The selection and configuration of new elevators should be compared and selected according to the full cost of the entire life cycle of the elevator. Not only the manufacturer of the elevator, the initial purchase and installation costs, but also the energy loss and common spare parts of the later operation must be fully considered. The price and ease of replacement, maintenance and maintenance costs. The elevator operation management department should comprehensively consider the selection and configuration of the elevator in terms of energy consumption, daily maintenance and management costs, the frequency of elevator failures, and the owner's riding comfort based on the management experience accumulated on the site.
The biggest part of the elevator operation cost is the electricity expenditure of the elevator, and its power consumption is concentrated in the elevator traction machine. At present, most of the traction machines in the elevator in use on the market adopt turbine and worm deceleration and force boosting mechanisms. This kind of elevator traction The efficiency of the machine is only 74%-78%. In recent years, with the continuous development of elevator manufacturing technology, gearless permanent magnet synchronous elevators have become the mainstream products of energy-saving elevators. Gearless permanent magnet synchronous elevators are not only small in size, low in noise, and long in life. , The most important thing is its low power consumption, which can greatly reduce the electricity cost of the elevator management department. Most of the gearless permanent magnet synchronous elevators popularized in the market now use high-flux-density permanent magnet materials. The traction sheave is directly mounted on the rotor of the motor for direct transmission. There is basically no transmission loss and much power consumption. It is smaller than a geared traction machine, and its installation method can be installed in a machine roomless or small machine room. Compared with traditional turbo elevators, it can save energy by about 30%, reduce noise by about 10%, and reduce civil installation costs by about 10%.
With the application of modern new elevator control technology, the application of elevators in terms of energy saving has been highly valued by elevator management departments at all levels, and its role has become increasingly apparent. The modern control technology applied in the elevator is like the "neuron" of the human brain. It automatically adjusts the operation mode of the elevator according to the operation of the elevator and the passengers' riding conditions, and automatically generates a power-saving operation mode. The "neurons" in the new elevator control technology can control multiple elevators at the same time to form multiple elevator linkages. According to the passengers' riding conditions, the nearest elevator is controlled to reach the appropriate position at the appropriate time, which is convenient for passengers and reduces the number of elevators. The number of starts and runs, when no one is riding, the "neuron" will automatically control the elevator lighting to turn off. The new elevator control technology can also use roof solar energy as supplementary energy, which can save energy as much as 30% for multiple elevators.
