Some problems easily occur in the installation of fireproof rolling shutter door

One problem: the strength of the transmission device of the fire resistant rolling shutter door. The strength of the roller shutter shaft is also an important parameter of the rolling shutter door. At present, there are many products with unqualified 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.

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.

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.

The fourth problem: fire control electric cabinet, smoke and temperature sensing, and the national standard regulations on fire temperature control and door closing. When a fire occurs within 2m of the fire rolling shutter door. The power supply is interrupted. When no one is operating on site, there should be a fire temperature fuse control door closing device, which is especially important for crowded places. I hope you will pay attention to the above questions. It is also a very important question how to install the fireproof rolling shutter door and how to make it firm.

What are the purchasing methods of fireproof rolling shutter doors? Next, the manufacturer of fireproof rolling shutter door will give us a brief introduction.

1. Investigate whether the layout of the electric fire shutter door is precise, whether the lubrication degree is good or not, and compare the heat dissipation of the good electric fire shutter door. Select full gear rotation, no chain, no belt, thus enhancing the overall life of the fire shutter door movement. Henan fireproof rolling shutter door

2. Whether the electric fireproof rolling shutter door supports the manual function, and the manual function should be convenient and convenient. In case of power failure, change the clutch by 90 degrees, and then push it manually.

3. The electric fireproof rolling shutter door shall not have the appearance of inertia sliding, and shall have the function of double-sided active locking. Henan fireproof rolling shutter door

4. In order to improve the smooth operation of the electric fireproof rolling shutter door and increase the tension, the factory selects the production and installation technology of 8-wheel front and rear drive and continuous row gear rotation.
