    F4-57 stainless steel corrosion resistant centrifugal fan

    1.Use

    F4-57 type anti-corrosion centrifugal fan is suitable for conveying various corrosive gases, the temperature of the conveying medium is not higher than 50 ° C, and the dust concentration of the gas is not greater than 150mg / m3.

    Form

    1) This fan is a single suction fan. The machine numbers are composed of 14 machine numbers such as №3.15, 3.55, 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2, 12.5, 14 and so on.

    2) The fan can be made in counter-rotation or counter-rotation, viewed from one end of the motor. If the leaf rotates clockwise, the fan is called “spin”; otherwise, it is called “counter-rotation”. Means.

    3) The position of the fan is indicated from the exit angle of the casing. For №3.15, 6.3 "reverse" and "shun" can be made into 6 angles of 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees. For №7.1 ~ 14, 5 angles such as 0 degree, 45 degree, 90 degree, 135 degree, and 180 degree can be made.

    4) The transmission mode of the fan is D type.

    5) For other forms, it can be specially designed.

    3. Structural form

    F4-57 fan is mainly composed of casing, air inlet, leaves, transmission group, leak-proof cover, air baffle, base and so on.

    1) The casing is a snail or polygonal shell made of corrosion-resistant material.

    2) The air inlet is welded with anti-corrosive material and has a windshield.

    3) The impeller is welded by corrosion-resistant materials. It consists of 12 backward double-arc veneer blades, which are composed of the wheel cover and the wheel disc. After dynamic and static balance correction, it has good aerodynamic performance and stable and reliable operation .

    4) The transmission group is composed of a bearing box, a bearing, a main shaft and a coupling.

    4. Performance and selection

    This manual only provides the dimensionless performance table of the No. 5 prototype, which can be used to convert the dimensioned performance of each fan in this manual.
