What is the main work of elevator maintenance?

In fact, whether an elevator is well maintained is not only to see its brand, but also to see how well it is installed, used and later maintained and repaired. As an elevator repair and maintenance worker, how should we do our job well?

The elevators I am currently responsible for maintaining include newly installed passenger elevators that have been in use for a short time and freight elevators that have been used in the factory for many years. First of all, we must do a good job in the monthly elevator maintenance work plan, and regularly carry out comprehensive inspection and maintenance of the elevator (under the premise of ensuring safety). For example, for freight elevators that have been used for many years, we mainly check and test each safety switch to determine whether it is normal.

Check the situation of the computer room first, because the frequency of use is higher, the contactors are more prone to poor contact or aging, such as, BY(LB), U, D, DO, DC and other contactor contacts, need to use a multimeter to measure whether the contacts are in normal contact and whether the terminal pile heads are loose; Check the condition of the oil level and oil quality of the traction machine, how is its operation, whether there is abnormal noise and odor, whether the holding turn suction and release are flexible, whether the gap meets the specified standards, whether the temperature of the traction machine is normal, and how the tension and wear of the traction rope are all the work contents that we must check.

The work on the top of the car mainly includes checking whether the door lock switch of each hall and car door is in normal contact, whether the switch action is effective, and how the wear and lubrication of the car guide shoe are.

Special attention needs to be paid to the maintenance of passenger elevators and escalators, because the use of large and complex people, especially office buildings and shopping malls, should be carefully done in every detail during maintenance. In addition to the overall hygiene, it is more important to check the safety switches, especially the opening and closing contacts of the door system, the door guide shoes, etc., because most of the operation faults occur in the door system failure. The electronic board should be discharged once a month; Check the condition of emergency lights, alarm bells, and walkie-talkies to ensure that they are working effectively; Always pay attention to the elevator operating environment, for the real estate in the decoration stage, the pit should be cleaned frequently, because the elevator is easy to bring dust to all parts of the elevator during the operation, which affects the sanitation of the elevator car and hall door, such as the better environment of the real estate can be separated for a longer time.

For the elevator maintenance work in general, the work revolves around the mechanical and electrical parts, we use vision, smell, hearing, and touch to judge and inspect the elevator, and the other parts that should be adjusted and replaced need to be adjusted and replaced in time to avoid unnecessary failures and complaints; Try to meet customer requirements and listen to customer opinions, and sincerely communicate with customers.

In short, we should continue to sum up experience and lessons in practice, and revise our working methods in a timely manner, so that our work can meet the needs of customers to the greatest extent and create the greatest economic benefits for the company.

Let me tell you! First, I will teach you how to clean the elevator! Including the door head in the hoistway, the door lock contact! The pulley track of the hall car door, the car roof! Hoistway pit, machine room, control cabinet! At the same time, it will also teach you how to detect the use of elevators!

Then it's about teaching you how to fix the elevator! Including some daily breakdowns!

That's all! However, doing elevator maintenance is a job that is not productive, and the recruitment comes and goes, the working hours are not fixed, look at the face of the person, and the three meals are not fixed! I don't want to do it.

Elevator switch maintenance precautions.

1. The traction machine of the elevator needs oil lubrication.

When maintaining the elevator, if its grease nipple capacity is lower than the scale mark, lubricating oil must be added immediately. If this problem is not solved in time, the elevator will be burned due to friction, so special attention must be paid to it.

2. Cleaning and lubrication of elevator car guide shoes.

The guide shoe is operated on the elevator rail, and it also has an oil cup on it, so it must be checked for oil during maintenance, and if the oil is below the scale mark, it must be refueled in time. In addition, the guide shoes must be cleaned so that they can be easily used.

3. Maintenance of elevator hall doors and car doors.

When maintaining the elevator, the maintenance of the hall door and the car door is also a key point to pay attention to. Most of the reasons why elevators break down are because of hall doors and car doors, so we should pay attention to their maintenance. They must be kept lubricated so that they will be smoother to use.

