One, what are the accessories for automatic doors?
Due to its ease of use, automatic doors are becoming increasingly common in public spaces. The proper functioning of automatic doors depends on their components. What are the main components of an automatic door?
1、Main Controller: It is the control center for automatic doors, issuing corresponding commands to motor or electromechanical locking systems through a large-scale integrated block with pre-programmed instructions. It also controls parameters such as door leaf opening speed and opening extent.
2、Inductive sensors: Responsible for collecting external signals, similar to human eyes. When a moving object enters its working range, it sends a pulse signal to the main controller. There are two types: microwave radar and infrared sensors.
3、Electric Motor: Provides the primary power for opening and closing doors, mainly used to control the acceleration and deceleration of the door.
4、Door Leaf Traveling Track: This system constrains the door leaf's hoisting and traveling mechanism, allowing it to move in a specific direction.
5、Door leaf suspension system with rolling mechanism: Used for suspending sliding door leaves, while also driving the door leaf to operate under the power of the motor.
6、Synchronous belt: Used to transmit the power generated by the motor, and its main function is to pull the door fan hoist system along the track.
7、Lower Guidance System: This system provides guidance and positioning for the lower part of the door leaf, preventing the door leaf from swinging forward or backward during operation.
Two. What are the commonly used materials for automatic door accessories?
The materials used for automatic door accessories can be broadly classified into three main categories: polymer materials, metal materials, and composite materials.
1、High polymer materials
The main types include plastics, rubber, and synthetic fibers. Plastics and rubber are commonly used in automatic door accessories.
2、Metal Materials
The main metal materials used in automatic door accessories include stainless steel and aluminum alloys.
3、Composite Materials
Composite materials are composed of two or more different types of materials with distinct properties, which are combined through physical or chemical methods to form new materials with enhanced properties.
Three. How to select automatic door accessories
Among various automatic door accessories, the selection of sensors is crucial, as it directly impacts the level of automation for the automatic door. Additionally, safety auxiliary devices are also important to consider when selecting.
1、Select sensors with varying sensitivities based on the specific application environment.，For example，In hotels or office buildings，Choose high-sensitivity sensors.；Within the bank、High-traffic pedestrian areas, such as shopping streets，Use sensors with lower sensitivity.。
2、When installing safety auxiliary devices, it is important to note that infrared sensors should be installed to prevent automatic doors from causing injuries.
3. Equip with a backup power supply to ensure that automatic doors continue to function properly during power outages. It is necessary to equip automatic doors with a backup power supply that operates independently.
