一、前言阀门定位器是普通的工业自动化仪表,在国内外设计的自控系统中大多将阀门定位器与各种执行机构配合使用。一般定位器仅能与一种型式的执行机构配合使用,而且定位器易振荡,经不起振动是多年来人们关注的问题。经多年努力,在研究、设计各方面专家的帮助及国外有关资料的启发下,最近我们生产了一种多用途定位器,元器件及原材料全部国产。经上海工业自动化仪表研究所测
First, the preamble Valve positioner is an ordinary industrial automation instruments, automatic control system designed at home and abroad most of the valve positioner and a variety of implementing agencies with the use. The general positioner can only be used with one type of actuator. Moreover, the positioner is easy to oscillate and can not stand the vibration for many years. After years of hard work, with the help of experts in various aspects of research and design as well as the relevant information from other countries, recently we have produced a multi-purpose locator, components and raw materials all made in China.
