The scarcity of urban land and the improvement of building technology have resulted in more and more high-rise buildings in the city, and the consequent energy consumption of elevators is increasing, accounting for about 25% of the total electricity consumption of buildings. At present, China has become the world’s largest new elevator market. Some experts predict that the Chinese elevator market will maintain an annual growth rate of 20% in the next 10 years, and the average annual sales will exceed 50 billion US dollars. Relatively speaking, among all types of elevators currently in use in China, energy-saving elevators account for only about 10% of the total, and the market potential for environmentally friendly energy-saving elevators is huge.
Observation Elevators manufacturers share energy-saving parameters of elevator products has become an important indicator in procurement, intelligent, efficient and environmentally friendly elevator products have become the development trend of the elevator industry. In the purchase of more and more developers, elevators are no longer purely procurement of building materials. While developers pay attention to the brand and quality of elevator products themselves, the subsequent installation and maintenance capabilities of suppliers have become an important factor in the final purchase. . In response to this phenomenon, elevator companies have gradually increased investment in installation and construction schemes, staffing, and service content to meet the current procurement needs of developers and governments.
Despite the rapid development of energy-saving elevator technology in China, there are still some problems that cannot be ignored in the development of the industry. At present, the energy consumption measurement of elevators is still difficult. The energy consumption measurement of elevator products is mainly aimed at molded products. The total energy consumption of elevator products during production and the use cycle is difficult to measure, resulting in a gap between the measured data and the actual energy consumption. In the future, elevator products will focus on energy saving and consumption reduction, while comprehensively considering safety performance and humanized design to avoid losing sight of each other.

Observation Elevators Manufacturers Share Prohibition Of Flammable Carryover Into Elevators
2020年5月6日Although people often emphasize safety in elevators, elevator safety accidents also occur from time to time. The following Observation Elevators manufacturers in order to popularize elevator safety common sense, reduce elevator safety accidents, and sort out the following taboo behaviors.
1. It is forbidden to pick the door or lean on the elevator: when waiting for the elevator, it is forbidden to pick the landing door by hand. Once the door is opened, not only will the car make an emergency stop, causing passengers to be trapped in the car, affecting the normal operation of the elevator, but also likely to cause passengers to fall into the shaft or be injured. During the operation of the car, once the door is opened, the car will stop urgently, causing passengers to be trapped in the car and affecting the normal operation of the elevator. Therefore, no matter whether the elevator is running or not, it is not necessary to do any action that violates the principle of setting the elevator: picking, prying, supporting, and leaning on the elevator door are extremely dangerous.
2. Children need to be accompanied by an adult to take the elevator: because children do not have a certain judgment, weak self-care ability, do not understand the safety knowledge of taking the elevator, lively and active, easy to cause misoperation, and the self-protection ability is not strong, alone Being in a car or encountering an emergency is prone to danger. Therefore, in order to avoid unnecessary accidents, children must be accompanied by adults in order to take the elevator.
3. In the car, you should follow the rules and avoid active movements: jumping in the car, shaking left and right, will cause the elevator safety device to malfunction, causing passengers to be trapped in the car, affecting the normal operation of the elevator, and at the same time may damage elevator components.
4. Take the pet to take the elevator should pay attention: Never use a long string to lead the pet to ride, should be tight or hugged to prevent the string from being caught by the layer and the car door, causing operational safety accidents.
5. Combustible and explosive items are prohibited from entering the car: Combustible and explosive or corrosive items and other dangerous goods should not be brought into the elevator car. If an accident occurs, it may cause personal injury or damage to the equipment. Especially the spoiling of corrosive materials will bring hidden dangers to the elevator that are not easy to detect.
6. Overflowing items should not be brought in: passengers will bring running rain gear, overflowing items into the car or the cleaner will bring the water into the elevator car when cleaning the floor, it will moisten the car floor and make the passengers slip and even The water enters the shaft along the gap of the car door sill and a short circuit fault occurs in the electrical equipment.

Some older building elevators may shake when lifting, and China Passenger Elevator Factory will answer it. Is this situation safe?
Everyone knows that a building may change over time, and there may be subsidence or other minor changes. When the building undergoes some minor changes or some permissible denaturation, the elevator as a device of the building will naturally shake.
So many people have felt this shaking feeling when taking the elevator. Due to the different heights, this feeling of shaking may be different. If the building is taller, the feeling of shaking may be stronger. If the building is low, the feeling of shaking is not so strong.

