电动执行器-绿

◆ 概述:

电动执行器一般指电动执行机构。

对于执行机构最广泛的定义是:一种能提供直线或旋转运动的驱动装置,它利用某种驱动能源并在某种控制信号作用下工作。执行机构使用液体、气体、电力或其它能源并通过电机、气缸或其它装置将其转化成驱动作用。其基本类型有部分回转(Part-Turn)、多回转(Multi-Turn)及直行程(Linear)三种驱动方式。

◆ 优点

电动执行机构的主要优点就是高度的稳定和用户可应用的恒定的推力,最大执行器产生的推力可高达225000kgf,能达到这么大推力的只有液动执行器,但液动执行器造价要比电动高很多。


电动执行器的抗偏离能力是很好的,输出的推力或力矩基本上是恒定的,可以很好的克服介质的不平衡力,达到对工艺参数的准确控制,所以控制精度比气动执行器要高。如果配用伺服放大器,可以很容易地实现正反作用的互换,也可以轻松设定断信号阀位状态(保持/全开/全关),而故障时,一定停留在原位,这是气动执行器所作不到,气动执行器必须借助于一套组合保护系统来实现保位 。

Product application scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
