The electric actuator is composed of a drive motor, reduction gears, screw, nut, guide sleeve, push rod, sliding seat, spring, housing, turbine, and micro-motion control switches, etc.
An electric actuator is a new type of electric executive mechanism, primarily composed of a motor, push rod, and control unit, forming a novel linear executive mechanism capable of remote and centralized control. The electric actuator performs reciprocating motion within a certain travel range, with standard travel lengths typically ranging from 100 to 400mm, including 150, 200, 250, 300, 350, and 400mm. Special travel lengths can also be customized according to different application requirements. Electric actuators can be designed with varying thrusts based on different application loads, usually reaching up to 6000N. Their unloaded operating speed ranges from 4 to 35mm/s. Driven by a 24V/12V DC permanent magnet motor, the electric actuator converts the motor's rotational motion into linear reciprocating motion to push a linkage mechanism for tasks such as switching dampers, valves, gates, and baffles. Using electric actuators as executive mechanisms not only reduces the need for air source devices and auxiliary equipment required for pneumatic executive mechanisms but also decreases the weight of the executive mechanism. Pneumatic executive mechanisms require a certain amount of air pressure throughout the control operation, although small-consumption amplifiers can be used, the cumulative gas consumption is still substantial. With electric actuator executive mechanisms, power is only needed to change the control opening, and it can be disconnected once the desired opening is achieved, making them more energy-efficient than pneumatic actuators. They are widely used in the opening and closing of dampers, valves, gates, and other mechanisms in power, chemical, metallurgical, mining, light industry, transportation, and shipbuilding sectors for tasks such as material handling and flow control. They are increasingly being used to replace manual mechanisms, hydraulic valves, and automatic transmission devices.
