Electric actuators are also called electric actuators. Electric is an indispensable field driving device in industrial automation control systems. It is used to control the opening and closing of valves, dampers and other equipment (also can control its opening degree). Meter one. Electric actuators (electric actuators) are widely used in various industrial fields, such as petroleum, chemical, water treatment, electricity, building materials, smelting, pharmaceuticals, papermaking, energy, food processing, shipbuilding, building self-control, etc. (For the working principle of electric actuators, please refer to another original article by Lanpu Electronics Co., Ltd. "What is an electric actuator (electric actuator) and its working principle")

It has been 100 years since the appearance of the world's first electric actuator (electric actuator). The world's first electric actuator (electric actuator) was produced by Siemens in 1905. Siemens is still electric An important producer and developer of actuators (electric actuators), its SIPOS product series occupies a very important share in China. (Later, China's Yangzhou Electric Power Equipment Repair and Manufacturing Plant (Yangxiu) has introduced SIPOS 2 technology and localized it)

China began to develop electric actuators (electric actuators) from the end of the 1960s. At that time, it was a type of electric actuator with contacts in the Soviet Union (motor contacts and electromagnetic relays were used for motor starting and commutation) ( Electric actuator) is a template imitation.

In the real sense, the first type of electric actuator (electric actuator) developed in China was in the 1980s. Driven by China's power electronics technology, the electric actuator (electric actuator) industry has developed rapidly Several major industrial automation instrument research institutes in China combined with major industrial instrument manufacturing enterprises at the time (such as Chongqing Industrial Automation Instrument Research Institute, Shanghai Industrial Automation Instrument Research Institute, Sichuan Instrument, etc.) to develop non-contact Development, the emergence of non-contact high-power switches (such as thyristors) DKJ angle travel electric actuator and DKZ linear travel electric actuator.
