- Environmental protection. The world is very aware of the relationship between survival and development: without environmental protection, there is no survival, and without survival, there is no development at all. The green concept has been deeply rooted in the hearts of the people all over the world, and the green concept is the general trend of elevator development. Some experts predict that “whoever launches green products first and seizes the market will have the initiative in market competition.” The development trend mainly includes: continuous improvement of product design, production of environmentally friendly low noise, low noise, no oil leakage, no water leakage, no electromagnetic elevator traction adopts synthetic fiber traction rope, steel belt and other non-lubricating traction methods. Elevator traction will use no (less) environmental materials. Elevator traction ascends and pollutes polluted elevators. Full-load downlink motor regeneration recovery power generation technology. Installing the elevator will consume the installation of scaffolding. Elevator parts have no impact on the environment during production and use (such as brake pads must not use asbestos) and the materials are recoverable.
- The drive system uses a permanent magnet synchronous gearless traction machine. Since the permanent magnet synchronous gearless traction machine has the following advantages compared with the traditional worm gear and worm drive traction machine: a) The permanent magnet synchronous gearless traction machine is directly driven, without worm gear and worm drive pair, and the permanent magnet synchronous The motor does not have a stator coil that takes up a lot of space required for an asynchronous motor, and the main material for making a permanent magnet synchronous motor is NdFeB with high energy density, high remanence induction and high coercive force, and its air gap flux density generally reaches 0.75T above, so it can be made small in size and light in weight. b) High transmission efficiency. Due to the direct drive of permanent magnet synchronous motor (without worm gear and worm transmission pair), its transmission efficiency can be increased by 20%~30%. c) Since the permanent magnet synchronous gearless traction machine does not have the noise generated by the bearing when the asynchronous motor is running at high speed and the noise generated when the worm gear pair is in contact with the transmission, the noise of the whole machine can be reduced by 5~10db(A) . d) Low energy consumption. From the working principle of permanent magnet synchronous motor, it can be known that its excitation is realized by permanent magnets.There is no need for the stator to provide additional excitation current, so the power factor of the motor can be very high (theoretically it can reach 1). At the same time, there is no current passing through the rotor of the permanent magnet synchronous motor, and there is no problem of rotor loss. Generally, the loss is 45%~60% lower than that of asynchronous motors. Because there is no low-efficiency, high-energy-consumption worm gear and worm transmission pair, the energy consumption is further reduced. e) Since the permanent magnet synchronous gearless traction machine does not have the problem of tooth profile wear and does not need regular replacement of lubricating oil, it has a long service life and basically does not require maintenance. In the near future, if the cost of producing permanent magnet synchronous motors can be solved as soon as possible, the permanent magnet synchronous gearless traction machine will replace the traction machine composed of asynchronous motors with worm and gear transmission pairs. Of course, superconducting power drag technology and magnetic levitation drive technology will also be applied to elevators in the future.
- The elevator industry will be informatized and networked. How to combine elevator control system with network technology will be the mainstream trend of elevator design in the future. In the 21st century, how to provide customers with satisfactory products and services has become a matter of life and death for every enterprise. Elevator access to the Internet can ensure that customers are provided with better and full-service services. In the future, major brand manufacturers will establish their own elevator websites (elevator-specific platforms) in the public network system in order to survive and develop. The elevator runs safely to ensure the safety of passengers. When the elevator breaks down, the elevator sends a signal to the customer service center through the network so that the maintenance personnel can timely and accurately understand the cause of the elevator failure and related information, whether the personal safety of the customer is threatened, and rush to the accident scene for repair in the first time. Emergency repairs, while comforting passengers in the elevator through the Internet, minimize the negative impact of elevator failure.It is also possible to automatically scan the components of each elevator within the specified time through the elevator network to find potential accidents and perform maintenance in advance, reducing downtime and improving the service quality of the enterprise. b) Elevator online transaction (elevator business website). Now the traditional marketing system is person-to-person sales (or face-to-face sales), and the cost of sales is high due to the need for a large number of salespeople. If the media is disseminated through the network of the elevator business website, the cost of sales can be greatly reduced. On the Internet, you can display the features, functions, shapes and dimensions of your products, as well as the required civil engineering