What are the precautions for fire smoke that can give us life safety guarantee at critical time?It is more than a hundred years as the so -called foundation. When assembling firefighting smoke, there are a few important things that we cannot ignore. Lets talk about some commonly used hoods that need attention during the assembly process.Bar.
1. The range and gap range of the axial flow and centrifugal assembly are different
The axial flow fans are important is the radial gap between the fan and the impeller. During the range of the machine number (≤10), the space range (≥3.5mm), the range of the machine number (≥10), the gap range (≥ ≥ 10) (≥ 10) (≥ 10)4.5mm).The centrifugal foam foam fan is uniform because the radial unilateral gap value is relatively uniform, and the diameter range is generally (0.15%~ 0.4%).
2. Paint treatment in appearance, keep color unchanged under 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 °.
3. Check whether the assembly parts are stable and reliable
The component of fire foam fan may also produce loosening parts and affect the normal work of the machine. All fasteners must be evenly firm and take corresponding anti -loose measures.The harm caused by loosening parts is the fatal injury of industrial machinery. In order to ensure the normal work of the machine, the anti -loose measures of the screw must be treated with caution.
