The damper actuator is a type of actuator. The actuator is a combination of an actuator and a control valve in an automatic control system. Its role in the automatic control system is to receive signals from a regulator or computer (DCS, PLC, etc.), and to adjust the flow of the process medium with its position and characteristics in the process pipeline, so as to keep the controlled automatic instrument within the required range of the production process.
The actuator is also an indispensable and important component of the automatic control system. Its role is to receive the control signal sent by the controller, change the size of the controlled medium, and thus maintain the controlled variable within the required value or within a certain range.
According to its energy form, the actuator can be divided into three categories: pneumatic, hydraulic, and electric. Pneumatic actuators use compressed air as energy. Its characteristics are simple structure, reliable and stable operation, large output thrust, easy maintenance, fire and explosion protection, and low price. Therefore, it is widely used in chemical, papermaking, oil refining and other production processes. It can be easily used with passive instruments.
Even when using electric instruments or computer control, pneumatic actuators can still be used as long as the electrical signal is converted into a standard air pressure signal of 20-100kPa through an electric-to-pneumatic converter or an electric-to-pneumatic valve positioner. Electric actuators have convenient energy access and rapid signal transmission, but they have complex structures and poor explosion-proof performance.
Hydraulic actuators are basically not used in production processes such as chemical and oil refining. They are characterized by large output thrust.
In process control systems, actuators consist of two parts: actuators and automatic adjustment mechanisms. The automatic adjustment mechanism directly changes the parameters of the production process through the actuators so that the production process meets the predetermined requirements. The actuator receives the control signal from the controller and converts it into the output of the drive adjustment mechanism (such as angular displacement or linear displacement output). It also uses appropriate actuators, but the requirements are different from those of the adjustment mechanism. The actuator is directly installed at the production site, and sometimes the working conditions are harsh. Whether it can maintain normal operation directly affects the safety and reliability of the automatic adjustment system.
A device in the automation control technology tool that receives the control signal and exerts control operation on the controlled object. Actuators are divided into three categories according to the driving energy used: pneumatic, electric and hydraulic actuators.
