The elevator is a special type of vehicle that consists of cumbersome safety electrical circuits and mechanical components. Strengthening the safety inspection and supervision of elevators to prevent accidents. The State Council promulgated the Regulations on Safety Supervision of Special Equipment in 2003, which clearly stipulates that the installation and maintenance of elevators are installed or maintained by elevator manufacturers or commissioned by installation units with qualifications for installation.

The elevator should be routinely maintained by the manufacturer or professional company.

1. The elevator consists of two major parts: machinery and electrical appliances. If the elevator is not maintained on a daily basis, the safety of the elevator will not be guaranteed. If the elevator needs to be refueled without refueling, the mechanical parts of the elevator will be worn and damaged, and the service life of the elevator will be greatly shortened, and the elevator cannot be used normally.

2. In the process of using the elevator, some elevator users have to find temporary workers or unqualified companies to do elevator maintenance in order to reduce costs and save money. Once the safety problem arises, even the responsible unit can not find it. If it is maintained by an elevator manufacturer or a qualified professional company, on the one hand, the maintenance technology and quality are guaranteed, and on the other hand, if there is a problem, someone is responsible.

What problems should be paid attention to in the daily maintenance of elevators?

Mechanical components:

1. The traction machine of the elevator requires lubrication of the oil. There are two scales on the outer cover of the traction machine. Open the nozzle to see that the oil should be in the middle of the two scales. If the oil is lower than the lower scale, it means that the traction machine should be refueled. If it is not refueled, the elevator will run for a long time. There will be no good lubrication, resulting in the burning of the elevator traction machine and the electric motor. After the elevator has been running for a long time, the oil should be replaced in time to keep the traction machine fresh and well lubricated.

2. Cleaning and lubrication of elevator car guide shoes. Everyone knows that the guide shoe runs on the guide rail. There is an oil cup on the guide shoe. To make the elevator not produce friction during operation, it is necessary to regularly oil the oil cup and clean the guide shoe, and clean the car.

3. Maintenance of elevator hall doors and car doors. The elevator is generally faulty on the elevator hall door and the car door, so pay attention to the maintenance on the hall door and the car door. First, the fueling place on the upper shelf of the door is refueled and kept well lubricated, and the elevator will not make an unpleasant sound during operation and opening of the door. Pay attention to the safety touch panel of the elevator or the inspection of the light curtain type touch panel switch line. Because the frequency of the elevator switch door is high, the switch line will be damaged. This requires the maintenance personnel to check in every work. It is necessary to change in advance, and do not let the user have doubts about the quality of the elevator product due to the problem of the door.

Electrical components:

Electrical components are roughly divided into control panels, electrical switches of various safety circuits, etc. It is the brain of the elevator and the central nervous system of the elevator. The start, operation and door switches of the elevator are dominated by it, so it must be in the daily maintenance work. Treat it as a middle priority. It is best not to short the elevator circuit in the control panel during work. When the elevator door system fails, some people short the elevator door for the convenience of the map, in order to find the fault, which is very dangerous, and the short-circuit door has the most accidents. why? If a person opens the hall door and extends his head inside, the elevator will just run up or down here, and the hall door can not be stopped by shorting the elevator, so the accident is very likely to happen. Therefore, we should not short the safety loop in daily maintenance work. If it is necessary to short-circuit, it is necessary to find out which safety component has a problem, which safety component needs to be shorted, and maintenance or emergency repair. After that, be sure to remove the short wiring in time.
