The function effect of Henan fireproof rolling shutter door The fireproof rolling shutter door is based on the steel rolling shutter, the transmission parts are modified, equipped with fireproof electrical appliances and other equipment, so as to achieve the fireproof function: the fireproof motor is controlled by the fireproof electric cabinet, and the roller is driven by the speed change device to make the rolling shutter door open and close. In case of power failure, the manual handle on the fireproof motor can also be used to achieve manual operation. major Steel insulated fireproof window At the relative movement of the machinery, the coupling is used to replace the sprocket drive, and the friction in the track is inlaid with copper plate or nylon. Steel insulated fireproof window Manufacturer It is suitable for the use or storage of combustible gases, volatile chemicals and other high ignition materials in factories and warehouses where there is or may be an explosion of fire hazards. 1. The integrated bus is used internally, and the data transmission is reliable and fast. 2. It has the functions of phase sequence automatic detection, correction and phase loss protection. The standby power of main power supply can be switched automatically (with standby power). 3. With rich reserved interfaces, it can be linked with the fire control center. 4. All electronic learning and memory limit, no matter the upper limit or lower limit positioning will never change. 5. It adopts advanced microcomputer processor technology, which is stable and reliable, without upper limit height range 6. It has smoke and temperature sensing signal synchronization and step by step detection function. 7. The setting of operating parameters is simple, convenient and accurate. 8. It has the function of manual priority escape. In case of three-phase power or main power failure, the controller can automatically lower the roller shutter through the quick release device to close the roller shutter.

The installation of Henan fire rolling shutter door is prone to some problems. One problem is the strength of the transmission device of the fire rolling shutter door. The strength of the roller shutter shaft is also an important parameter of the roller shutter door. At present, there are many unqualified products with this strength, The structure of the roller shutter shaft that seriously affects the use of the fire shutter door mainly refers to the depth of the roller shutter shaft and the shaft heads at both ends plugged into the steel pipe and the depth of the structural shaft head plugged into the steel pipe should be about 110 of the shaft length, and there should be two flanges and enough welds. major Steel insulated fireproof window The second problem is the depth of the guide rail. If the depth of the guide rail is not enough and the structure and materials are improper, once encountering a fire, the door curtain is easy to detach from the guide rail and cannot play a role in fire prevention. Steel insulated fireproof window Manufacturer The third problem is the pre rolling of the fire rolling shutter door. The fire rolling shutter door, especially the steel fire rolling shutter door, is relatively heavy, so a circle of pre rolling will be reserved on the reel to reduce the tension of the curtain weight on the screws. Prevent a curtain from cracking.

Henan fire door development prospects 1. The fire door industry is also an emerging industry, with huge market capacity and market potential. 2. Due to the high qualification threshold of fire doors, there are not many manufacturers that can really enter the fire door industry, but also Grade C fire doors Grade C fire doors Henan fire doors. According to incomplete statistics, there are more than 1000 fire door enterprises. major Steel insulated fireproof window This does not include those family workshop type processing units. The products produced by these processing units are of different grades, with prices ranging from hundreds to thousands of yuan. 3. The market pattern in the industry has not been formed yet. There are few large enterprises and brands, and there is no leading brand. The research, development and production of fire door products have played a positive role in ensuring the safety of people's lives and property. China's fire door market started late, but developed rapidly. In recent years, some European and American enterprises have actively participated in the competition in the Chinese fire door market, especially European enterprises, which are trying to make European fire doors occupy more of the Chinese market. Steel insulated fireproof window Manufacturer In the face of competitors, we must face up to the current situation. On the one hand, we should learn from our competitors modestly, and on the other hand, we should strive to enhance our own strength. Fire door manufacturers in China are facing a huge challenge. Who can seize the opportunity in this challenge will become a winner in the market.

Analysis on the influence of fire resistance time of henan fire rolling shutter door on the coming of fire hazard in building fire protection design, ensuring safe evacuation of personnel is the primary premise of fire protection design, and the important standard of fire safety evacuation is time. major Steel insulated fireproof window China has made detailed regulations on the setting of evacuation width, evacuation distance, various fire-fighting facilities and other elements in various fire technical specifications. These are hard standards for fire design and review, but in fact, these requirements are not isolated from each other and created out of thin air. They all serve to ensure the safe evacuation of people, The setting requirements in the specification mostly come from the calculation of the fire safety evacuation time, so understanding the fire safety evacuation time is the basis and premise for the design and installation of fire rolling shutter doors. The so-called safe evacuation of Henan fire shutter door refers to the evacuation of people to a safe area before the fire develops to threaten the safety of people, that is, to make the safe evacuation time less than the time of danger, which is the benchmark of evacuation design, and all other design elements should serve this goal. The main factors that can cause danger to people in fire are high temperature, toxic smoke, building structure collapse and so on. The high temperature is mainly caused by thermal convection and radiation. When the air temperature reaches 100 ℃, ordinary people can only endure it for more than 10 minutes. When the temperature exceeds 200 ℃, people will die within 5 minutes. The harmful gases in the smoke mainly include carbon monoxide, carbon dioxide, formaldehyde, acetaldehyde, hydrogen cyanide, etc. The common carbon monoxide content in the air as long as 1%, people will lose consciousness after breathing several times, which will lead to death. At present, a large number of polyethylene, polystyrene and other building materials will produce toxic smoke after combustion. Smoke will not only cause poisoning, but also reduce the visibility of people in dense smoke due to the dimming effect of smoke. When the visibility is less than 0.5m, the moving speed of people is equivalent to the walking speed when they lose their vision. Steel insulated fireproof window Manufacturer Henan fireproof rolling shutter door usually has a fire resistance limit much higher than the time of smoke spreading and flowing, but if flammable and combustible decoration materials are used in the evacuation passageway, it may also burn rapidly.
