What problems should be paid attention to in maintenance of elevators in villas
Core Tips: Mechanical Components: 1. Cleaning and Lubrication of Elevator Car Guide Boots. Everyone knows that the guide boots are running on the guide rails. There are oil cups on the guide boots. In order to make the elevator run without frictional noise, it is necessary to make regular use of them.
Mechanical components: 1. Cleaning and lubrication of elevator car guide boots. Everyone knows that the guide boots are running on the guide rails, and there are oil cups on the guide boots. In order to make the elevator run without friction, it is necessary to regularly refuel the oil cups and clean the guide boots, and to clean the car's hygiene. 2. Maintenance of elevator hall door and sedan door. Elevator failures generally occur in elevator hall doors and sedan-chair doors, so attention should be paid to the maintenance of the hall doors and sedan-chair doors. Firstly, the upper shelf of the door should be refuelled to maintain good lubrication, so that the elevator will not make unpleasant noises in operation and in the opening of the door. Attention should be paid to the inspection of elevator safety contact plate or light curtain type contact plate switch line, because the frequency of elevator switch door is high, which will damage the switch line, which requires maintenance personnel to check in every work, the change should be changed in advance, so that users do not doubt the quality of elevator products due to door problems.
3. The tractor of elevator needs oil lubrication. There are two calibrations on the outer cover of the tractor. Opening the nozzle to check the oil should be in the middle of the two calibrations. If the oil is lower than the following calibration, it means that the tractor should be refueled. If not refueled, the long-term operation of the elevator will not get good lubrication, which will lead to the burning of the tractor and motor. After the elevator runs for a long time, the oil should be replaced in time to keep the tractor refreshed and lubricated.
Electrical components: Electrical components are roughly divided into control screen, electrical switches of various safety circuits, etc. It is the elevator's brain, the central nervous system of the elevator, the elevator's start, operation and door switches are dominated by it, so it must be treated as a top priority in daily maintenance work. In the work, it is better not to make short connection of elevator circuit in the control panel. When the elevator door system fails, some people short-connect the elevator door for convenience, so as to find out the fault. This is dangerous, and the most accidents occur in the short-connect door. Why? If a person opens the hall door and stretches his head inside, the elevator runs up or down to this point, and the hall door is short-connected elevator can not stop, so the accident is very likely. Therefore, we must not short the safety circuit in our daily maintenance work. If we have to make short connection, we must find out which security components are out of order, which security components need to be short connected, and after maintenance or urgent repair, we must remove the short connection in time.
Although the number of elevators is increasing and the workload of elevator maintenance is increasing, maintenance units should do a good job in elevator maintenance, strengthen safety inspection and supervision management, prevent accidents, so as to ensure people's travel safety, which is also the glorious and sacred duty of maintenance units.
