Currently, the world's fastest Screw Elevator is located at the Shanghai World Financial Center. It runs at 3,600 feet per minute, and you are barely uncomfortable throughout the run due to rapid decompression. Future elevators, like airplanes, will also be equipped with pressure chambers. This will allow the elevator how fast it will be.
But the decline is another matter: it is said that despite the pressure chamber, the elevator is not allowed to drop at a speed of more than 2,000 feet per minute without damaging people's hearing.
Screw Elevator working principle
By using the principle of screw drive, the nut is rotated by the motor through the reducer (or belt), so that the nut moves up and down along the screw, thereby realizing the lifting and lowering of the manned platform.
The safety factor of taking the Screw Elevator is high. There is always something to hold underneath, that is, the power is lost, the free fall falls, the screw also drives the motor to do a large negative work, and the drop will be very slow, so the elevator will not fall. And as long as the screw is locked to prevent the free fall, the Screw Elevator is known as the "home elevator that never falls."
In the future, the speed of screw-type home elevators will be faster and faster?
Many people can consult the screw-type home elevators, but it is OK.
According to the standard of household elevator manufacturing, the current European standard for household elevators is 0.15m/s, and the national regulations for traditional domestic traction elevators cannot exceed 0.4m/s.
Regarding the speed increase of the screw elevator, the first does not meet the European elevator standard; secondly, the home use does not recommend the speed too fast; third, the speed increases, the friction coefficient of the screw and the nut is serious, and the service life of the elevator is shortened.
