In 1990, with the rapid development of the world economy and economic globalization, developed industrialized countries have successively developed high-speed and ultra-high-speed elevators. Domestic elevator development technology is also changing with each passing day. Villa elevator is not only a walking tool, but also a symbol of human civilization. Its technological development reflects social progress and civilization.
What is the development trend of elevator technology in the future?
1. Greening From the perspective of reducing environmental pollution, the new concept of "green" will become the mainstream color of the 21st century. The global green market will launch green products in the century of enterprises, accelerate development, and provide a broad space for occupying the green marketing market. Be able to control the game.
The green concept is the general trend of elevator development. The main development trends are as follows: Continuously improve product design, produce environmentally friendly elevators with low energy consumption, low noise, no oil leakage, no water leakage, no electromagnetic interference, and no oil pollution on the shaft guide rails. The elevator traction adopts nylon synthetic fiber traction rope, steel belt and other methods, and there is no lubricating oil pollution. The installation of the elevator will not use materials that pollute the environment.
Second, there are many measures to reduce the energy consumption of villa elevators. The main reason is to make rational use of counterweights and balance, including choosing to reduce the inertia and friction resistance of the elevator mechanical system.
1. The drive system adopts a permanent magnet synchronous gearless traction machine. It can be seen from the working principle of the permanent magnet synchronous motor that its excitation is realized by permanent magnets. It does not require the stator to provide additional excitation current, so the power factor of the motor can reach a very high level (theoretically it can reach 1). At the same time, the rotor of the permanent magnet synchronous motor does not flow through the current, there is no problem of rotor loss, and its loss is generally 45% to 60% lower than that of the asynchronous motor. Since there is no low-efficiency and high-energy worm gear drive pair, energy consumption is further reduced.
2. Another energy-saving scheme is achieved through software control. After the real-time control traffic mode is established, it should be operated as little as possible to transport more passengers and minimize the number of elevator stops. The floor entrance check-in registration scheme combining elevator calls and car instructions is a revolutionary technology for the elevator control mode, which makes the passengers at the original floor station clear at a glance and maximizes the elevator efficiency of the control system.
3. Another measure to reduce energy consumption during operation is to set the acceleration and deceleration mode in the elevator operation as a variable parameter. That is, the speed, acceleration and acceleration change rate curves of the elevator control system, whether it is the change of travel distance or car load, can be simulated by simulation software to determine the optimal operation curve between different floors.
