    4-72 FRP anticorrosive fan

    1.Application FB4-72 centrifugal fan casing, impeller and air inlet are all made of FRP, so it is suitable for industries with strong corrosive industries such as petroleum, chemical industry, non-ferrous metallurgy, electroplating, sewage treatment, brewing and electronics industries. Gas venting.

    2. Form FB4-72 FRP centrifugal fan (№) indicates the outer diameter of the impeller. (Such as №5, that is, the impeller outer diameter D2 = 500 mm.) The product is divided into right-handed and left-handed. When viewed from one end of the motor, the impeller rotates clockwise to right-handed and vice versa.

    FB4-72 FRP centrifugal fan is divided into A type, C type and D type (A type is directly connected with the motor; C type is connected by a pulley; D type is connected by a coupling), and it is equipped with a domestic Y series motor .

    3. Structural characteristics FB4-72№2.8 ~ 6A FRP centrifugal fan is mainly composed of impeller, casing, air inlet, frame and other parts directly connected to the motor; 6C ~ 12C, D and 16, 20B fans have the above structure, There is also a transmission section.

    1) The impeller consists of 10 backward curved wing-shaped blades, arc-shaped front discs and spacer discs, all made of FRP.

    2) The casing is made of FRP.

    3) The air inlet is also integrally formed with glass fiber reinforced plastic. The cross section parallel to the axial direction is a curved shape.

    4) No. 2.8 ~ 8A (C, D) fan casing, motor (or transmission group) are fixed on the frame with bolts, which has good integrity. №10 ~ 12C and 16,20B style adopts metal 4-72 fan drive unit with the same machine number.
