The electric actuator is an executive unit in an industrial automation system, which is widely used in pressure, temperature and flow control in electricity, chemical, petroleum, metallurgical and other industries.
The electric actuator is used in the industrial site and the valve supporting, which is an electromechanical field device. It controls and adjusts the pressure, flow, and temperature in the system by controlling the position of various valve interior cutting parts. The electric actuator is mainly composed of a motor, a mechanical transmission portion, and an electrical control portion. The mechanical transmission portion of the electric actuator structure is mainly composed of a worm wheel member, an output shaft member, a main box, a connection flange and a manual operating mechanism. .
