Description
technical field [0001] The invention belongs to the technical field of electric actuators, in particular to a hot air circulation electric actuator. Background technique [0002] In the industrial control system, the electric actuator is a very important executive unit in the combined instrument of the electric unit. It is composed of the actuator body and the actuator control device. It can receive the electric control signal from the regulator and linearly Converted into mechanical angle or linear displacement, used to manipulate dampers, baffles, valves and other adjustment mechanisms to achieve automatic control. In recent years, with the rapid development of microelectronics technology and control technology, electric actuators have also achieved rapid development, but there are still some defects in the current electric actuators: because there is no hot air circulation device inside the electric actuator, the electric actuator is in the It is difficult to work normal...
