DKJ電動執行器在電動閥門上取到驅動的作用，作為工業化自動系統中的重要驅動裝置，必然有*的一面：安裝調試簡單，在電力，冶金，石油，化工等工業部門等到越來越廣泛的應用。今天就通過小編對閥門電動執行器的知識介紹與分類等知識，進行對電動執行器說明書系統的分析從中就可以摸索出2018年DKJ電動執行器的發展方向，抓住機遇，提升價值。
Dkj electric actuator takes the role of drive on the electric valve, as an important drive device in the industrial automation system, there must be a unique side: simple installation and adjustment, in the electric power, metallurgy, petroleum, chemical and other industrial sectors, etc. Applications. Today, through the knowledge of the introduction and classification of the electric actuator of the valve by Xiao Bian, the analysis of the electric actuator description system can help us to explore the development direction of the 2018 DKJ electric actuator, seize the opportunity, and enhance the value.

DKJ電動執行器直接安裝在生產現場，有時工作條件嚴苛。能否保持正常工作直接影響自動調節系統的安全性和可靠性。
DKJ electric actuators are installed directly on the production site, sometimes with severe work-ing conditions. The ability to maintain normal operation directly affects the safety and reliability of the automatic adjustment system.

價格低廉的單片機和新型高速微處理器將全面代替模擬電子器件為主的DKJ電動執行器的控制單元，從而實現*數字化的控制系統。應用參數調度和模型辨識自適應控制將大大提高DKJ電動閥門執行器的控制性能。相對氣動執行器、液動執行器來說，接線簡單、功能強大、使用可靠的智能型電動執行器將不斷擴大應用范圍。傳統的電動執行器一般被看作是線性系統，由放大環節和積分環節組成，但實際上，絕大多數電動執行器參數在運行期間會顯著地發生改變。
Low-cost single-chip microcomputers and new high-speed microprocessors will completely replace the control unit of DKJ electric actuators, which are mainly analog electronics, and thus realize a completely digital control system. Application parameter scheduling and model identification adaptive control will greatly improve the control performance of DKJ electric valve actuators. Relative to pneumatic actuators and hydraulic actuators, intelligent electric actuators with simple wiring, powerful functions, and reliable use will continue to expand the application range. Traditional electric actuators are generally regarded as linear systems, which consist of amplification and integration. However, in reality, most electric actuator parameters change significantly during operation.
