摘要
过力矩保护是电动执行器的一个重要控制环节,它的控制精度直接决定着执行器能否对自身和连接的阀门起到保护作用。本文从三种主流过力矩保护方式的优缺点及控制精度等方面进行对比和分析,以判断过力矩保护的发展方向。
Over torque protection is an important control element of the electric actuator.The control accuracy will directly determine whether the actuator itself and the connection of valves play their protective role.This paper compares advantages and disadvantages,the precision of control and other aspects of the three mainstream over torque protection methods, so as to judge the future development of the over torque protection.
