The following steps were taken for the maintenance of the electric stretcher door:
1. Inspection of power sources and circuits: ensure that power connections are normal and check whether cables are damaged or disconnected。
2. Examination of remote controls and switches: checks whether the remote controls and switches are working and, if not, may require the replacement of batteries or the repair of switches。
3. Examination of electrical and transmission systems: checking whether the electric power is working and, if there is an abnormal sound or vibration, may require cleaning or replacing the electric power. At the same time, the transmission system was checked for loose or damaged parts that needed repair or replacement。
4. Examination of sensors and limitors: checking whether the door sensors and limitors are working and, if the sensor is unable to detect that the barrier or limitor is unable to accurately control the opening and closing of the doors, adjustments or replacement of sensors and limits may be required。
5. Cleaning and lubricants: regular cleaning of the dust and dirt on doors and orbits, and coating of appropriate quantities of lubricants to ensure the smooth operation of doors。
If the above steps do not solve the problem, it is recommended that the service provider for the maintenance of the connected electrical stretcher doors perform maintenance。
A presentation was made on the maintenance methods of the units ' electric stretcher doors。
For the maintenance of the extension door, the components of the extension door need to be understood。
Mainly include doors, electric appliances, electric control boxes, gears, tracks, taxis, airbags, door doors, etc。
These components need to be inspected and maintained during maintenance。
Second, if the extension door is not properly open or closed, it is necessary to check whether the power supply is normal, whether the electrical control box is damaged, whether the doors and the guidance tracks are resistant, etc。
In the case of electrical failure, it is necessary to check whether the circuits of the electrics, the fixeds, the capacitors of the electrics are damaged, etc。
In the case of transmission gear failure, it is necessary to check whether the gears of the gears are worn and the bearings of the gears are damaged。
In the case of a malfunction, it is necessary to check whether the link bolt of the track is loose and whether the surface of the track is clearly worn, etc。
For the maintenance of the stretching door, some details need to be noted。
For example, when dismantling doors, care needs to be taken about the weight of the doors, avoiding damage to the doors; when replacing the gears, care needs to be taken about the placement of the gears and the inappropriate installation of the gears leads to a lack of movement; and when inspecting the electrical power, attention needs to be paid to the genetic properties of the power units and to avoiding hazards such as electric shocks。
For the maintenance of the units ' electric stretcher doors, the components of the stretcher doors need to be understood before they are inspected and maintained in the light of the failure, with some detail。
Only in this way can the normal use of the door be stretched to provide safe and accessible office space。
At the same time, regular maintenance is recommended to extend the service life of the extension doors。
