电动阀门的过流限扭控制

Power-driven Valve Over-Current Limited-twist Moment Control

通过对异步电机堵转电流的研究分析,得出阀门过扭与过扭电流的对应关系。通过检测并识别定子电流方法,对电动阀门实施过扭控制。在 DFD-I型阀门电动装置中应用这种控制方法,获得满意的效果。

Being researched and analyzed the stopping-turning current in asychronous motor,we've got a corresponding connection between the over twist moment and stator current.Because of inspecting and recognizing the control method of stator current for power-driven valve in DFD- device,we've obtained a satisfied result.
