Fire fire smoke is widely used in high -rise buildings, baked houses, underground garages, subways, tunnels and other occasions.According to the GA211-1999 fire resistance high temperature test method, it can run continuously for more than 100 minutes under high temperature conditions at 400 ° C. The medium temperature is continuously run for 20 hours/time without damage. It has been recognized by the fire department of major cities across the country.There are several points when assembling firefighting to smoke. We cannot ignore it. Lets talk about the matters that are commonly used in the assembly process.
The range and gap range of the axial flow and centrifugal assembly are different
The axial flow fan is more important. The radial gap between the fan and the impeller. When the range of the machine number (≤10), the range of the gap (≥3.5mm), the range of the machine number (≥10), the gap range (the gap range (≥4.5mm).Due to the average cycling values ??of the centrifugal line, the diameter range (0.15%~ 0.4%) is generally uniform.
The appearance is painted, and the color is not changed in the high temperature environment
The paint is needed in the inside and outside of the tobacco fan. The request is that the basic requirements of unchanged color can be maintained when the material temperature transmitted by the ventilator reaches 280 °.
Check whether the assembly parts are stable and reliable
The component may also produce loosening of parts and affect the normal work of the machine. All fasteners must be uniform and firm, and do the corresponding anti -loose measures.The harm caused by loosening parts is the fatal injury of industrial machinery. Although the structure of the fire prevention valve is not very precise, it is also a small fatal problem that cannot be ignored. In order to ensure the normal work of the machine, the screw prevention measures must be treated with caution.
The above is the assembly point of the fire firing fan. Only the correct assembly equipment can ensure its normal operation.For more relevant information, please pay more attention to us- ——
