A brief talk on the problems encountered in the fire acceptance of Henan fire rolling shutter door 1. The curtain plate coating falls off and rusts, and the curtain plate has obvious pressure pits, concave convex, and penetrating holes. high quality Class A fireproof window The rolling shutter is a complete fire protection product. If the shutter has problems, it will directly affect the fire resistance limit index of the rolling shutter. 2. The guide rail is deformed and the curtain board is stuck or falls unevenly. The fireproof rolling shutter door generally moves along the guide rail. If the guide rail is twisted or broken, the rolling shutter door will not be able to move to the specified position, which will not achieve the effect of fire separation. 3. On the roller shutter, the lower limit fails or the limit line is wrongly connected. Class A fireproof window direct deal This often happens on the fire roller shutter of the atrium. Because the fire roller shutter of the atrium is sometimes installed outside the walkway of the upper floor, there is no floor under the roller shutter to close it, and a large gap is leaked, so the fire separation of the upper and lower floors cannot be reached.
What is the standard of Henan refuge door? Requirements for fire protection structure: 1) The floor of the evacuation floor must be cast-in-place reinforced concrete floor, and the fire resistance must be 2.00h or higher. high quality Class A fireproof window It is necessary to provide insulation on the floor. The fire resistance of the walls around the evacuation floor and the bulkheads in the evacuation floor shall not be less than 3.00h, and the bulkhead doors must be fire doors. Henan refuge bay door 2. As the equipment floor: 1) Gather various equipment and pipeline shafts into compartments. The flammable and combustible liquid or gas pipeline shall be located in the center, and the equipment pipeline area shall be separated from the fire prevention area and evacuation area. The fire prevention limit of the firewall is 3.00h or more. 2) The pipe shaft and machine room must be separated from the evacuation area, and the fire partition with a fire limit of 2.00h or more shall be used. Pipeline wells and equipment doors shall not be opened directly to the evacuation area. Class A fireproof window direct deal If you really need to enter the evacuation place, the distance from the entrance to the evacuation place must be at least 5m, and fire doors must be used in the evacuation room.
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. high quality Class A 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. Class A fireproof window direct deal 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.
Maintenance and cultivation of Henan fire rolling shutter All fire rolling shutters should be checked and tested once a week. The test content includes: fire rolling shutter escape function test. high quality Class A fireproof window After the fire roller shutter is in the linkage state and drops to the bottom, press any manual button on both sides of the fire roller shutter, and the fire roller shutter shall be able to rise to the limit position (or drop to the bottom again after a delay). The lifting, lowering and stopping test of the manual buttons on both sides of the fire shutter. The fire rolling shutter shall be able to operate according to the instructions, and the operation shall be stable without blocking, not to mention uneven running speed of the shutter, stacking of the shutter or derailment. Test of manual emergency device. The manual zipper is used to lift the fire shutter, and the manual quick release device is used to lower the fire shutter. The fire shutter shall be able to run smoothly. Simulate the fire signal for linkage test. It is required that the fire shutter should be able to descend according to the normal procedure, and the contents and parts displayed in the fire control room should be consistent with the actual situation. Check whether the sealing of fire shutter is intact and damaged. The inspection above Henan fire rolling shutter door shall be carefully recorded, and the problems found shall be solved in a timely manner without leaving hidden dangers. Check whether the appearance of the fire shutter is intact and whether the curtain surface is damaged. Henan fire shutter door The door leaf of Henan fire shutter door cannot move: sensor failure is the major cause of the fire shutter door leaf cannot move. When such a situation occurs, be sure to check whether the sensor signal light is normal. If it is not the fault of the sensor, it may be that the wire connector is loose, the belt falls off, the controller is burned, the foreign matter is stuck, the voltage is abnormal, and so on. Pay attention to check and eliminate them one by one. Class A fireproof window direct deal The door leaf of the fire rolling shutter jumps when opening and closing: the reason for this fault is very simple. If the track of the fire rolling shutter is jammed by foreign matters, it is necessary to check the tracks on both sides of the door leaf, remove the foreign matters, and the fault can be solved. The opening and closing speed of the fire shutter door leaf is too slow: customers often hear this situation. It may be that the speed adjustment of the national controller is too slow, or the belt is too loose, resulting in friction between the fire shutter door leaf and the guide rail. When handling, check these two parts. If the speed is too slow, adjust them faster. If the belt is too loose, tighten it in time.
Why is Henan fire rolling shutter an indispensable facility?
