摘要
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。
Electric Actuator is the executive unit of electric unit combination instruments in it is based on a single-phase AC power supply for power, accept standard DC signal of uniform output angle displacement, corresponding, manipulation of damper, baffle adjusting mechanism, can be matched with various electric operation complete regulation system 'disturbances witching automatically without manual', and on the regulated object remote manual operation, electric actuator is also provided electrical limit and mechanical limit double protection to complete the automaticadjust ment of the task. It is widely used in the regulation of other departments and water supply of electric power, metallurgy, damper, petrochemical and boiler system.
