The Working Principle Of The Lifting Column Control System

The lifting column is mainly divided into three parts: the column part, the control system and the power system.

The power control system is mainly hydraulic, pneumatic, electromechanical, etc. The working principle of the main control system is as follows.

After years of development, the column has developed into a variety of styles. The power system is mainly the following types:

1. Air-pressure automatic lifting column: Air is used as the driving medium, and the external pneumatic power unit is used to drive the rise and fall of the column.

2. Hydraulic full-automatic lifting column. Automatic lifting column: hydraulic oil as the driving medium. There are two control methods, that is, through the external hydraulic power unit (the driving part is separated from the cylinder) or the built-in hydraulic unit power unit (the driving part is placed in the cylinder) to drive the cylinder to rise and fall.

3. Electromechanical automatic lifting: The lifting and lowering of the column is driven by the built-in motor of the column.

The working principle of the lifting column control system:

1.The main principle is that the signal input terminal (remote control/button box) sends a signal to the control system, and the RICJ control system processes the signal through the logic circuit system or the PLC programmable logic control system. According to the command, the output relay is controlled to drive the AC contactor to pull in and start the power unit motor.

2. The control system can be controlled by relay logic circuit system or PLC. In addition to the conventional operation control equipment such as button box and remote control, it can also be linked with other entrance and exit management equipment and central management platform to control equipment.

3. After the motor is started, it drives the gear The pump rotates, compresses the hydraulic oil into the hydraulic cylinder through the integrated valve, and pushes the hydraulic cylinder to expand and contract. Lifting columns are divided into high security level and civilian level according to different scenarios. Schools and other places.

The working principle of the lowering column control system The lifting column is mainly divided into three parts: the column part, the control system and the power system. The power control system is mainly hydraulic, pneumatic, electromechanical, etc.
