智能型电子式变频电动执行器及其应用

Smart Electronic Frequency Conversion Electric Actuator and Its Application

针对原有电动执行器只有以低速运行,通过极强的微调才能修正微小偏差这一缺点,提出智能型电动执行器与各种阀体配合,利用数字化变频技术,改造目前采用模拟技术的电动执行器,使之具有变速运行、动态响应块,调节定位精度高、稳定性好,故障率低、使用寿命长和应用场合广泛的特点。

By using digitized frequency conversion technology, existing electric actuator with analog technology had been retrofitted. This makes the actuator feature varying speed operation, fast dynamic response, high accuracy positioning, good stability, low fault rote, long operational life and wide applicable fields.
