如何提高電動執行器的環境適應性

How to improve the environmental adaptability of electric actuators

工業操作控制機構閥門電動執行器由于工作環境比較惡劣，大多是在一些高溫、高壓、強腐蝕、高粘度、高壓差等嚴峻工況條件下。因此它也是生產控制系統薄弱環節。

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.

如果閥門電動執行器質量不過關或操作不當，往往導致自動化控制系統調節質量下降、定位不準等問題。更好保證電動執行器在高溫或低溫環境以及強輻射強磁等復雜環境中能夠正常工作，是未來電動閥門控制裝置研究發展方向。

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.

針對這方面的問題，中英合資天蝶閥門的電動執行器技術人員采用將電動閥門傳感器與智能定位器模塊進行分離安裝，在一定程度上起到了穩定電動執行機構工作狀態的作用。可以有效改善環境下閥門執行器裝置器的正常工作，也解決智能定位器模塊高損耗問題。所以作為衡量電動執行器性能關鍵指標之一，提高在特殊環境的適應能力也是相當重要的。

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.
