如何提高电动执行器的环境适应性

How to improve the environmental adaptability of electric actuators

工业操作控制机构阀门电动执行器由于工作环境比较恶劣，大多是在一些高温、高压、强腐蚀、高粘度、高压差等严峻工况条件下。因此它也是生产控制系统薄弱环节。

Industrial operation and control institutions of the valve electric actuators are often under harsh working conditions such as high temperature, high pressure, strong corrosion, high viscosity, high pressure difference and so on. Therefore, it is also the weakest link in the production control system.

如果阀门电动执行器质量不过关或操作不当，往往导致自动化控制系统调节质量下降、定位不准等问题。更好保证电动执行器在高温或低温环境以及强辐射强磁等复杂环境中能够正常工作，是未来电动阀门控制装置研究发展方向。

If the quality of the electric valve actuator is poor or the operation is improper, it often leads to problems such as degraded quality and inaccurate positioning of the automation control system. To better ensure that electric actuators can work normally in extremely high temperature or low temperature environment and in complex environments such as strong radiation and magnetic field is the research and development direction of future electric valve control devices.

针对这方面的问题，中英合资天蝶阀门的电动执行器技术人员采用将电动阀门传感器与智能定位器模块进行分离安装，在一定程度上起到了稳定电动执行机构工作状态的作用。可以有效改善环境下阀门执行器装置器的正常工作，也解决智能定位器模块高损耗问题。所以作为衡量电动执行器性能关键指标之一，提高在特殊环境的适应能力也是相当重要的。

In response to this problem, the electric actuator technicians used the electric valve sensor and the intelligent positioner module to separately install, which plays a role in stabilizing the working status of the electric actuator to a certain extent. It can effectively improve the normal operation of the valve actuator device in extreme environments, and also solve the problem of high loss of the intelligent positioner module. Therefore, as one of the key indicators to measure the performance of electric actuators, it is very important to improve its adaptability in special environments.
