The centrifugal fan is to rely on mechanical energy input, increase gas pressure gas side mechanical transmission, it is a slave fluid machine. Centrifugal fans are widely used in factories, ventilating mines, tunnels, cooling towers, vehicles, ships and buildings, dust emission and cooling; boiler and industrial furnace ventilation and the wind; air-conditioning equipment and household appliances and cooling equipment ventilation; grain drying and sending; wind tunnel source and inflatable hovercraft and propulsion. First, the wind chassis installation requirements 1, the product is installed after the wind chassis performance, better check the equipment required is a three-phase or single-phase voltage. 2, the fan after installation HTFC-11 dual-speed wind chassis, hand struck the rotor, check whether there is too tight or collision phenomenon, in the absence of these phenomena turn before trial. 3, note the direction of rotation of the impeller. 4. When installing the fan, the weight of the gas pipeline should not be added to the cabinet.
