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.

<> the regular maintenance and maintenance of elevator equipment, which can make the elevator meet and meet the standards and technical requirements of the original design and manufacturing to the greatest extent; And it can ensure the safe and reliable operation of elevator equipment, reduce the failure rate and prolong the service life of elevator equipment.

In the management of maintenance work and the application of hardware, each installation and maintenance unit should establish a complete and systematic management system and measures to ensure the quality of regular maintenance work; And continuously improve the hardware conditions, improve the efficiency, quality and user satisfaction of the maintenance work.

Establish a post responsibility system. Due to the uniqueness of the maintenance work, it is determined that it has the characteristics of large workload flexibility, the site of the maintenance work and the working time of the maintenance work are not easy to control and manage, therefore, the regular inspection, maintenance and maintenance of the corresponding maintenance ladder must be respectively responsible for the relevant personnel. In this way, it can mobilize and improve the initiative, flexibility and sense of responsibility of on-site maintenance personnel; It can also strengthen the on-site maintenance work.

At the same time, it is necessary to establish a system of regular visits to users, collection of user feedback information, and quality spot checks, supervision and management of maintenance work. After the problem is found, it should be fed back to the design and manufacturing, technology, installation and other departments in time in order to improve product quality and work; And dynamically track and deal with users' questions or complaints to improve customer satisfaction. Of course, the supervision of maintenance work is far from enough to rely on the supervision or confirmation of users.

It is necessary to take the management of regular sampling inspections by the leaders and maintenance supervisors responsible for the maintenance work, and the irregular special inspections of full-time quality inspection (acceptance) personnel. Ensure that the regular maintenance work can be carried out in strict accordance with the maintenance technical regulations, so as to effectively supervise, control and manage the regular maintenance work.

Establish a maintenance database management system. For each maintenance elevator user, user files must be established, especially for the elevator that has just been put into use, the use of the Peibu elevator and the failure of each important machine can be entered into the maintenance elevator database management system, and then classified, statistical and analyzed processing. In this way, we can find out the reasons for the high failure rate of the elevator, and then "prescribe the right medicine", continuously improve the quality of product quality and installation and maintenance work, improve the reliability of elevator equipment, and reduce the failure rate of elevators.

According to the established user profile, the use and failure of the passenger elevator, as well as the original data of maintenance work, can be accumulated. And through the statistics and analysis of these data, the factors affecting the reliability of the elevator are pretreated or replaced with wearing parts in advance; Taking proactive and preventive maintenance measures can improve the efficiency and user satisfaction of the maintenance and distribution of the town.

To really do a good job in the regular maintenance and maintenance of elevator equipment, on the one hand, we should continuously improve and improve the management and hardware; On the other hand, in terms of technology, according to the technical requirements of specific models of elevators and the specific use of elevator equipment, formulate appropriate regular cycle inspection and maintenance plans, and conscientiously implement them, so as to truly make elevator equipment through effective regular maintenance and maintenance, meet the standards and technical requirements of original design and manufacturing, and reduce the failure rate and extend the service life of elevator equipment.

Elevators are related to daily transportation, and once there is a failure, it will affect life safety. So, how to maintain the elevator? What do you need to look at when buying an elevator house? We've got you covered.

How to maintain the elevator

1. Do a good job of daily inspections.

Each elevator is equipped with safety personnel, every day will be the elevator to carry out inspections, records, once found odor, sound, safety light curtain or safety touch plate is invalid, the door opening is not smooth, etc., abnormal will be notified to the maintenance to carry out on-site inspection.

2. Technical professional maintenance companies should be routinely maintained.

Mainly including the general monthly elevator maintenance will be carried out twice a month, a quarterly maintenance inspection, and its 1-3 years once this year's maintenance, they test the focus is different, especially every 15 days need to be carried out maintenance, to take into account the daily inspection, weekly inspection, monthly inspection will be careless and ignore the area.

3. Moisturizing maintenance.

The traction galvanized wire rope is very important in the prefabricated components of the elevator, it should give the elevator a suspension device, bear all the net weight of the elevator and its staff, and the adjustment of the elevator car is also driven by the sliding friction of the traction galvanized wire rope in the wheel groove. Therefore, once the traction galvanized wire rope is damaged, it will be related to people's life and financial security, and it must be regularly inspected and moistened for maintenance.

What do you need to look at when buying an elevator house?

1. Look at the total number of elevators.

If the number of superimposed floors of the house is above 12 floors and below 18 floors, then the elevator of this building shall not be less than two; The height of the pure housing building is about 19 floors, within 33 floors, and the service project is introduced in the middle of 150 to 270 households, and the elevator shall not be less than 3, among which there must be an elevator that takes into account fire safety. Buyers need to pay attention to the introduction of the whole building and the total number of elevators, and the quality and starting speed of the elevators are also very important.

2. Look at the status of the power supply system.

Buyers must consult with the real estate developer about the status of the building's power supply, pressure, power supply system, backup power supply and other aspects. Generally, high-rise buildings have built water storage tanks on the high-rises, and the water is pumped to the middle and high-rise first, and then supplied later, so that the residents on the top floor will not be unable to use water due to insufficient work pressure; The configuration of emergency generator sets is also important to ensure that the elevator can also operate temporarily in the event of a power outage in the urban area.

3. Look at the status of property management services.

Property management services for high-rise buildings should not be ignored by home buyers, especially the supervision of security personnel countermeasures. There are many problems such as whether the ground floor of the building is set up to be on duty, whether there are security guards patrolling the corridor, and the evacuation safety of emergency personnel.

4. Look at the comfort.

Buyers should consider the comfort level after moving in, and the key is to make themselves comfortable and satisfying. Secondly, the relative density of housing and the viewing platform are crucial. What is the quality of high-rise housing, density is important, the smaller the relative density, the greater the quality of settlement; Under the premise of low density, special attention should also be paid to the garden landscape, especially when choosing high-rise or higher floors, not only should the town pay attention to the garden landscape of the house, but also take into account the overall planning of the surrounding city.
