 Ⅲ、working principle

HCQ,  HCQM series of multi-turn remote control intelligent electric device  driven by the motor, through the worm gear worm deceleration, drive the  hollow output shaft rotation. In this gear box, there is a manual/automatic switching mechanism. When  the switching handle is in the manual position, the hand wheel is  operated, and the hollow output shaft is rotated by the clutch. When  electrically operated remote-control intelligent electric device, the  manual/automatic switching mechanism automatically falls back, the  clutch and the worm gear mesh, the hollow output shaft is driven by the  three-phase motor, the torque of the shaft is controlled by the current  loop, and the bevel gear meshes on the hollow shaft. Transfer the stroke to the absolute encoder.

The  intelligent controller of the multi-turn remote control intelligent  electric device receives the standard analog current control signal or  the switch quantity control signal and compares with the position signal  of the valve position sensor, and the output shaft of the remote  control intelligent electric device is positioned corresponding to the  input signal. In  the position, the positioning control is completed, and the  interlocking control, two-wire control, or event signal can be used to  position the control system at a preset position unless the output shaft  torque value of the remote intelligent electric device is greater than  the rated torque during the operation. Value  or set the torque value, otherwise the intelligent controller of the  remote intelligent electric device will meet the requirements of the  control system, issue the correct instruction, trigger the three-phase  solid state relay or AC contactor, make the motor turn on the  three-phase power, and drive the remote control intelligence The electric device operates normally.

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

HCQL  direct-travel remote control intelligent electric device is based on  the HCQM multi-turn remote control intelligent electric device, and is  additionally composed of a trapezoidal nut screw, a flange bracket and  an adjustment stroke mechanism. Convert multi-turn torque and speed into linear motion stroke and exit thrust.

Angular-stroke  remote control intelligent electric device is based on HCQ, HCQM  multi-turn remote control intelligent electric device, and it is  composed of a combination of two-stage worm gear reducer.
