overview

The HEM series is a new generation of multi turn electric actuators developed and manufactured by the technical team of Heli Company based on user needs and years of development experience.

The HEM series can produce various models according to user needs, such as basic type, intelligent type, bus type, intelligent split type, etc., to safely, stably, and reliably meet different application scenarios in various fields.

The HEM series multi turn electric actuator can be used not only with regulating valves, gate valves, globe valves and other straight stroke valves, but also with butterfly valves, ball valves, plug valves and other angular stroke valves after adding some rotary worm gear boxes.

The HEM series has a direct output torque range of 60N. m-800N. m and an output speed range of 18rpm-144rpm. Depending on different speeds and speed ratios, it can be combined with an electric dedicated worm gear box to convert larger and more torque requirements.

Product advantages

1. Reliability

The design of HEM series actuators has taken into account the worst-case scenarios, and all components used have undergone strict inspection and testing to ensure the long-term operational reliability of the equipment. Based on years of design and manufacturing experience in the actuator industry, each actuator undergoes layer by layer inspection before leaving the factory to ensure its long-term reliable operation under different working conditions. The new generation of actuators has an optimized control method; The enhanced signal processing method has complete shielding against interference signals mixed in the control signal; The electrical chamber is enclosed in a double sealed waterproof shell, and a handheld infrared setter can be used to set various parameters of the electric actuator. All components meet the requirements of explosion-proof level.

2. Simple debugging configuration

Debugging and software configuration are simpler and more user-friendly, with a newly designed human-machine interface, graphical menus that are easy to understand, and corresponding operating instructions that make any parameter settings more convenient. Ensuring correct parameter settings and maintaining their safety is the foundation for stable operation. The configuration interface is more diverse, providing multiple interface selection, configuration, diagnosis and other functions. It adopts high-precision dot matrix LCD, which can easily switch between Chinese and English displays. Users do not need to remember numerous identification characters, only need to follow the on-screen prompts to debug, making it convenient to adapt to different operating environments.

3. Multiple control methods

The HEM series multi turn actuator can provide various extended control functions on the basis of the original switch type and adjustment type, including Modbus RTU, Various industrial buses such as Profibus DP. Suitable for different control needs.

4. Complete self diagnosis and protection functions

It can diagnose motor overload, overheating, and power status, and automatically identify the phase of the three-phase power supply, without the occurrence of reverse misoperation due to wiring changes; In case of emergency, the actuator can remain in place or operate to a pre-set safe position; The actuator also has the ability to accurately measure the output torque and protect the valve during operation to prevent it from getting stuck; If the valve is stuck and there is no action within the preset time after the start signal is sent, the logic circuit can disconnect the motor to prevent overheating and issue an alarm signal;