dimensions. If you fill in the relevant data of your project online, it will automatically calculate the elevator flow, and provide N elevator configurations (including elevator model, load capacity, speed, number of stops, waiting time, running time) according to the calculation results. The user chooses. If the user needs it, you can get the quotation of each plan immediately, and you can also sign the purchase and sale contract online, and pay the purchase price through the online bank, so as to complete the purchase and sale contract.Of course, you can also download any information you think is useful online for future use when purchasing. c) Utilize the fast and accurate characteristics of the network to reduce the production cost. After China’s accession to the WTO, it is inevitable for various enterprises (especially joint ventures and foreign-funded enterprises) to purchase globally in order to reduce costs. Avoid being affected by various improper means in the procurement process, and use the elevator website to invite bids and bids to ensure that the procurement is cheap and high-quality The elevator parts, its operation is very cheap. It is also possible to network all purchased parts production plants and supporting factories that have been designated through the network. After receiving the order, the manufacturer arranges the production schedule and parts production division table through the technical department to quickly and accurately deliver the purchased parts through the network. The production plant and the supporting plant issue production instructions and indicate the delivery location (usually to reduce the round-trip freight from the production plant to the assembly plant and then to the construction site and directly deliver to the construction site), and at the same time notify the professional installation team approved by the manufacturer to enter the site to install electrical appliances through the network. (Escalator) ladder. After the installation is completed, the installation team applies online to the manufacturer and relevant government departments for acceptance. In short, many tasks from sales to installation and after-sales service can be completed through the Internet, and the cost is low, fast, accurate, and service quality is good.
- Bluetooth technology is applied in the elevator. Anyone who has installed an elevator knows that setting out and aligning wires is time-consuming, laborious, and error-prone. If the control panel and the calling system are connected through Bluetooth technology to realize wireless calling, it will be another revolution in elevator control and bring us great benefits. a) The installation period will be reduced by more than 30%. The direct benefit is to reduce the installation cost, and the customer will also reduce the cycle cost from ordering the elevator to using the elevator and increase the cash turnover rate. b) The use of Bluetooth technology on the elevator will definitely make the elevator control system use the latest and fastest microcomputers, which will further improve the reliability of the elevator machine, greatly reduce the failure rate, and further improve the control accuracy. The result is that the elevator is more efficient. Comfortable and more accurate leveling. At the same time, this also makes it possible to check the elevator status through the Internet in the future, especially the elevator maintenance in advance can be better and more comprehensive, and it will further speed up the Internet access of enterprise elevators. c) It is easier to transform the old ladder, and the time and cost will be reduced. According to the statistical table, 50,000 old elevators will enter the renovation market every year, and the use of this technology will generate huge social and corporate benefits. I believe that any enterprise will not give up this opportunity. e) It solves the compatibility and connection between elevator control and peripheral equipment well. In particular, elevators and escalators can be included in building management systems or intelligent management community systems.
- With the development of elevators to high technology, we also clearly realize that China’s per capita income is low and it is particularly sensitive to prices. Under this special environment, the market urgently needs simple and reliable popular elevators. In the future, this type of elevator will account for more than half of China’s total elevator demand. The characteristics of this type of elevator are: the configuration of the elevator meets the minimum requirements for use, but the price is very low, the failure rate is very low, the reliability is high, it is durable, basically no maintenance is required in its service life, and it is easy to use. The development direction of this type of elevator technology is mainly: a) The application of high technology and new materials in the production of elevator parts. For example, high-tech coatings are added to the surface of parts to greatly extend their service life. The elevator is controlled by the popular computer with low price and high reliability instead of the special electronic board for elevator with high price and low reliability. b) Manufacturing process improvement. Improvements in parts technology have made products less expensive and more durable. Changes in production processes and methods. Can make this kind of elevator production mode be the same as the modern large-scale automobile production mode, adopt the assembly line production mode. And the output is very high, with an annual output of 40,000 to 50,000 elevators. c) Extensive use of standard parts. Almost all parts of this type of elevator are standard parts that can be purchased in the market.
