The electric actuator is used as a power source, and the electrical control portion receives the upper control system control signal, driving and controlling the motor operation, the motor drives the mechanical transmission portion, converts the rotational motion of the motor rotor into the rotational movement of the turbine worm, and drive the valve by the output shaft run. Electric Executive Mechanism Working Principle:
A new electric actuator with a direct drive motor is composed of a direct drive motor, a manual operating mechanism, and an electrical control portion.
The position sensor converts the mechanical position of the electric actuator into an electrical signal supply to the electrical gas control portion to achieve a position control; the torque sensor converts the power of the electric actuator into electrical signals to protect the valve and electricity. Electric actuator; electrical control assembly, human machine interface constitutes an electrical control portion of an electric actuator, and controls the operation of the electric actuator.
The position sensor converts the mechanical position of the electric actuator into an electrical signal supply to the electrical gas control portion to achieve a position control;
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.
Since there is a sliding terminal in the electric actuator, it is easily wear, the life is short, and there is a fixed dead zone, and it is difficult to install freely, it is difficult to implement the cover debugging.