The traction machine of the elevator needs to be lubricated with oil. There are two scales on the outer cover of the traction machine, open the grease nozzle to see that the oil should be in the middle of the two scales, if the oil is lower than the scale below, it means that the traction machine should be refueled, if you do not refuel, the elevator will not be well lubricated for a long time, which will lead to the burning of the elevator traction machine and the motor. After the elevator runs for a long time, the oil should be changed in time, so that the traction machine always keeps fresh and good lubrication.

2.Cleaning and lubrication of elevator car guide shoes.

We all know that the guide shoe runs on the guide rail, and there is an oil cup on the guide shoe, so that the elevator does not produce friction sound in operation, it is necessary to regularly refuel the oil cup and clean the guide shoe, and the hygiene of the car should be cleaned.

3.Maintenance of elevator hall doors and car doors. Elevator failures are generally mostly on the elevator hall door and car door, so attention should be paid to the maintenance of the hall door and car door.

Pay attention to the inspection of the safety touch plate of the elevator or the light curtain type of the contact plate switch line, because the frequency of the elevator door opening and closing is high, which will damage the switch line, which requires maintenance.

Dynamic disinfection is sterilization and disinfection when there are people. On many occasions, it is required to protect against microbial contamination in an all-round and whole-process manner for production, testing, and personnel on site. Sterilization, disinfection, or removal of microbial activity, is an important means of controlling microbial contamination.

Common indoor disinfection methods include physical, chemical, biological and other methods. The commonly used disinfection method of chemical agents has a certain toxicity due to the chemical agent itself.

Elevators can often be seen in daily life, and now the skyscrapers are assembled elevators, although they bring us a certain amount of convenience, but they are usually indispensable to be repaired, after all, they belong to industrial equipment, and it is not good to maintain safety production accidents. So, what are the main tasks of elevator maintenance? What are the advantages of elevators?

Next, we will take you to take a look at this correct answer and take a look at what the advantages of the elevator are.

What are the main tasks of elevator maintenance

1. Lubrication effect.

The first traction wire rope is very important in the prefabricated components of the elevator, it is the main equipment to give the elevator suspension, bearing all the net weight, and the adjustment of the elevator car is also driven by the sliding friction of the traction wire rope in the wheel groove. Therefore, once the traction wire rope is damaged, it will be related to people's life and financial safety, and it must be regularly inspected, lubricated and maintained.

2. Non-destructive testing technology.

Once the wire rope is widely used, its performance and service life will gradually begin to be damaged and reduced, so it must be carried out in accordance with the provisions of the regular inspection and real-time monitoring system, which is mainly divided into two categories: external detection and internal structure detection. External testing can supervise whether the surface is corrosion, deformation, damage and other shortcomings such as the number of broken belts exceeds the standard, and the internal structure damage can also be achieved according to new technologies such as radiographic testing, acoustic testing, mechanical testing, ultrasonic testing, eddy current flaw detection, vibration testing, etc.

3. Stainless steel wire lubrication.

The wire rope should be lubricated and cleaned on time to ensure that the application cycle is short, especially the surface of the traction wire rope will always accumulate a layer of oil stains, which is caused by the mixing of lubricating oil and dust. Stainless steel wire lubrication also has an anti-corrosion cushioning effect, which can reduce damage, etc.

4. Mechanical parts.

Elevator traction machine, elevator elevator car guide shoe, elevator hall door, elevator floor door and other mechanical parts must be maintained and cleaned up, and the plum is related to the application of the elevator.

5. Household appliances travel air components.

The elevator in the safety circuit electrical switches, control cabinets and other household appliances, residential friendly reminders are also to maintain a good job, it masters the elevator start, operation, power switch, etc., equipment maintenance is not done well is also prone to elevator door system abnormalities.

What are the advantages of elevators?

1. It is more reliable, more sensitive, and can accurately detect the internal and external shortcomings of the wire rope to ensure safety;

2. More economic development, according to quantitative testing, to prevent the regular maintenance of the wire rope caused by great consumption, to achieve rational use of resources, and to further reduce the cost of elevator maintenance;

3. Easy to operate and improve efficiency.
