What are the elevator technical terms

(1) Power supply system: a device that provides power for the elevator.

(2) Traction motor: namely, the power source of the elevator. Ac elevator with AC motor, DC elevator with DC motor.

(3) Operating system: the device to control the operation of the elevator, the button control panel in the car and the call button outside the hall.

(4) Position display device: that is, the indicator light in the car and hall door can display the floor where the elevator is and the arrow can show the running direction of the elevator.

(5) mechanical layer selector: located in the machine room. Usually CONNECTED WITH THE ELEVATOR CAR WITH STEEL belt, THE mechanical - electrical device that simulates the running state of the elevator, can indicate the position of the car, select the floor, determine the running direction, send out the speed limit signal and so on.

(6) Speed limiting device: installed in the machine room. When the speed of the elevator exceeds the allowable value, mechanical kinetic energy can be generated, cutting off the control circuit and forcing the safety clamp to act.

(7) Safety clamp: when the speed of the elevator exceeds the allowable value, after the speed limit action, the safety clamp is controlled by the speed limit, and the car will be forced to stop on the guide rail. The safety clamps are on the lower sides of the car.

Buffer (8) : when capsules or heavy Dun bottom, can absorb energy, security to stop.

(9) Counterweight: It is composed of counterweight frame and counterweight block, whose weight is proportional to the carrying weight of the car. It is installed in the well and runs in the opposite direction to the car through the traction wire rope.

(10) Floor station: the place where the elevator stops on each floor of the building.

(11) Base station: the floor station where the car stops when it is running without command. Under normal circumstances, this floor station in and out of the car the largest number of people.

(12) Terminal station on the top floor: the Z-height stop of the elevator.

(13) Bottom end station: Z low stop of the elevator. When a building has an underground floor, the ground floor terminal is often not the first floor of the building.

(14) Door bar: door bar and door slider is the auxiliary guide component of the door, with the door guide and door pulley, the upper and lower ends of the door are guided and limited. When the door is in operation, the slider slides along the ground groove.

(15) Flat floor: refers to the action that makes the floor of the car and the floor door reach the same plane when the car is close to the docking station.

(16) Floor accuracy: it refers to the error value of the floor door to the vertical direction of the floor door after the car arrives at the station.

(17) Rated deadweight: refers to the deadweight specified in the design, which is the allowable deadweight allowed by the manufacturer to ensure the normal operation of the elevator.

(18) Rated speed: it refers to the running speed of the elevator stipulated by the design and the speed at which the manufacturer guarantees the normal running of the elevator. The unit symbol is M /s.
