If this steel band elevator is compared with traditional elevator, then:
One, consider with regard to the energy consumption aspect, if with identical traction condition (load-carrying, compartment, floor) relatively, then the moon energy consumption of steel band elevator of the present invention only is about 50% of traditional backpacks formula cable wire elevator, and consider the minimum use of general elevator 30 years, and the electricity charge keep the trend increase year by year for a long time always, adopt steel band elevator of the present invention can save huge energy consumption cost than traditional elevator, especially in the higher situation of frequency of utilization, both energy consumption gaps are more.
Its two, with regard to service life the aspect consider, then:
A, conventional turbine scroll-type towing machine life-span are about 15 years, and the wheeled towing machine life-span of permanent-magnet gearless of the present invention is about 50 years, so, if adopt conventional turbine scroll-type towing machine, if the elevator length of service domestic demand in 30 years it is changed twice, simultaneously, because of the non-only driver element of elevator, also concerning the aging and life-spans of spare and accessory parts such as all the other compartments, before this i.e. greatly section's renewal, so only to expend relevant with driver element, the present invention is namely well below traditional elevator;
The life-span of B, steel band of the present invention and traditional wirerope is about respectively 20 years and 5 years (safety rate), and the steel band that only need use length to equate with the unit operation distance in the steel band elevator of the present invention, and need to use the tensile deformation that the overlength wirerope produced after operation with the supply wirerope (diameter reduce length) in the traditional elevator, such as, if with 3 floors (3 stop), the elevator applications condition of the high 3.2m in building is example, then:
Steel band of the present invention uses length to be about 2 times of story heights, and traditional wirerope is about 2.5 times of story heights;
Suppose that the every unit of steel band of the present invention and wirerope all must 3 row culture tractions, then: steel band is about 10 times of prices of wirerope material, does not contain the installing wage.
They are three years old, consider from safety performance and environmental protection aspect, at first, as previously mentioned, steel band elevator energy consumption of the present invention is well below traditional elevator, more environmental protection, and, the present invention adopts steel band as drag body, and the level of noise of generation is lower than traditional cable wire, moreover, if collapsing, traditional turbine worm formula towing machine gear namely can't move, and the wheeled towing machine of permanent-magnet gearless of the present invention still can be than slow running when magnetic disappears, and the pulling strengrth of steel band of the present invention is about more than ten times of wirerope, and so the safety performance of steel band elevator of the present invention also is far superior to traditional elevator.
Take a villa elevator with identical traction demand as example, if adopt respectively steel band elevator of the present invention and traditional Backpack type cable wire elevator (following abbreviation " traditional elevator "), then consult following table:
Annotate 1: companion ladder mainly is comprised of towing machine (motor), compartment and counterweight three parts.Counterweight is lighter than fully loaded car, and its weight difference is up to half of elevator nominal payload.When moving on the heavier direction, elevator is in the power consumption state.On the contrary, when moving under the heavier direction, gravity just drags the towing machine rotation and makes it to be in generating state, produces a large amount of electric energy.Traditional elevator can't reclaim the electric energy that towing machine produces, and can only its form with heat energy be dissipated by heating resistor, and produce a large amount of used heat.And after 30～70% collections and filtering processing of permanent-magnet synchnorous gearless dragging machine available energy regeneration frequency converter of the present invention with the elevator operation energy consumption, offer with other consumers in the electrical network and use, electricity charge saving rate is up to 70%.
