Electric actuator
The electric actuator mechanism is an actuator with electricity as energy. Its main features are convenient access to energy, fast signal transmission speed, and long transmission distance; it is convenient for centralized control; the actuator remains in place during power failure, which does not affect the safety of the main equipment; high sensitivity and precision; and electric adjustment instruments Convenient coordination and simple installation and wiring. The disadvantage is that the structure is complex, the volume is large, the thrust is small, the price is expensive, and the average failure rate is higher than the pneumatic actuator. Suitable for explosion-proof requirements are not high and the lack of gas source and the use of the number is not too much.
The basic actuator is used to drive the valve to the fully open or fully closed position. The actuator used to control the valve can accurately make the valve go to any position. Although most actuators are used to switch valves, the design of today's actuators goes far beyond simple switching functions. They include position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules and PID control modules, all of which are installed in a compact housing. Because more and more factories adopt automatic control, manual operation is replaced by mechanical or automation equipment, people require the actuator to play the role of the interface between the control system and the mechanical movement of the valve, and the actuator is required to enhance the safety performance and environmental protection performance.
