Today, the fire damper manufacturer and everyone are looking at some contents of the 3C fire damper. Let's take a look at the processes that the 3C fire damper needs to go through when it is finished.
There are two inspection items for 3C fire damper products: closing reliability. During the ten closing operations, 3C fire damper shall be able to be flexibly and reliably closed from the position during the opening and closing operations. All parts shall be free from obvious deformation, wear and other damages affecting its sealing performance. The reliability of closing in case of fire is that alcohol lamp or other fire sources are used to melt the temperature sensor of 3C fire damper. After the temperature sensor is activated, 3C fire damper shall be automatically closed and reliably closed, including: 3C fire damper shall be automatically closed; 3C fire damper is automatically closed; The gap between the blades or between the blades and the baffle is not more than 2mm.
After ten opening tests, both electric and manual 3C fire dampers will be opened immediately. Electric operation performance Electric operation performance 3C fire damper should be opened flexibly and reliably when it is 15% lower or 10% higher than the rated working voltage. Opening signal output function 3C fire damper shall have opening signal output function.
Electric operation performance: make 3C fire damper in closed state and connect with DC24V power supply, turn on the power supply in closed state and connect with the power supply, observe 3C fire damper, turn on the power supply, observe the opening state of 3C fire damper, turn on signal output function, turn on signal output function, turn on 3C fire damper, and use multimeter to measure the opening signal.
The above is about the relevant content of 3C fire damper, more knowledge, please continue to pay attention to our website!
