Electric telescopic doors are a common wall. It has flexible telescopic, large schedule, high degree of intelligence, and high safety. It is widely used in various types of industrial and mining factories, workshops, warehouses, machine rooms, garage, etc.It is very popular in some areas that need to adopt the wall.So what do you know about the principle of electric retractable doors?Today I will bring you a strategy of electric retaining doors.
Principles of electric retractable doors
The working principle of non -rail -free electric expansion doors is based on the law of electromagnetic induction, the law of the entire circuit Ohm, and the law of electromagnetic force.When the magnetic pole rotates along the clockwise direction of the clockwise direction, the magnetic poles magnetic force line cuts the rotor guide bar, and the guide strip is induced to produce the electromotive force.The direction of the electric momentum is determined by the right hand.Because the exercise is relative, if the magnetic pole is not moved, the rotor guide strip rotates along the counterclockwise direction, then the guide bar can also feel the electromotive force.Under the influence of electromotive momentum, a current is generated in the derivative bar.This current interacts with the magnetic field of the rotor magnet pole, so that the rotor guide bar is electromagnetic (ampi), and the direction of the electromagnetic force can be determined by the left hand rule.The electromagnetic torque is generated by the electromagnetic force, and the rotor turns.In this design, the electric motivation is used to drive the opening and control of the electric telescopic doors to complete the control of the electric telescopic door.
Method of Electric Expansion Door Installation
1. Fixed door body: Put the door of the electric telescopic door into the track. The bottom of the tail is fixed with a dedicated fixed card and the expansion screw of the foot.
2. Limit switch: Limit the limit device in accordance with the setting of the door body.
3. Fixed control box: The control box can be installed in the head box, or it can be moved to the room within 10 meters away from the host.
4. Connecting lines: Put the corresponding connection in order strictly in order (strictly prohibited from wiring in the state of power). The wiring must be firm, the terminal and the terminal cannot be short -circuited, and the check of the line is correct.
How to buy electric telescopic doors?
1. Brand selection
At present, there are thousands of companies engaged in electric door production, and there are hundreds of companies that are capable of engaging in electric telescopic doors. When they are truly powerful and professional, there are few people who are professional and professional.From the development of the development data of the electric door industry in the past 10 years, Sheng Shixiang, Odennogler, Huigemen, and Liangden Industry have been a few of the product technology level, production technology, and after -sales service of the electric telescopic door industry.brand.
2. Price choice
First of all, the current price calculation method of the mainstream telescopic door manufacturers is calculated according to "how much is per meter".There are many types of products in the market of electric retractable doors. From basic configuration, standards, to high -end, to high -end, to super configuration, the price is also different from hundreds of yuan to thousands of yuan 1 meter, which is different.
In addition, the prices will be different according to whether the user is selected when the user purchases the electric telescopic door, the specifications and quantities of the accessories are different, and the price will be different.The facades of enterprises, institutions and institutions are recommended to choose luxury telescopic doors, warehouses, construction sites, and other suggestions that do not pay attention to appearance.Users should buy telescopic doors in the price range suitable for their own price interval according to their needs and purchase budgets.
3. Material selection
At present, the electric telescopic doors on the market can be roughly divided into the following categories: paint -plated iron -plated electric retaining doors, ordinary steel electric telescopic doors, ordinary stainless steel electric telescopic doors, thickened stainless steel electric telescopic doors, refined stainless steel electric telescopic doors, commonAluminum alloy electric telescopic doors, thickened aluminum alloy electric telescopic doors, refined aluminum alloy electric retractable doors, etc.
The characteristics of the electric expansion doors of different materials are different and the service life. For example, the paint -plated iron telescopic door will be dropped after a period of time.In areas where strong winds are frequent, it is easy to be scratched or bleed by the wind.
When choosing the material, consumers must first understand the restrictions on product selection in the use of electric retractable doors. It is recommended to use refined thickness profiles at the corporate gate, institutions and institutions, and other places.Using ordinary profiles, in cities with more developed coastal industries, it is recommended to buy aluminum alloy electric telescopic doors. In some typhoons, it is recommended to buy stainless steel electric telescopic doors.
4. Size selection
Because the width of different doors is different, when buying a telescopic door, you should first have your own door size.The size of different telescopic doors is different after shrinking, so the length of the length of the mainstream telescopic door is calculated according to the total length of the expansion door.
In order to ensure the perfect closure of the electric telescopic door, the general manufacturer will make the electric telescopic door slightly longer than the actual length of the door.As long as consumers purchase the real width of their door, engineers can calculate the length of the electric door based on your door.
5. After -sales service selection
At present, most of Chinas electrical equipment manufacturers have adopted the national joint insurance and quality three -pack model. Since the electric door industry is an emerging industry, there will be some of the weak manufacturers or bad businesses that are only responsible for selling the products outAs for how long your telescopic door can be used, you can only listen to the destiny.
As a large -scale electrical equipment that is not cheap, electric telescopic doors are recommended to choose brands that are responsible for installing and after -sales services for nationwide insurance, quality three packages, and manufacturers.
