    FRP Fan Overview:

    FRP fan refers to the fan made of glass fiber reinforced plastic. Its appearance and dimensions are exactly the same as steel fans, except that the casing and impeller are made of glass fiber reinforced plastic. Its biggest feature is corrosion resistance, acid and alkali resistance, and it belongs to a type of anticorrosive fan. It is suitable for ventilation and exhaust in office buildings, shopping malls, theaters, hospitals, factories and factories, basements and other places. The gas to be transported should not contain viscous substances, and the temperature of the gas should not be greater than 80 ° C, and the mass of the medium should not be greater than 150mg. / M3.

    Structural features of FRP fan:

    Impeller: The impeller is a steel-lined FRP structure. There are 12 blades for 9-19 fans and 16 blades for 9-26 fans, all of which are forward curved blades. The maximum peripheral speed of the outer edge of the impeller diffuser does not exceed 140m / s. After the impeller is shaped, it is corrected for static and dynamic balance, with excellent air performance, high efficiency, and stable and reliable operation.

    Case: The case is a snail made of fiberglass. No. 2.8 ~ 12.5 case is made as a whole and cannot be disassembled. The casings of No.16 and No.20 are made of two-open type, divided into two halves along the mid-level horizontal plane, and connected by bolts.

    Air inlet: The air inlet is made of a convergent streamlined overall structure, which is installed on the side of the fan; the section parallel to the axial direction is a curved shape, which allows the gas to enter the impeller smoothly, and the loss is relatively small.

    Transmission group: The transmission part is composed of main shaft, bearing box, coupling and so on. The main shaft is made of high-quality steel. The overall structure of the bearing box uses ball bearings, which are lubricated with bearing grease.
