If you want to learn maintenance and maintain elevators, do you have to start from installing elevat

It is necessary to start with the installation of the elevator, because the structure of each part of the elevator and the safety distance are only known after the installation process. After you can install the electrical part, it means that you have a clear understanding of the peripheral wiring of the elevator. This makes it possible to deal with some minor glitches.

When you are able to debug the elevator, it means that you are familiar with the control principle of the elevator. Only at this point can I consider it qualified.

Are you going to eat this bowl of rice in the elevator for a long time? Let's start with installation.

Maintenance and maintenance, there is no technical content at all, and the maintenance and commissioning of the technical flow, generally from the installation of learning, installation is the foundation, the basis of learning, only after the installation, in order to know what is going on with the elevator, there is a direct understanding of the future development.

As for the problem of falling, I can only say, you see that you have an accident, and you don't learn to drive? As long as you abide by the rules and be cautious, this kind of thing will not happen, and those who have accidents are serious violations of safety operating procedures.

Hello handsome guy: the idea is good, take the initiative to find a way, that is, take a big step forward in success. Congratulations..

The next thing is that you can persevere. How long has it been.

My suggestion: elevator maintenance + want to learn some technology, this is very easy, so go === The elevator is a mechatronics product, it is a combination, it is perfect. He has to complete the manned mission again, and the GB has a lot of requirements for him.

You just want to take care of the technology. It is to go to the simulated dismantling and installation of the elevator (this is not to the front line is not understandable, as for how to go, the cultivation path is different, but the destination is the same, don't be limited to the scene here, read thousands of books and walk thousands of miles, hehe). Got the ins and outs.

Next, focus on the key point, that is, the elevator control part, will not be debugged, overhauled, and maintenance fart! So you have to ask for advice to figure it out. The ancients said that it is good to capture the king first.

The key parts are grasped more, and the maintenance is naturally captured.

To learn to maintain the elevator, we must start from the installation, and installation is the foundation. After installing the elevator, I know the elevator better.

Hello, you need an elevator installation and maintenance certificate to be an elevator maintenance worker. Elevator installation and maintenance certificate application conditions: (1) over the age of 18 (including 18 years old and under the age of 60), with full civil behavior difference nuclear force.

Summary. Dear, <>

The traction wire rope is very important in the elevator components, it is a device to provide suspension for the elevator, bearing the full weight of the elevator and the passengers, and the lifting of the elevator car also depends on the friction of the traction wire rope on the wheel groove to drive. Therefore, once the traction wire rope is damaged, it will be related to the safety of human life and property, and it needs to be regularly inspected, lubricated and maintained. 2. Non-destructive testing.

Once the wire rope is used, its performance and life begin to gradually wear and tear down, so it must be regularly inspected and monitored in real time according to the regulations, which is mainly divided into two parts: external inspection and internal inspection. External inspection can monitor whether the surface has defects such as corrosion, deformation, wear and fracture exceeding the standard, and internal damage can be achieved through radiographic testing, acoustic testing, mechanical testing, ultrasonic testing, eddy current testing, vibration testing and other technologies.

What should be done for daily maintenance of elevators?

Dear, <>

The traction wire rope is very important in the elevator components, it is a device to provide suspension for the electric shelter ladder, bearing the full weight of the elevator with filial piety and passengers, and the lifting of the elevator car also relies on the friction of the traction wire rope on the wheel groove to drive. Therefore, once the traction wire rope is damaged, it will be related to the safety of human life and property, and it needs to be regularly inspected, moistened and maintained. 2. Non-destructive testing.

Once the wire rope is used, its performance and life begin to gradually wear and tear down, so it must be regularly inspected and monitored in real time according to the regulations, which is mainly divided into two parts: external inspection and internal inspection. External inspection can monitor whether the surface has defects such as corrosion, deformation, wear and fracture exceeding the standard, and internal damage can be achieved through radiographic testing, acoustic testing, mechanical testing, ultrasonic testing, eddy current testing, vibration testing and other technologies.

3. Steel wire lubrication. The wire rope needs to be lubricated and cleaned regularly to ensure a short service life, especially the surface of the traction wire rope often accumulates a layer of oil, which is caused by the mixing of lubricating oil and ash Li Songchen, if it is not removed, it will affect the service life, and will also change the friction coefficient and reduce the traction capacity. Wire lubrication also has anti-corrosion protection, which can reduce wear, etc.

4. Mechanical parts. The elevator towing inspection machine, elevator car guide shoe, elevator hall door, elevator car door and other mechanical parts also need to be maintained and cleaned, which is related to the use of the elevator. 5. Electrical parts.

The safety circuit in the elevator electrical switches, control panels and other electrical components also need to be maintained, it controls the elevator start, run, switch, etc., maintenance is not done well is easy to occur elevator door system failure.

How to maintain the elevator compensation chain?

1. The traction wheel groove and traction wire rope are clean, and the tomato is not seriously greasy, and the tension is even. 2. The speed governor wheel groove and the speed governor wire rope are clean and not seriously greasy. 3. The transmission wire rope in the finger car door system shall be cleaned and adjusted according to the requirements of the manufacturing unit.

1.The construction elevator should be frequently inspected, maintained and maintained, the transmission part should have enough lubricating oil, the wearing parts must be frequently inspected, repaired or replaced, the bolts of the machinery, especially the parts that often vibrate, such as the tower connecting bolts should be checked whether they are loose, if they are loose, they must be tightened or replaced.

2. The brakes of each mechanism should be checked and adjusted frequently to ensure that the gap between the brake pad and the brake wheel is flexible and reliable. On the friction surface, there should be no dirt, and if there is dirt, it must be washed off with gasoline or thinner.

3. The lubrication of the gearbox, gearbox, external gear and other parts and the hydraulic oil are carried out according to the requirements in the lubrication table.

4. Pay attention to check whether there are broken wires and loose strands in each part of the wire rope. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance of wire rope should be strictly in accordance with the provisions of GB5144-85.

5. All open gear transmissions must have protective covers.

6. Check the connection of each part frequently, and tighten it if it is loose. The connecting bolts of the tower body should be checked for tightness when the tower body is compressed (the method of rotating arm can be used to cause the compression state), and all connecting shafts must have cotter pins and need to be fully opened.

7. Always check whether the operation of each institution is normal, whether there is noise, and if a fault is found, it must be scheduled in time to eliminate it.

8. When installing, disassembling and adjusting the slewing mechanism, it is necessary to pay attention to ensure that the center line of the slewing mechanism reducer is parallel to the center line of the gear, and its meshing surface is not less than 70%, and the meshing clearance should be suitable.
