The aluminum roof is installed on the roof for exhaust gas replacement. Due to the particularity of the installation and use environment, the special material and structure are determined.
The aluminum roof fan is set to prevent air backside after a shutdown, because the air pressure rotates at a high speed at the heat pressure, causing the wind speed in the air cylinder to increase a lot. The wind turbine is not good for the startup of the motor, and it may be damaged due to the large start current.
The aluminum roof fan should have the performance of reliable rain, anti -snow, and wind -proof sand. Wind snow and wind sand are not like rain, because flying snow and wind sand will not only enter the fan from the upper part, but the outdoor wind speed reaches a certain intensity.Next, it may also enter the fan from the lower part.
Technical measures to install aluminum roof fan
1. Familiar with drawings before construction, and the problem of difficult drawings is solved as much as possible before construction.Before starting the construction, all personnel have a technical interchange, and the fan installation construction procedures, technical requirements, and quality inspection standards are correctly mastered.
2. The specifications, materials, models and quality of equipment and materials meet the design requirements. The equipment should have a qualified certificate, and the material must have a quality guarantee.The use of various materials is strictly constructed in accordance with the construction drawings, and those who do not meet the requirements of the norms must be rectified immediately.
3. Processing and production parts should meet the technical quality requirements of the drawings, and can only be installed after the supervision and inspection are recognized.
4. Do a good job of self -inspection during the construction process, and accept the supervision and inspection of the relevant personnel of the on -site supervision and engineering department at any time.Strengthen self -inspection and mutual inspection.
5. Determine the height control point and axis center line of the foundation of the fan through on -site control point network.
6. On -site welds are constructed by qualified welders to strengthen welding quality control.
7. Waterproof construction must first clean the surface oil, dust, and after the debris can be applied.
The above is the introduction of the installation of aluminum roof fans
