　　TIQ series electric actuatorsBrief description:

The IQ series actuators are a new generation of fully intelligent products produced with imported British technology, adopting non-invasive design. Integrating mechanical industry technology with microelectronics technology. This product has the characteristics of comprehensive functionality, reliable performance, small size, light weight, and easy use and maintenance. At the same time, the actuator adopts LCD liquid crystal display. Visually display the working status of the actuator in Chinese or English. Debugging is simple, operation is convenient, and various working states can be sent to the control system in any relay configuration. Widely used in industries such as petroleum, chemical, power, metallurgy, papermaking, and water treatment. The company not only provides technology and services, but also fully considers the cost of users to provide them with a high-performance and cost-effective product.

The IQ series provides a complete valve drive solution. It can adapt to all multi turn, angular stroke, and linear stroke valves that need to be controlled, providing users with high standard performance and high-quality service.

The IQ, IQM, IQL, and LQ series electric devices are the new generation of intelligent products. *The ultra large scale digital integrated chip, digital torque sensor and digital displacement sensor, fully Chinese menu operation and display, and mechatronics integrated structural design have created its * functionality, excellent performance, lightweight and beautiful appearance, simple debugging, and convenient operation. Paired with opening and closing components, it forms an execution unit and is applied in automatic control systems such as power stations, petroleum, steel, chemical, oil pipelines, and sewage treatment. It can meet the requirements of both frequent adjustment control and intermittent control. The standard code and name for this product: Q/ZTK 01-2009 "Electric Device".

1. The working principle of TIQ series electric actuators and electric actuators:

The IQ series multi turn intelligent electric actuator is driven by a single-phase or three-phase electric motor, and is reduced by a worm gear to drive the hollow output shaft to rotate. In this gearbox, there is a manual/automatic switching mechanism. When the switch handle is in the manual position, operate the handwheel and drive the hollow output shaft to rotate through the clutch.

The intelligent controller of the multi turn intelligent electric actuator receives standard analog current control signals or switch control signals, and compares them with the position signal of the valve position sensor to position the output shaft of the actuator at the corresponding position to the input signal, completing the positioning control. It can also be positioned at the pre-set position of the control system based on interlocking control, two-wire control, or event signals. Unless the output shaft torque value of the actuator exceeds the rated torque value or the set torque value during operation, the intelligent controller of the actuator will meet the requirements of the control system, issue correct instructions, trigger the solid-state relay, connect the motor to the power supply, and drive the actuator to operate normally.

The multi turn intelligent electric actuator adopts a non-invasive design, and the parameters and functions of the actuator can be modified or configured through a handheld remote control.

The IQL intelligent straight stroke electric actuator is based on the IQ multi turn intelligent electric actuator, and is combined with a trapezoidal nut screw, flange bracket, and stroke adjustment mechanism. Convert the multi turn torque and speed into linear motion stroke and shaft thrust.

2. Main features of electric actuators:

(1) Adopting large-scale digital integrated chips, with powerful functions and high precision levels.

(2) Mechatronics design, small size and light weight.

(3) By using a pressure sensor to measure the torque value of the output shaft, the accuracy of the torque measurement value has been improved, with an error rate of ≤ 5%. It can also dynamically monitor, display over torque, and alarm for locked rotor

(4) The displacement sensor adopts a Hall sensor and digitally quantifies the pulse signal, so the basic error of valve positioning accuracy is level 1 accuracy.

(5) The functions, parameter settings, debugging, and on-site electric operation of the electric device are all set through a handheld infrared remote control, without the need to open the box cover.

(6) Full Chinese and character display, menu style operation, intuitive and clear, easy to learn, understand, and operate.
