。在电力、冶金、石油化工及锅炉系统的上水及风门挡板的调节等得到广泛应用。
The electric actuator is the executive unit in the electric unit combination meter. Take single-phase AC power as power, receive a unified standard DC signal, output the corresponding corner displacement, control throttle, baffle adjustment mechanism, can be equipped with a variety of electric operator to complete the adjustment system “manual - automatic ” Disturbance switching, and remote operation of the object being adjusted, the electric actuator also has a double electrical and mechanical limit protection to complete the task of automatic adjustment. In the power, metallurgy, petrochemical and boiler systems Sheung Shui and damper damper adjustment has been widely used.
