What is the principle of retractable door? The working principles of the two methods are different.
The working principle of the electric retractable door is mainly to drive the driven chain to move through the motor door body. When the door body moves to a certain position, the sensor will sense and feed back to the control system, and then the control system will control the rotation speed and steering of the motor to achieve the purpose of adjusting the moving position and speed of the door body. At the same time, remote control can remotely control the opening, closing, stopping and other operations of the electric telescopic door, realizing remote control and automatic management.
At present, there are two types of electric telescopic doors: Rail-free and rail-free. Rail telescopic doors are divided into two-track telescopic doors and monorail telescopic doors, which are installed on the ground in the form of single track or double track. Trackless motors use double motors, while trackless single motors have different requirements for motors because of their different operation and straightening methods.
If auto door of the track is installed on the ground, it is a rail telescopic door. On the contrary, if there is no track, it is a rail-free telescopic door, which is the easiest way to distinguish, and the rail-free telescopic door is beautiful, maintenance is due to rail telescopic doors, which is why rail-free telescopic doors have become the mainstream whirlwind in recent years. Secondly, the product design of rail-free auto door is also very novel, the following is an introduction to their essential differences:
1. Rail telescopic door wheels generally use track wheels and angle steel wheels, which are commonly used in dual-track projects. In addition, there are currently popular single tracks, the navigation card is added to the middle part of the bottom of the retractable door to make the retractable door walk in a straight line. Trackless retractable door wheels use trackless wheels (flat wheel), which need to be straightened and corrected by robots when walking.
2. The rail telescopic door machine generally adopts a single motor, which can be identified by opening the head. The Trackless telescopic door machine generally adopts double Motors, which guide walking through geomagnetism. A robot controls the left-right click action to realize linear adjustment. Therefore, many trackless systems are based on electromagnetic induction law, full circuit Ohm law, and electromagnetic force law.