In the face of equipment failure, many people will be overwhelmed and will habitually think of it as an equipment problem, but it is not necessarily true. For example, what to do if a debris elevator fails? The Observation Elevators Manufacturer will share the correct way to deal with the failure of the debris elevator.
The correct operation is required when using the equipment, which is also a way to reduce the occurrence of failures and to maintain the equipment properly. Then, for the process of using equipment, strictly enforce it, and do not violate it. When this principle is followed for a long time, even the ordinary equipment effectively extends its service life. Reducing failures is also one way to deal with equipment failures.
Regarding what to do when the equipment fails, the correct way to deal with it is to stop the operation, and then ask professional maintenance personnel, even if it is delayed, do not act without authorization, or think that with rich experience, determine that a certain part of the equipment has a problem . Then, this approach is the most undesirable. After all, it involves professional problems. Of course, it requires professional maintenance staff to solve practical problems, and it also eliminates potential safety hazards.
HUZHOU FUJI ELEVATOR CO.,LTD. Reminded What to do if the debris elevator fails, and the notified professional maintenance staff fails to arrive at the site in time, they also need to do a safety alert and fault reminder to avoid being used by unsuspecting people, but it creates more problems. This is also the correct way to deal with equipment failure.

Observation Elevators not only control the running trajectory of the elevator car and counterweight, but also a solid support for emergency stopping when the car is accidentally overspeeding. Therefore, the elevator guide rail is an important component related to the safety and running quality of the elevator.
Elevator guide rails are two or more rows of vertical or inclined rigid rails installed in the elevator shaft or between floors, ensuring that the car and counterweight device move vertically up and down, and that the escalator and moving walk steps are inclined along it Or horizontal movement to provide guidance for elevator cars, counterweights or steps;
1.Effect of the quality of the elevator guide rail blank on the machining and elevator operation
The blanks of elevator guide rails are generally made of Q235A steel. The mechanical properties and bar dimensions are based on the requirements of technical standard YB / T157-1999. Among them, the verticality and straightness of elevator guide blanks are the focus of quality control. The range will not only increase the difficulty of machining, but also affect the comfort of elevator operation.
2.The concept and classification of elevator guide blanks
Elevator rail blanks, also known as T-rail blanks, belong to hot-rolled shaped steel products, and are named after the width of the floor.
Different models of elevator guide rail blanks can be divided into different series. Currently commonly used are: T75, T78, T89, T90, T114, T127-1, T127-2, T140, etc. In addition, different products can be developed according to user needs.

For the elevator to run, the first condition must have power. After the power supply enters the control cabinet, it is divided into power supply and control power supply. The output of the power supply is controlled by the control power supply. The working conditions of the control power supply are composed of a safety circuit, a door lock circuit, and a control method (ie, maintenance / normal state-driver, fire protection). The power supply is normal and cannot run, and these three conditions cannot be established at the same time. Similarly, there are four reasons for the emergency stop during operation-the frequency conversion system regards the power source and the safety circuit as mixed, because when the frequency conversion system fails, the safety circuit is disconnected at the same time.
Below the Passenger Elevator Factory to share the most basic principles of elevators:
In the elevator leveling process, the relay type is usually divided into two levels-the first deceleration and the second deceleration. For example, when the elevator is called from the first floor to the third floor, when the car will run through the second floor to the third floor, the floor sensor on the third floor will act. The relay on the third floor is activated-the sensor is installed in the middle of the second and third floors-because there is a registration instruction on the third floor and it is forward, the control system sends a stop signal:
The first stage of deceleration begins, and the elevator is switched from fast to slow. The car continues to go up. The last one on the car roof leveling sensor first enters the floor magnetic isolation board. The control system issues a stop-ready command-the second stage of deceleration starts and the elevator enters the crawling state from the slow car. After the leveling sensor enters the magnetic isolation plate (some will delay for some distance), the control system sends an arrival signal-the elevator leveling.
This type of elevator has appeared leveling (with deceleration) or even non-stop (non-deceleration). Observe the working status and analyze it as described above. Most PLC and microcomputer elevators use the * pulse value to calculate the car position, and store the pulse value of each floor at the same time. According to the pulse value control system, one level deceleration, two level deceleration or even more deceleration signals are issued in turn. The leveling sensor only crawls the leveling state after entering the magnetic isolation plate. The crawling distance is calculated according to the set conditions or the sensor enters the leveling level.
According to the above state, it is easier to distinguish the fault location by judging at which level the elevator unevenness occurs.
There is also the problem of car position correction. As we all know, for the wrong floor fault, if the elevator is driven to the lower limit, the elevator will restore the position memory, or reset.
However, during normal operation, the elevator does not touch the lower or upper terminal, but still maintains an accurate position. Of course, it will constantly adjust the position by the leveling sensor action. However, when the leveling sensor is used to correct it, it cannot meet its precise requirements. This is why sometimes the elevator may occasionally fail to stop on certain floors.
