Before elevator maintenance, it is necessary to prepare some tools, such as wrenches, screwdrivers, wire cutters and feelers, calipers, steel tape measures, etc.
Elevator maintenance process
In the process of elevator maintenance, the first thing to be maintained is the equipment maintenance of elevator machine room. The first thing to check is the traction machine. When checking the traction machine, it is necessary to check whether the oil level in the lubricating part of the motor of the traction machine leaks oil. Then it is necessary to measure the temperature and check the gearbox and bearings of the traction machine with a thermometer.
Then what needs to be checked is the brakes. The part of the brake that needs to be checked is the gap of the brake, and the iron core and copper sleeve of the brake should be cleaned regularly. When cleaning, you can fully lubricate it with graphite powder or pencil powder.
After checking the above two items, you also need to check the speed dial and the speed limiter, which are very important. It is necessary to check whether the speed dial is firmly installed and whether the speed limiter is flexible, and it needs to be tested regularly. The elevator control cabinet also needs to be checked. If the parts inside are loose, they need to be repaired, and then the inspection of the hoistway, such as the car, the waiting hall and the car door. , all need to be checked and maintained. The belt of the door crane is the key problem to be maintained.
Elevator maintenance price
Now the maintenance price of elevators is very transparent. First of all, the maintenance price of escalators is one month in 400 yuan, and the maintenance price of passenger elevators varies according to different floors. Generally, the maintenance fee for the five-story elevator is one month in 350 yuan, while the maintenance fee for the six 6- 10/0-story elevator is one month in 450 yuan, and the maintenance fee for the ten-to fifteen-story elevator is one month in 500 yuan, if it is above the sixteenth floor.

Attention problem
Mechanical parts:
1. Elevator traction machine needs oil lubrication. There are two scales on the outer cover of the traction machine. Open the nozzle and check 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 needs to be refueled. If you don't refuel, the elevator will not be well lubricated for a long time, which will lead to the burning of the elevator traction machine and motor. After the elevator runs for a long time, the oil should be changed in time to keep the traction machine fresh and well lubricated.
2. Cleaning and lubrication of elevator car guide shoes. As we all know, the guide shoe runs on the guide rail and there is an oil cup on the guide shoe. In order to make the elevator not generate friction sound during operation, it is necessary to refuel the oil cup and clean the guide shoes regularly to clean the car.
3. Maintenance of elevator hall door and car door. Elevator faults generally occur in elevator hall doors and car doors, so attention should be paid to the maintenance of hall doors and car doors. First, refuel the upper sill of the door and keep it well lubricated, so that the elevator will not make unpleasant sounds when it is running and opening the door. Pay attention to check the switch wire of elevator safety touch panel or light curtain touch panel. Because of the high frequency of elevator door opening and closing, the switch wire will be damaged, which requires maintenance personnel to check every time they work and replace it in advance, so as not to make users doubt the quality of elevator products because of the door problem.
Electrical components:
Electrical components are roughly divided into control panel, electrical switches of various safety circuits, etc. It is the brain and central nervous system of the elevator, which dominates the start, operation and door opening and closing of the elevator, so it must be treated as the top priority in daily maintenance. It is best not to short-circuit the elevator circuit in the control panel when working. When the elevator door system fails, it is very dangerous for someone to short-circuit the elevator door for convenience, so as to find out the fault. Short-circuit doors have the most accidents.
Why? If a person opens the hall door and sticks his head in, then the elevator runs up or down right here, and the hall door is short-circuited and the elevator can't stop, then an accident is very likely to happen. Therefore, in the daily maintenance work, we must not short-circuit the safety circuit. If short circuit is necessary, it is necessary to find out which safety component is out of order and which safety component needs short circuit. After maintenance or emergency repair, the short circuit must be removed in time.
The maintenance price of elevators varies from place to place, and the charging methods for different groups of people are also different. Moreover, according to the elevator maintenance project and the specific matters in the maintenance process, there will be additional charges. The bigger the elevator, the higher the floor and the higher the charge.
