Factory direct F4-72-11-N0.2.8A FRP centrifugal fan

 (1) The use of fans F4-72 centrifugal fan is mainly used for conveying corrosive gas, but by gas shall not contain sticky substance contained in dust and hard particles should not exceed 150mg/m3, the gas temperature must not exceed 80 ° C . F4-72 centrifugal fan made of stainless steel, glass, steel or other corrosion-resistant materials, performance and foundation size 4-72 type centrifugal fan. (2) Type of fan from the motor side of the front, clockwise rotation of the impeller, said the right-hand fan, the "right"; known as L-blower impeller reverse rotation of the needle, the "left". The export position of the fan to the chassis to the outlet point. F4-72 type wind turbine № 2.8 to 6 factory are made of a type, the use of units required to install into the desired position, ordering is not indicated. Which № 2.8 out of the outlet position adjustment range is from 0 ° to 255 °, the interval is 45 °; the № 16 outlet location made three fixed 0 °, 90 °, 180 °, and can not be adjusted when ordering. The fan drive there are A, B, C, D of four :4-72 fan, № 2.8 to 6 A-type transmission, № 8 to 12 using the C, D-type transmission, № 16 B drive. 3 No. 2.8 to 6. 4-72 blower fan structure mainly by the impeller, housing, air inlet, motor and other components. № 8 ~ 16 In addition to having the above section, the transmission section. (1) impeller: 10 backward curved airfoil blades, curved front plate and the plate after plate, steel plate, and by the dynamic and static balance correction, good air performance, high efficiency, smooth operation. (2) Chassis: made of two different types. № 2.8 to 12 chassis made whole, can not be apart, № 16 casing made of three open along the carved horizontal plane is divided into two halves, the upper half vertically along the centerline divided into two halves, with bolt connection. (3) air inlet: made overall, mounted on the fan side, parallel with the axial cross-section curve switching action can flow smoothly into the impeller, and a smaller loss. (4) Transmission: shaft, bearing housing, mobile bearings, pulleys or couplings. Applicable to chemical, metallurgy, textile, food, pharmaceutical, oil and other industries, exhaust gas temperature, air conditioning, mist purification and delivered containing acidic gases may need to atmospheric corrosion resistance and other occasions. Can be used as an input gas, can also be used as the output gas. Especially suitable supporting the use of various types of exhaust gas purification tower. The ideal auxiliary device of the exhaust gas purifying tower.
