Centrifugal fans | HVAC fans | axial fans of professional maintenance and installation, Asia Fan Beijing agent phone (1) centrifugal fan?. After axial airflow into the fan impeller mainly along the radial flow. Such fan made according to the principles of centrifugal force, the products include centrifugal fans, centrifugal blowers and centrifugal compressors. (2) axial fans. Axial airflow into the fan impeller, approximately on the surface of the cylindrical flow in the axial direction. Such fan including axial fan, axial fans and axial compressors. 4-72-A centrifugal blower impeller - the 10 backward airfoil blades, curved wheel cover and the plate after plate composed of steel plate (B4-72 with cast aluminum alloy) manufactured by static and dynamic balance correction and overdrive experiment, high efficiency, stable and reliable operation, good air performance. Cabinet - made of two different types, including: №2.8 ~ 12 chassis made whole, can not be disassembled. №16 ~ 20 chassis made of three open, in addition to the level of two halves, the upper half vertically along the center line into two halves, bolted to install, add or remove impeller maintenance. Inlet - into the overall structure, mounted on the fan side, parallel to the axial cross-section shape of the curve, the role can flow smoothly into the impeller, and a smaller loss. 4-72-A centrifugal blower of 4-72-A centrifugal fan as general indoor ventilation factories and large buildings can be used as an input gas, also used as export gas. Air and other non-spontaneous, harmless, non-corrosive steel material gas. 4-72-A centrifugal fan 1 routine maintenance regularly to remove dust, dirt and water and other impurities within the fan and gas pipelines, and prevent rust. 2, the repair of the fan must be shut off, and never allow the operation, the switch should someone care to prevent transmission halfway. 3, on the subject of the sensitivity of the thermometer and the oil should be checked regularly. 4, in addition to the lubricant should be replaced after each overhaul, the lubricant should be changed regularly. 5, should be carefully recorded before and after each repair, inventory, check the number of tools and materials, to prevent forgetting internal fan duct. 6, the fan can not stop import and export orientation test within one meter. 7, installation, repair and test the presence of unrelated persons prohibited onlookers.
