características do produto
1. The transmission mode of the fan includes A B. C, D four types: No2.8~5 adopts A-type transmission, No6 has both A-type and C-type transmissions, and No8-12 uses C There are two types of transmission modes in Type D, Não 16-20 adopts B-type transmission;
2. Ventilation fans numbered 2.8A-6A mainly consist of impeller, casing, air inlet, motor, and other parts, No6C and No. 8-20 not only have the above structure, but also have a transmission part;
3. Impeller: composed of 10 rear tilting machine airfoil blades, curved wheel covers, and flat rear discs, made of steel plate or cast aluminum alloy. After dynamic and static balance correction and overspeed operation experiments, it has high efficiency, smooth and reliable operation, and good air performance;
4. Housing: Made in two different types, among which: No2.8~12 casings are made as a whole and cannot be disassembled. The No16~20 casing is made into a three open type, which is divided horizontally into two halves. The upper half is vertically divided into two halves along the centerline and connected with bolts for easy insertion or removal of the impeller during installation and maintenance;
5. Air inlet: Made into a complete structure and installed on the side of the fan, with a curved section parallel to the axis, the function is to allow the airflow to smoothly enter the impeller with minimal loss;
6. Transmission: composed of spindle, bearing box, rolling bearings, pulley or coupling;
7. Tubo de aço ou fiação de cabo, with grounding screws inside and outside the motor casing;
