The solution to the out-of-control system of fast door control

　　Quick doors are used in many factories, because quick doors have many advantages such as quick opening, heat preservation, cold insulation, insect protection, wind protection, dust prevention, sound insulation, fire prevention, odor prevention, and lighting. Quick doors are generally for people to pass through or for vehicles to enter and exit, so opening and closing are so frequent that long-term use will cause some problems, such as control failure. Below, we will talk about the solution to the out-of-control system of the fast door control.

　　1. The contact point of the relay of the quick door is sticky. At this time, we need to replace the relay.

　　2. The stroke of the fast rolling door moves slightly, the switch fails or the film is deformed. If this is the case, it is necessary to replace the micro switch or the contact piece.

　　3. The loosening of the screws of the quick-release door can easily lead to the displacement of the backboard. In this case, it is only necessary to tighten the screws of the slider and reset the back plate.

　　4. The slider or nut of the quick door cannot move with the rotation of the screw. This may be the need for lubricants or other solutions.

　　5. The transmission gear of the stopper of the fast rolling door has been damaged. If this happens, the transmission gear of the stopper needs to be replaced.

　　6. The opening and closing of the quick door up and down keys are stuck. This is also very simple, just replace the button if the button is broken.
