Actuator in what areas?The actuator, the completion of the control action of the controlled object based on the control information from the device controller. It electrical or fluid energy into mechanical energy or other form of energy required to change the control according to the controlled state of the object or other mechanical motion state (such as temperature, pressure, etc.). It acts directly on the controlled object, can play the role of "hand" and "foot".
In machinery automation systems, actuators, depending on the input energy can be divided into electric, pneumatic and hydraulic categories. Electric actuator installation flexibility, ease of use, automatic control system is the most widely used. Pneumatic actuators simple structure, light weight, reliable and has the proof characteristics, in the medium and small power equipment and machinery, petroleum chemical industry production more automatic online applications. Hydraulic actuator power, fast and good, smooth operation, widely used in power control system.
Actuators based on the use of different occasions into pneumatic actuators, components and hydraulic actuators electric actuators.
