The IML straight trip intelligent electric actuator in the IM to be transferred smart electric actuator on the basis of additional trapezoidal nut screw, flange bracket and adjust the travel agency combination. Torque and rotational speed of the multi-turn into the linear motion of the trip and the output shaft thrust. Matching with the valve, composed of units, used in power plants, petroleum, steel, chemicals, pipelines, sewage treatment and other automatic control system, meets frequently to adjust the control, but also meet the requirements of intermittent control. Directly led to the opening and closing parts of the linear motion of the valve (control valve).
Implementation of the standard code and name of this product: Q / ZTK 01-2008 "intelligent electric implementing agencies
1, the main features of the intelligent electric actuators:
* Use of large-scale digital integrated chip, powerful, high accuracy grade.
Mechatronics design, small size and light weight.
Professional pressure sensor to measure the output shaft torque value, thereby increasing the accuracy of the torque measurement values, the error rate of ≤ 5% and can be dynamically monitor, display of torque, locked rotor can be alarm.
The displacement sensor using a Hall sensor, and pulse signal digitized processing, valve positioning accuracy of the basic error of a precision.
Implementing agencies, parameter setting, commissioning and on-site electric operation by a hand-held infrared remote control settings, no need to open the lid.
The whole Chinese character display, menu-driven operation, intuitive, easy to learn and easy to understand, easy to operate.
