To carry out energy saving and reduction of elevator guide rails, Observation Elevators Manufacturer reminds the following energy saving technologies.

1. Improve the mechanical transmission and electric drag system. For example, the traditional worm gear reducer is changed to a planetary gear reducer or a gearless drive is used. The mechanical efficiency can be increased by 15% to 25%. The AC two-speed drag (AC-2 ) The system is changed to a variable frequency voltage regulating speed (VVVF) dragging system, and the power loss can be reduced by more than 20%.

2. The (IPC-PF series) electric energy feedback device is used to regenerate the braking electric energy to use the elevator as a vertical transportation equipment. The workload of the upward transportation and the downward transportation is approximately the same. The driving motor is usually driven by power consumption or control. Under dynamic power generation. When the elevator goes up and down under light load and gradually decelerates before the elevator is leveled, the drive motor works in the state of power generation braking. At this time, mechanical energy is converted into electrical energy. In the past, this part of electrical energy was either consumed in the windings of the motor, or it was consumed on the external energy consumption resistor. The former will cause the driving motor to generate severe heat, and the latter will need to be connected with a high-power braking resistor, which not only wastes a lot of power, but also generates a lot of heat, which will cause the room to heat up. Sometimes it is necessary to increase the cooling of the air conditioner, which further increases the energy consumption. Utilize the AC-DC-AC working principle of the inverter to convert AC power (regenerated electrical energy) generated by mechanical energy into DC power, and use an electrical energy feedback device to feed DC electrical power back to the AC power grid for use by other nearby electrical equipment to make electricity The drag system consumes the power of the power grid in a unit of time, which makes the total energy meter slower and saves energy. At present, the control technology for returning the electric energy output from the braking power generation state to the power grid is relatively mature. According to reports, the market price of electric energy feedback devices for ordinary elevators is 4,000 to 10,000 yuan, which can save more than 30% of electricity.

3. Update the elevator car lighting system. According to related information, using LED light-emitting diodes to update incandescent lamps, fluorescent lamps and other lighting fixtures commonly used in elevator cars can save about 90% of the lighting consumption, and the lamp life is 30-50 times that of conventional lamps. The power of LED lamps is generally only 1W, no heat, and can achieve various shape designs and optical effects, beautiful and generous.

4. Adopting advanced elevator control technology. Various advanced control technologies that have been matured so far, such as car unmanned automatic light-off technology, driver sleep technology, escalator frequency conversion induction start technology, group-controlled building intelligent management technology, etc. Good energy saving effect.
