How to Set up Performance Test of Fire Damper in Smoke Prevention Zone

Release Time：2021-07-21

First, the smoke exhaust port adopts a normally open type air outlet. Normally closed smoke exhaust fire damper is set on the smoke exhaust branch pipe of each smoke prevention zone, and normally open smoke exhaust fire damper is set at the entrance of the smoke exhaust fan. When a fire occurs in a smoke prevention zone, manually or automatically open the normally closed smoke exhaust fire damper on the smoke exhaust branch pipe, and at the same time, chain start the smoke exhaust fan to exhaust smoke. When the smoke temperature exceeds 280°C, automatically close the exhaust valve, at the same time, the chain closes the exhaust fan to stop the exhaust.
In case of fire in multiple smoke prevention zones, manually or automatically open the normally closed smoke exhaust fire dampers on the smoke branch pipes of these fire smoke prevention zones, and at the same time chain start the smoke exhaust fan to exhaust smoke. When the smoke temperature of a fire smoke prevention zone exceeds 280°C, automatically close the smoke exhaust fire dampers on the smoke exhaust branch pipes, and continue to exhaust smoke in other fire smoke prevention zones, only when the smoke exhaust fire dampers on the smoke exhaust branch pipes of all fire and smoke prevention zones are automatically closed due to the smoke temperature exceeding 280°C, the smoke exhaust fan will be closed in chain to stop smoke exhaust.
Second, the smoke exhaust port adopts normally closed type air outlet, each smoke partition smoke exhaust branch pipe is equipped with normally open smoke exhaust fire damper, smoke exhaust fan inlet is equipped with fire damper normally open smoke exhaust fire damper, when a fire occurs in a smoke partition, manually or automatically open the normally closed smoke exhaust port of the smoke partition, at the same time chain start the exhaust fan to exhaust smoke, when the smoke temperature exceeds 280°C automatically close the smoke exhaust valve on the smoke exhaust branch pipe, at the same time, the chain closes the exhaust fan to stop the exhaust.
Performance testing and analysis of smoke exhaust from fire dampers.
There are two inspection items for smoke exhaust fire damper products: closing reliability. In 10 closing operations, the fire damper should be able to close flexibly and reliably from the position in the opening and closing operations. The parts of the fire damper should be free from obvious deformation, wear and other damage affecting its sealing performance.
The reliability of closing in case of fire: use alcohol lamp or other fire sources to melt the temperature sensor of the fire damper. After the temperature sensor is activated, the fire damper should be automatically closed and reliably closed, including: the smoke exhaust fire damper is automatically closed, the gap between the blades or between the blades and the baffle is not more than 2mm, the gap between the blades or between the blades and the baffle is measured with a feeler gauge, and the opening reliability is after 10 opening tests, both electric and manual smoke exhaust valves shall be opened immediately, and the manual operation of smoke exhaust fire damper shall be convenient, flexible and reliable.
