The working principle of passenger elevator mainly includes the following aspects:
Traction system: The traction system is the core part of the elevator, which consists of traction machine, traction wire rope, guide wheel and anti-rope wheel. The traction machine is connected to the car and counterweight through the traction wire rope, and the friction between the traction wheel and the wire rope is used to drive the elevator up and down.
Guide system: The guide system consists of guide rails, guide shoes and guide rail frames. Its main function is to limit the freedom of movement of the car and counterweight to ensure that they can only move up and down along the guide rails.
Electric traction system: The electric traction system provides power to control the speed of the elevator. It includes traction motor, power supply system, speed feedback device and motor speed control device, etc.
Electrical control system: The electrical control system is responsible for operating and controlling the operation of the elevator. It includes operating device, position display device, control panel (cabinet), leveling device and layer selector, etc.
Safety protection system: The safety protection system ensures the safe use of the elevator and prevents all accidents that endanger personal safety. It includes speed limiter, safety clamp, buffer and terminal protection device, etc.
