Selection method of rolling shutter door

Time of issue:2021-06-22

(Summary description)The rolling shutter door is a door with multi joint movable door pieces connected in series and rotating up and down with the roller above the door as the center in a fixed slide. The rolling shutter door plays the same role as the wall. It is composed of 13 parts, such as curtain plate, base plate, guide rail, support, reel, box, control box, door rolling machine, limiter, door lintel, manual quick release switch device, button switch and safety device. It is generally installed in the parts inconvenient to be separated by the wall. It is suitable for commercial facade, garage, shopping mall, hospital, factory and mining enterprises and other public places or houses. Especially where the door opening is large and it is inconvenient to install the ground door body, it plays a convenient and fast opening role. For example, it is used for garage doors, fire shutter doors of shopping malls, aircraft hangar doors, etc. Classification According to the opening form, it is divided into: 1. Manual rolling shutter. With the help of the torsion spring on the central shaft of the roller shutter to balance the force, the purpose of manually pulling the roller shutter is achieved. 2. Electric roller shutter. Use the special motor to drive the central shaft of the roller shutter to rotate to reach the roller shutter switch. When it rotates to the upper and lower limit set by the motor, it will automatically stop. Special motors for rolling shutter doors include: external rolling shutter machine, Australian rolling shutter machine, tubular rolling shutter machine, fireproof rolling shutter machine, inorganic double curtain rolling shutter machine, fast rolling shutter machine, etc. It is divided into: Inorganic cloth rolling shutter door, grid rolling shutter door, aluminum alloy rolling shutter door, crystal rolling shutter door, stainless steel rolling shutter door, color steel rolling shutter door, European thermal insulation door, galvanized steel rolling shutter door According to the installation form: In the wall and on the wall side (or inside and outside the tunnel). According to the opening direction: Roll up and side roll. It can be divided into: Ordinary rolling shutter door, windproof rolling shutter door, fireproof rolling shutter door, fast rolling shutter door, electric Australian (silent) rolling shutter door It is a misunderstanding that we must choose a thick rolling shutter door to make the door. It is not the case. We should install the opening size of our own door, the opening mode, economic conditions and use purpose. We should comprehensively consider all aspects to select a suitable material and appropriate starting method to make a rolling shutter door with long service life and low failure rate, It is not that the thicker the material, the better the rolling shutter door. How to choose a suitable rolling shutter door for yourself and the unit should comply with the mechanical principle. The higher the rolling shutter door product is, the weaker the ability to resist the sun and rain, and the shorter the service life, which is an indisputable fact. As most rolling shutter doors are exposed outdoors, they will gradually age, deteriorate and increase the failure rate due to long-term exposure to sunlight, wind and rain. The higher the roller shutter door, the larger the stress area and the worse the wind resistance. As the saying goes, "a big tree catches the wind", only by reducing the height of the rolling shutter door as far as possible and moving the overall center of gravity of the door body down, can we reduce the stress area and enhance the sense of stability, so as to effectively resist the attack of typhoon. Reducing the height of the rolling shutter door is equal to increasing the strength of the material. You should choose the right rolling shutter door instead of the expensive one. There are several key points to remember. If the larger door has no special requirements, such as fire prevention, try to choose the lighter material, such as aluminum alloy and hollow aluminum alloy. If you want to make the door larger, choose the heavier material and the motor load smaller, The service life will be greatly reduced. The bigger and heavier the door, the greater the wear is every day. In addition, we remind you that for a larger rolling shutter door, you should pay attention to pre rolling, that is, the door and shaft are generally fixed by screws. If there is no pre rolling, the screws bear more force. Relatively speaking, it is dangerous. If there is pre rolling, the door body wraps the fixing screws, so the door and shaft are integrated, which is more safe and reliable. We should pay attention to this when installing the door. In addition, when selecting the motor, do not calculate the weight of the door and the load weight of the motor properly, and there must be allowance, which is also a necessary way to prolong the service life and reduce faults.

Two types of sensors for automatic doors

2021-06-10

Automatic doors have indeed brought a lot of convenience to our modern life, and the scope of application has become very wide. Some families with good economic conditions have even installed automatic doors in their own villas. However, there will be sensors in the automatic door, which is also a very important part of the automatic door. The sensors in the automatic door are just like our eyes. With the automatic door sensor, the automatic door will know whether someone is close to him and whether he needs to open and close the door. There are two types of sensors for automatic doors. One is microwave induction and the other is infrared induction. First, introduce the first kind of microwave induction: this kind of induction is also called microwave radar, which reflects the movement of objects. This kind of sensor reflects quickly, and its biggest feature is that, for example, once someone is near the door but suddenly stops moving, the automatic door will not open. The second kind of infrared sensor: the reflection ability of this sensor is slower than that of microwave, and the others are similar. If the two sensors are combined and placed on an automatic door, the price of this automatic door product is also very expensive, and almost one of them is selected in the market.

Application characteristics of automatic induction door

2021-06-10

With the combination of scientific and Technological Development and residents' daily life, various new intelligent products have brought us convenience. The emergence of automatic door is an example. At present, automatic induction door is common in major hotels and hotels. When someone approaches the automatic door, he will realize the whole process of automatic opening and closing. There are many kinds of automatic induction doors, which are mainly made of special glass materials. The automatic induction door has a strong sound insulation effect and can also provide a quiet space in the room. The automatic induction door can be opened and closed in time, especially to resist the surrounding dust pollution; Moreover, the automatic induction door is high-end and high-grade to beautify the decoration environment. The automatic induction door can connect the alarm system with the indoor environment and intelligently warn of illegal intrusion; After the fire prevention device is installed, the fire accident can be notified as soon as possible. With the continuous maturity of the current automatic induction door technology, people can well prevent being hit when passing through the door. I believe that with the continuous development of science and technology, the functions of automatic door products in the future will be more diverse and intelligent, and the needs of consumers can be better met.
