For a certain period of time, the fire-proofing curtains, together with the curtains whose framework meets the requirements for fire-resistant stability and integrity, consist of curtains, scrolls, electrical motors, tracks, stairns, shields and control agencies。
Fire-proof curtains are used primarily for walls that require fire-proof separation, especially when large openings are required for production, use, etc., and cannot be fitted with fire doors。
Quick roll door frame:
The fast-rolled curtain door frame is based on a 2. 0 mm steel-heavy, high-quality, cold-rolled steel, processed by a fine roast paint or fluoride powder spray process, ensuring the beauty and durability of the door frame. At the same time, the door frame material may also select a high-quality aluminium alloy pole of 2. 0 mm thick stainless steel or 3. 5 mm thick antioxidizing treatment to meet the needs of different customers。
In terms of control, the soft curtains are equipped with control boxes in which the operator can easily perform the “open” “cut off” operation. In addition, control buttons can be set on the wall near the control box to allow remote manipulation. At the same time, automatic shut-down functions such as remote operations, radar detection or geomagnetic sensing can be provided on demand. On both sides of the door hole there is an infrared monitoring device, and once obstacles are encountered in the door movement through the door hole, the drapes cease immediately or automatically return to the open state to ensure safety。
In response to the problem of fast-rolling curtains, we conducted a detailed question-checking exercise, possibly for the following reasons:
Wires are cut off and need to be located and connected。
The brakes are glued and you can try to pull the chain manually to make it rotate。
Relay loops are damaged or oxidized and need to be replaced or grounded。
The limit switch is often not accessible to the contact point and can grind the point or replace the limit switch。
Bridge integrators or electromagnetic wires are damaged, causing brakes to die and the corresponding parts shall be replaced。
Overheating protection has failed and overheating protections need to be replaced。
Operating capacitor damage (for single-volume curtain doors) should be replaced。
The electrical plant is disconnected from thermal protection due to the length of its continuous operation and is expected to recover as the temperature of the electrical plant decreases。
